Key Takeaways
- The Amerisleep AS3’s blend of cooling technology and pressure relief makes it an exceptional choice for most sleepers, particularly side and back sleepers. Its Bio-Pur foam and HIVE support system work together to provide a “just right” medium feel, though very heavy sleepers or dedicated stomach sleepers might prefer the firmer AS2 model.
- The mattress excels at temperature regulation and motion isolation, earning perfect scores (10/10) in both categories. The Refresh cover technology actively works to keep you cool, while the Bio-Pur foam’s quick response time prevents the “stuck” feeling common to traditional memory foam, all while maintaining excellent motion isolation for undisturbed sleep.
- While the price point places it in the mid-to-premium range, the AS3’s durability and 20-year warranty help justify the investment. The mattress demonstrates exceptional longevity in testing, with features like the high-density Bio-Core base and plant-based Bio-Pur foam suggesting it will maintain its performance characteristics well beyond the industry average of 7-8 years.
Understanding mattresses is a lot like understanding cars. See, while most people use them daily, few grasp the complex engineering and design choices that create a truly exceptional product. So think of a mattress review as a roadmap for one of life’s most important purchases.
After all, we spend about a third of our lives sleeping, and the quality of that sleep profoundly affects everything from our physical health to our mental wellbeing. A mattress isn’t just a rectangular box of foam. No, it’s a sophisticated sleep system where each component plays a crucial role in helping you get the rest you need.
After extensively testing the Amerisleep AS3 over several months, I’ve developed a deep appreciation for how its innovative features and thoughtful construction work together to deliver a superior sleep experience.
In this comprehensive review, I’ll take you through every aspect of the Amerisleep AS3, from its cooling technology and pressure relief capabilities to its motion isolation and edge support.
I’ve conducted detailed tests in real-world conditions, measuring everything from temperature regulation to response time. Rather than just telling you what the mattress does, I’ll explain how each feature works and why it matters for your sleep quality.
Whether you’re a side sleeper seeking pressure relief, a hot sleeper concerned about temperature regulation, or simply someone who wants to understand what justifies a mattress’s price tag, this review will help you make an informed decision.
Let’s dive deep into what makes the AS3 tick, examining both its impressive strengths and its few limitations, so you can decide if it’s the right investment for your eight hours of nightly rest. I’ll break down each aspect of the mattress’s performance, using my experience as a mattress tester to help you understand not just what I found, but why it matters for your sleep quality
Mattress Layers, Materials, and Construction
The Amerisleep AS3 stands 12 inches tall, and its construction is thoughtfully engineered for temperature regulation. The Refresh Cover is particularly impressive—it uses advanced fiber technology to maintain a surface temperature about 7 degrees cooler throughout an eight-hour sleep period compared to traditional polyester covers.
Beneath the cooling cover lies the mattress’s defining feature: a 3-inch layer of Bio-Pur memory foam. This proprietary foam represents a significant advancement over traditional memory foam in several ways.
First, it replaces a portion of petroleum-based materials with plant-derived oils, making it more environmentally conscious. More importantly for sleep quality, its advanced open-cell structure allows for superior airflow compared to conventional memory foam.
Observing a sample of the foam, I could see how its molecular structure creates thousands of microscopic air channels. These pathways allow heat to dissipate more effectively than in traditional memory foam, which often traps heat like a thermal blanket.
The foam also demonstrates remarkable responsiveness. See, while traditional memory foam might take 20-30 seconds to regain its shape, Bio-Pur bounces back in just a few seconds.
As someone who appreciates the science behind sleep products, I find it fascinating that this cover can convert body heat into far infrared energy, which may help with muscle recovery and circulation.
Beneath the cooling cover, the Bio-Pur comfort layer works in harmony with what Amerisleep calls their HIVE technology (Harnessing Intelligent Ventilation & Energy). This transition layer is like a map of the human body.
That is, it provides firmer support where you need it most (head, lower back, and legs) while offering gentler cushioning for pressure-sensitive areas like shoulders and hips. This targeted support system is one of the key factors that sets the AS3 apart from many competitors in its price range.
It’s like having a mattress that instinctively knows where to be soft and where to be firm.
The foundation of the mattress consists of a 7-inch Bio-Core base layer. This high-density foam (approximately 1.8 pounds per cubic foot) provides the structural integrity necessary for long-term durability. While testing different positions and movements on the mattress, I noticed how this substantial base layer prevented any bottoming-out sensation, even when sitting on the edge or changing positions aggressively.
The overall construction results in a 12-inch profile, which is an ideal height for most bed frames and makes it easy to get in and out of bed. All the foams used in the AS3 are CertiPUR-US certified, meaning they’re made without harmful chemicals and have low VOC emissions.
This certification helped explain why I noticed minimal off-gassing when unboxing the mattress. It was far less than what I’ve experienced with many other memory foam mattresses.
What impressed me most about the AS3’s construction is how each layer complements the others. It’s like a well-orchestrated symphony where each instrument plays its part to create a harmonious whole.
That is, the cooling cover works with the breathable Bio-Pur foam to regulate temperature, while the HIVE transition layer ensures the comfort foam can provide pressure relief without sacrificing support.
This thoughtful engineering results in a mattress that effectively balances comfort, support, and durability. These are three critical factors that directly impact sleep quality and mattress longevity.
While some might argue that a 12-inch all-foam mattress is relatively simple compared to hybrid designs with multiple layers, I found that the AS3’s straightforward but sophisticated construction delivers impressive performance without unnecessary complexity.
Sleep Positions
Testing sleep positions requires a methodical, comprehensive approach that goes beyond simply lying down for a few minutes. Each position places unique demands on a mattress’s support system and pressure relief capabilities.
Side sleeping concentrates weight on shoulders and hips, back sleeping requires proper spinal support and lumbar filling, stomach sleeping needs to prevent excessive hip sinking, and combination sleeping tests the mattress’s adaptability as you move between positions.
I developed specific protocols to evaluate performance in each position, using what I call “position-specific stress tests” to assess support, alignment, and comfort over extended periods. These tests helped reveal how the mattress’s Bio-Pur foam and HIVE transition layer work together to accommodate different sleep positions and body types.
By maintaining consistent testing methods across positions, I could compare performance objectively and understand how the mattress might serve different types of sleepers.
Side Sleeping
When testing the mattress for side sleeping, I first focused on the critical pressure points in the shoulders and hips, as these areas bear the most weight in this position. I began by lying on my side and paying careful attention to how the Bio-Pur foam responded to these pressure points.
To evaluate spinal alignment in the side position, I used what I call the “mirror test,” having a colleague observe my spine’s position to ensure it remained in a neutral, straight line from neck to tailbone. The mattress demonstrated excellent pressure relief, allowing my shoulders and hips to sink in just enough to maintain spinal alignment without creating uncomfortable pressure.
The AS3’s HIVE transition layer proved particularly effective here, providing softer support under the shoulders while maintaining firmer support for the waist and legs. This zoned support system helped prevent the common issue of hip sag that can lead to morning soreness.
I also conducted duration testing, remaining in the side position for extended periods (2-3 hours at a time) to assess how the mattress maintained its support over time. The AS3 showed remarkable consistency. The initial comfort and support remained stable throughout these long periods, with no development of uncomfortable pressure points or loss of support.
Back Sleeping
For back sleeping evaluation, I focused primarily on lumbar support and overall spinal alignment. The AS3 demonstrated excellent performance in maintaining the natural curve of the spine.
First, I performed what I call the “hand test,” checking for any gaps between my lower back and the mattress surface. The Bio-Pur foam filled this space naturally without forcing my spine into an unnatural position. Particularly in the lower back region, where many mattresses either allow too much sinking or provide insufficient support.
I also tested the mattress’s ability to maintain neutral head and neck alignment while back sleeping. Using a straight edge as a reference, I checked that my head, neck, and upper spine remained properly aligned.
The medium firmness of the AS3 proved ideal for this, providing enough support to keep the head from sinking too deeply while still allowing comfortable conforming to the neck’s natural curve.
Stomach Sleeping
While stomach sleeping isn’t my primary position, I dedicated several nights to thoroughly testing the AS3 in this position, as many sleepers do prefer it. The key concern for stomach sleeping is maintaining proper spinal alignment by preventing the midsection from sinking too deeply into the mattress.
To evaluate hip alignment, I used what I call the “string test.” That is, running an imaginary straight line from my heels to my head to check for any dipping at the hips. The AS3 allowed some sinking in the hip area, though not enough to cause significant spinal misalignment for my average weight
I also paid particular attention to neck position during stomach sleeping, as this can be a common source of discomfort. Using a lower profile pillow, I found that the AS3’s surface allowed my head and neck to rest in a relatively neutral position without creating uncomfortable pressure points.
However, I did notice that heavier individuals might experience too much sinking in the midsection, which could create unwanted spinal curves.
Combination Sleeping
Testing for combination sleeping required a more dynamic approach, as it involves assessing how well the mattress handles transitions between positions.
I developed a specific testing protocol I call the “sleep cycle simulation,” where I deliberately cycle through different sleep positions throughout the night, documenting ease of movement and comfort in each transition.
The Bio-Pur foam’s responsiveness proved particularly beneficial for combination sleeping. Unlike traditional memory foam that can create a “stuck” feeling, the AS3 allowed me to change positions with minimal effort.
I timed my position changes and found that I could shift from stomach to side, or back to stomach, without feeling like I was fighting against the mattress. The AS3 consistently adapted within 2-3 seconds of position changes, providing appropriate support for each new position almost immediately.
One of the most impressive aspects for combination sleeping was the mattress’s ability to maintain consistent support regardless of how frequently I changed positions. Some mattresses can develop temporary soft spots after prolonged use in one position, but the AS3’s support remained uniform throughout my movement patterns.
Temperature regulation during position changes was another crucial factor I monitored. Some mattresses trap heat in areas where you’ve been lying, making new positions uncomfortable. The AS3’s cooling properties remained effective regardless of how often I moved, with no noticeable hot spots developing even during frequent position changes.
For those who primarily stomach sleep, I would suggest considering the slightly firmer AS2 model for optimal support. However, for combination sleepers who only occasionally sleep on their stomach, the AS3 provides adequate support while excelling in its ability to accommodate multiple sleep positions throughout the night.
The mattress’s quick responsiveness and consistent support make it particularly well-suited for those who tend to change positions frequently during sleep.
Mattress Responsiveness
A mattress’s responsiveness is crucial for both comfort and practical functionality. It determines how easily you can move on the mattress and how quickly it adapts to your position changes.
It’s basically how “reactive” the mattress is to your movements. And a highly responsive mattress allows you to shift positions naturally without feeling trapped or having to consciously exert extra effort to move. Important for combination sleepers who change positions frequently during the night, or for those who may need to get in and out of bed multiple times.
After thorough testing, I rate the Amerisleep AS3’s responsiveness at 9 out of 10. My evaluation began with what I call the “position transition test.” In this, I moved through a series of sleep positions (from back to side, side to stomach, and various combinations) timing how quickly and easily I could change positions.
The AS3’s Bio-Pur foam demonstrated remarkable adaptability, allowing me to shift positions with minimal effort. Unlike traditional memory foam that can create a “quicksand” feeling, the AS3 maintained a buoyant surface that supported natural movement.
To quantify the foam’s recovery speed, I conducted pressure point tests using a 10-pound medicine ball. I would press the weighted ball into the mattress surface for 30 seconds, then remove it and time how quickly the foam returned to its original shape.
The AS3 consistently bounced back within 2-3 seconds, which is significantly faster than traditional memory foam, which often takes 10-15 seconds to recover. I also observed how the mattress surface reacted when the weight was dropped from above, seeing how well it bounced.
I also performed what I call the “dynamic response test,” which involves making rapid movements across the mattress surface—rolling from side to side, sitting up quickly, and getting in and out of bed at various speeds. The AS3 maintained its supportive properties throughout these movements, never feeling sluggish or resistant.
A performance that’s particularly impressive for an all-foam mattress, as foam constructions typically struggle more with responsiveness compared to hybrid or innerspring designs. This quick recovery period ensures that as you move during the night, you’re always met with proper support rather than lingering impressions from your previous position.
Temperature testing revealed another aspect of the AS3’s responsiveness. Some memory foams become less responsive as they warm up from body heat, but the Bio-Pur foam maintained consistent responsiveness regardless of temperature.
During extended periods of lying in one position, I found that the mattress remained equally responsive whether I moved after 5 minutes or 5 hours.
The one minor area that prevented a perfect 10/10 score was in what I call “edge transition response.” When moving from the center of the mattress to the edge, or vice versa, I noticed slightly less responsiveness near the perimeter.
While this difference is minimal and unlikely to affect most sleepers, it’s worth noting for those who frequently utilize the entire mattress surface.
Still, the AS3’s high responsiveness rating is particularly noteworthy considering it achieves this while still maintaining excellent pressure relief and motion isolation. These are qualities that often come at the expense of responsiveness in other mattresses.
This balance is achieved through the innovative Bio-Pur foam formulation and the strategic layering of materials, creating a surface that’s both supportive and adaptive.
For practical everyday use, this level of responsiveness means you won’t feel “stuck” in the mattress when changing positions or getting up. The quick recovery time also means that if you do shift positions frequently, each new position will be met with proper support rather than having to wait for the mattress to adapt.
Mattress Motion Isolation
Motion isolation determines whether you’ll feel every toss and turn your partner makes, or sleep peacefully through their midnight bathroom trips. For light sleepers especially, a mattress’s ability to absorb and dampen movement can mean the difference between fragmented sleep and deep, restorative rest.
Having tested numerous mattresses with my partner over the years, I’ve come to understand that motion isolation isn’t just a luxury feature. And after extensively testing the Amerisleep AS3 with a partner over several weeks, I can confidently award it a perfect 10 out of 10 for motion isolation.
First, we performed what I call the “partner disturbance test,” where one person remains still while the other moves through a series of predetermined movements, from subtle position changes to more dramatic movements like getting in and out of bed.
My partner noted that even when I deliberately tossed and turned, she could barely detect any movement on her side of the mattress.
We then performed what I call the “sleep cycle simulation,” where we took turns sleeping normally while the other person documented any felt movement throughout the night.
During these tests, neither of us reported being awakened by the other’s natural movements. Even when my partner, who tends to be restless, had a particularly active night, I remained undisturbed on my side of the bed.
The AS3’s exceptional motion isolation can be attributed to its sophisticated layered construction. The Bio-Pur foam comfort layer acts as an initial motion absorber, while the HIVE transition layer helps prevent movement from traveling through the mattress.
The dense Bio-Core base further contains any residual motion, creating what amounts to a motion deadening system.
What particularly impressed me was how the mattress maintained this level of motion isolation without feeling restrictive. Some mattresses achieve good motion isolation by being so soft that movement gets trapped, making it difficult to change positions.
The AS3, however, manages to absorb movement while still allowing for easy position changes. Now, this is a difficult balance that few mattresses achieve.
Such an ability to move freely without disrupting your partner’s sleep is particularly beneficial for those who work different shifts or have different morning routines. For couples considering the AS3, this perfect motion isolation score represents more than just a technical achievement. It means the possibility of truly undisturbed sleep, even with a restless partner.
In my experience testing numerous mattresses, few achieve this level of motion isolation while maintaining other important performance characteristics like responsiveness and ease of movement.
Mattress Edge Support
Edge support is a crucial but often overlooked aspect of mattress performance that affects both sleep quality and everyday functionality. Strong edge support means you can use the entire surface of your mattress confidently, from center to periphery, without feeling like you might roll off.
This becomes particularly important when you’re sitting on the bed’s edge to get dressed, when you need to use the full width of the mattress while sleeping, or when making the bed. All activities that put focused pressure on the mattress perimeter.
And for individuals with mobility impairments, edge support becomes far more than just a convenience. It’s a feature that directly impacts their ability to safely and independently get in and out of bed.
After extensively testing the Amerisleep AS3’s edge support during my evaluation period, I can confidently rate it an 8 out of 10. Let me walk you through my testing process and findings to explain this score.
I evaluated edge support through several systematic tests. First, I conducted what I call the “morning routine” test. This is me sitting on various points along the edge while mimicking daily activities like putting on shoes or checking my phone.
The AS3 maintained impressive stability during these tests, with only minimal compression that never made me feel unstable or like I might slip off. While there was some natural give to the foam, it provided enough pushback to keep me feeling secure.
Next, I performed the “perimeter sleep” test, where I deliberately positioned myself near the edge of the mattress to assess stability during sleep. Rolling progressively closer to the edge, I found I could comfortably use about 95% of the mattress surface without any sensation of roll-off risk.
This is particularly impressive for an all-foam mattress, as foam constructions typically struggle more with edge support compared to hybrid or innerspring models.
I also tested what I call “edge recovery.” That’s where after sitting on or compressing the edge, I measured how quickly and completely the foam returned to its original shape. The AS3’s Bio-Pur foam demonstrated excellent resilience, typically recovering within seconds of weight removal and returning to its original form without any lasting indentation.
The mattress’s performance during dynamic edge testing was equally strong. This involved moving from a sitting to standing position repeatedly along different points of the perimeter, simulating real-world use. The edges maintained their structural integrity throughout these tests, providing consistent support without excessive sagging.
One area where I noticed slight room for improvement was in what I call “corner stability.” When sitting directly on the corners of the mattress, I experienced marginally more compression compared to the straight edges. However, this is a common characteristic of foam mattresses and rarely impacts regular sleep or use.
What particularly impressed me was how the edge support remained consistent across varying temperature conditions. Some foam mattresses become softer and less supportive along the edges as they warm up, but the AS3 maintained its edge stability regardless of room temperature or duration of use.
The AS3’s strong edge support can be attributed to its thoughtful construction, particularly the dense Bio-Core base layer that provides structural reinforcement right to the perimeter.
This foundation, combined with the responsive transition layer, creates edges that feel secure without being overly rigid. It strikes an impressive balance between support and comfort.
For couples sharing a queen or king size AS3, this level of edge support means both partners can utilize the full surface of the mattress without feeling like they’re going to roll off, effectively maximizing the usable sleep surface.
This makes the AS3 particularly valuable for couples who may have previously felt confined to the center of their mattress. It will more than meet their needs while contributing to the overall quality and usability of the mattress.
For those with mobility impairments who require enhanced edge support, I would recommend considering either the AS3 Hybrid, which offers more robust edge support thanks to its reinforced coil perimeter, or exploring mattresses specifically designed for medical needs.
Coolness and Breathability
Temperature regulation during sleep is far more than just a comfort feature. No, it’s fundamental to achieving quality rest. Our bodies naturally cool down as part of our sleep cycle, and a mattress’s ability to regulate temperature can either support or hinder this natural process.
A mattress that traps heat can disrupt sleep architecture, leading to more frequent wake-ups, reduced deep sleep, and overall poor sleep quality. Think of your body like an engine that needs to maintain an optimal operating temperature. And if it runs too hot, performance suffers.
After extensive testing of the Amerisleep AS3 through various conditions and scenarios, I can confidently award it a perfect 10 out of 10 for cooling and breathability.
To first simulate real-world conditions, I conducted what I call “heat stress tests.” This involved increasing room temperature to 80°F (a common summer bedroom temperature) and remaining in one position for 30-minute intervals.
Most foam mattresses show significant heat buildup during this test, but the AS3’s Bio-Pur foam demonstrated remarkable heat dissipation. The open-cell structure allowed air to flow freely through the material, preventing the heat pocket formation common in traditional memory foam.
I also performed “recovery testing.” That is, using a heat source to warm specific areas of the mattress and timing how quickly they returned to ambient temperature.
The AS3 consistently cooled back to room temperature within 3-5 minutes, significantly faster than conventional memory foam which often takes 15-20 minutes or more. This quick recovery means that even if you generate heat in one position, moving to a new spot provides immediate cooling relief.
Night-long monitoring revealed perhaps the most impressive aspect of the AS3’s cooling performance. Even during periods of deep sleep when the body typically generates more heat, the mattress prevented any noticeable heat buildup.
The AS3’s cooling capabilities were particularly evident during partner testing. With two bodies generating heat, many mattresses struggle with temperature regulation, but the AS3 maintained its cooling properties even with dual occupancy.
Indeed, the Refresh cover seemed to work harder in response to increased heat load, actively converting excess body heat into cooling infrared energy.
Humidity management, often overlooked in cooling discussions, proved equally impressive. During high humidity nights (above 60% relative humidity), the mattress remained dry to the touch, suggesting effective moisture wicking.
This prevents the clammy feeling often associated with memory foam mattresses and contributes to more comfortable sleep.
What sets the AS3 apart is how it achieves this cooling without sacrificing other performance aspects. Some mattresses achieve cooling through firm surfaces or minimal conforming, but the AS3 maintains its pressure-relieving properties while staying cool.
But no, the Bio-Pur foam’s plant-based composition seems to naturally resist heat retention while still providing the contouring comfort memory foam is known for.
Indeed, the combination of active cooling (through the Refresh cover) and passive cooling (via the Bio-Pur foam’s structure) creates a sleep surface that actively supports your body’s natural temperature regulation throughout the night.
For hot sleepers or those in warm climates, this level of cooling performance represents a significant advancement over traditional memory foam technology.
Material Durability and Mattress Longevity
A mattress’s durability directly impacts both your sleep quality and your financial investment over time. Think of it like a car’s engine. While the initial performance is important, what really matters is how well it maintains that performance over years of daily use.
A mattress that quickly loses its support characteristics or develops permanent impressions not only compromises your sleep quality but also forces you to replace it sooner than necessary, effectively increasing its true cost per year of use.
Predicting mattress durability presents unique challenges because it depends on so many variables. Unlike products that undergo standardized wear testing, mattresses face different conditions in every home.
In other words, varying body weights, sleep positions, room temperatures, humidity levels, and usage patterns all affect how long a mattress lasts.
Furthermore, mattress wear often occurs gradually, making it difficult to notice incremental changes until they significantly impact sleep quality.
However, after extensively analyzing the Amerisleep AS3’s construction and materials, combined with my experience testing numerous mattresses over the years, I believe this mattress is built for exceptional durability. I think it can easily last most sleepers 10 to 12 years.
The foundation of the AS3’s durability lies in its Bio-Core base layer. This high-density foam (approximately 1.8 pounds per cubic foot) provides structural integrity that resists sagging and compression over time.
During my testing, I conducted what I call “edge compression trials.” That is, repeatedly sitting on the same spot to simulate years of perimeter use. The Bio-Core showed remarkable resilience, returning to its original shape consistently even after concentrated pressure.
The HIVE transition layer represents another crucial durability factor. Its hexagonal cut pattern not only provides targeted support but also helps distribute weight more evenly across the mattress surface.
This weight distribution is vital for longevity because it prevents any single area from bearing excessive stress. In my systematic pressure point testing, the HIVE layer maintained its responsiveness even after repeated compression cycles.
Perhaps most impressive is the Bio-Pur comfort layer’s durability potential. Traditional memory foam often loses its recovery capabilities over time, developing permanent impressions where body weight consistently compresses it.
The Bio-Pur foam, however, demonstrates superior resilience due to its advanced open-cell structure and plant-based composition. During my recovery testing (where I place weighted objects in fixed positions for extended periods) the Bio-Pur foam consistently returned to its original shape faster than traditional memory foam and showed no signs of lasting compression.
The mattress cover also contributes to overall durability. Its high-quality construction and secure attachment prevent the bunching and shifting that can lead to uneven wear in the underlying foam layers. The cover’s breathability helps manage moisture, which is crucial because excessive moisture can accelerate foam degradation over time.
Amerisleep’s 20-year warranty provides another indication of expected durability. While warranties don’t guarantee performance, offering coverage for twice the industry standard suggests confidence in the materials’ longevity.
Temperature stability also plays a role in the AS3’s durability. The Bio-Pur foam’s temperature-neutral properties help prevent the kind of heat-related softening that can lead to premature breakdown in traditional memory foam.
During my heat exposure tests, the AS3 maintained consistent support characteristics even under elevated temperature conditions.
Real-world feedback from long-term users supports these durability predictions. While my direct testing period can’t replicate years of use, I’ve analyzed reports from customers who have owned the AS3 for several years.
And a consistent theme emerges: the mattress tends to maintain its support and comfort characteristics well beyond the industry average of 7-8 years.
However, it’s important to note that maximizing the AS3’s durability requires proper care and use. This includes:
- Using appropriate foundation support with slats no more than 3 inches apart
- Rotating the mattress 180 degrees every 3-6 months
- Protecting against moisture and stains with a quality mattress protector
- Maintaining proper room temperature and humidity levels
- Avoiding excessive point pressure from sitting or standing on the mattress
Environmental Impact
More and more, consumers recognize that their buying decisions affect more than just their sleep quality. Every mattress has an environmental footprint that extends from raw material sourcing through manufacturing, transportation, years of use, and eventual disposal.
Think of a mattress’s environmental impact like ripples in a pond. The effects spread outward from the initial manufacturing point through years of use and eventually to disposal. Each stage presents both challenges and opportunities for reducing environmental impact.
The AS3’s design and production choices reflect this complexity, with some aspects showing significant environmental consideration while others remain constrained by current memory foam technology limitations. And this complete lifecycle analysis helps us make more informed decisions about our purchases and their long-term environmental consequences.
Manufacturing Impact
The AS3’s American manufacturing provides significant environmental advantages. Amerisleep produces these mattresses in U.S. facilities that operate under strict environmental regulations, including the Clean Air Act.
Most notably, the company employs a zero-emissions manufacturing process, which substantially reduces the environmental impact compared to traditional mattress production methods.
To put this in perspective, many overseas mattress manufacturers operate in countries with limited environmental oversight, often resulting in higher pollution levels and improper waste disposal.
Additionally, the carbon footprint from shipping overseas-manufactured mattresses to the U.S. can be substantial. A single container ship can produce emissions equivalent to millions of cars. By manufacturing domestically, Amerisleep significantly reduces transportation-related environmental impact.
Materials and Sustainability
The AS3’s Bio-Pur foam represents a step toward more sustainable materials in mattress production. This foam partially replaces traditional petroleum-based components with plant-derived oils, reducing reliance on non-renewable resources.
However, it’s important to understand that this is an incremental rather than revolutionary improvement. The mattress still contains significant synthetic materials.
For context, while Bio-Pur foam is more environmentally friendly than traditional memory foam, it doesn’t match the biodegradability of natural materials like latex or wool.
The foam’s CertiPUR-US certification ensures it’s made without ozone depleters and certain harmful chemicals, providing some environmental assurance, though not as comprehensive as organic certifications found in all-natural mattresses.
Transportation and Packaging
Amerisleep has implemented innovative compression technology that allows them to fit three times more mattresses on delivery trucks compared to traditional mattress shipping.
This efficiency reduces transportation emissions significantly. Imagine reducing three delivery trucks to just one for the same number of mattresses.
Their U.S.-based manufacturing also means shorter shipping distances for American customers, further reducing the transportation carbon footprint.
Not the Best or Worst
Looking at the bigger picture, the AS3 represents a middle ground in terms of environmental impact.
While not as eco-friendly as all-natural alternatives, its combination of domestic manufacturing, reduced emissions, partially plant-based materials, and efficient shipping makes it more environmentally responsible than many traditional memory foam mattresses.
Understanding these factors helps consumers make informed decisions about balancing comfort needs with environmental considerations.
For those choosing the AS3, several strategies can help reduce its environmental footprint:
- Maximize the mattress’s lifespan through proper care and maintenance
- Use a quality mattress protector to prevent premature degradation
- Research local mattress recycling facilities for eventual disposal
And for those particularly concerned about environmental impact, it’s worth noting that Amerisleep offers their Organica line as a more sustainable alternative.
However, if the AS3’s specific features and feel are what you’re seeking, knowing its environmental impact can help you take steps to minimize its footprint while still enjoying its benefits.
Potential Drawbacks
After thoroughly testing the Amerisleep AS3, I want to share an honest assessment of its potential drawbacks. While I generally found this to be an excellent mattress, there are several limitations that potential buyers should carefully consider before making their purchase.
These possible issues, while noteworthy, should be weighed against the mattress’s many strengths and your specific sleep needs. In my experience, none of these drawbacks were deal-breakers, but they might be significant factors depending on your particular preferences and requirements.
Firmness Not for Everyone
The medium firmness level, while versatile, might not satisfy everyone’s preferences. During my testing, I noticed that when I was lying on my stomach, the mattress felt a bit too soft in this position. Specifically, I found my hips sinking slightly more than ideal for optimal spinal alignment.
While this may not be an issue for everyone, stomach sleepers who prefer a firmer surface should consider the Amerisleep AS2 instead.
Not Perfect Coolness
Temperature regulation, while generally good, isn’t perfect. During particularly warm nights, I noticed that despite the cooling cover and breathable Bio-Pur foam, heat could still build up somewhat after several hours. This was especially true when I didn’t move much during sleep.
While it performs better than traditional memory foam, it doesn’t provide the same level of cooling as some hybrid models with their superior airflow through coil systems.
May Not Fit All Budgets
Price point is another potential drawback. While I believe the quality justifies the cost, the AS3’s pricing puts it in a higher bracket than many bed-in-a-box competitors.
During my research and testing period, I found several comparable memory foam mattresses available for several hundred dollars less. Quite a few of which I’ve slept on before and would heartily recommend, like the Zoma Start or the original Vaya Mattress.
Though Amerisleep often runs promotions and offers financing that help offset this cost, the regular pricing might be prohibitive for budget-conscious shoppers.
Softer Edges
One of the most noticeable issues I encountered was with edge support, though I suspected this as it’s a pure foam mattress. While the mattress didn’t completely collapse under me, I found myself naturally shifting away from the edge to find more stable support.
For couples who frequently use the entire surface of the mattress, this could mean less usable sleeping space.
Bulky Weight
The weight of the mattress can also present some challenges. When I first set up the AS3 and later rotated it (which isn’t required but can promote even wear), I found it quite heavy and somewhat unwieldy to move, especially in larger sizes.
Now this isn’t unusual for a quality memory foam mattress, but it’s worth considering if you anticipate needing to move the mattress frequently.
Slight Smell
Finally, there’s the issue of the initial off-gassing period. While minimal compared to many memory foam mattresses I’ve tested, there was still a noticeable “new mattress” smell upon unboxing.
Though it dissipated within about 48 hours in my well-ventilated room, those sensitive to odors might find this initial period uncomfortable. I’d recommend letting the mattress air out in a spare room if possible before sleeping on it.
Mattress Policies and Prices
Consider that a mattress is one of the most frequently used pieces of furniture you’ll ever own. You’ll spend approximately one-third of your life on it.
This makes it essential to understand not just the upfront cost, but also what protections you have if something goes wrong, how long you have to test the mattress in your home, and what conditions might void your warranty.
For example, using the wrong type of foundation could invalidate your warranty coverage, potentially leaving you without protection for a significant investment.
Moreover, understanding pricing in the context of the broader mattress market helps you make an informed decision about value. While two mattresses might seem similar at first glance, their warranty terms, trial periods, and long-term durability can make a significant difference in their true cost over time.
A mattress that costs more upfront but lasts longer and has better warranty coverage might actually be more economical than a cheaper option that needs replacement sooner.
And one of the most striking aspects of Amerisleep’s policies is their extended 20-year warranty (double the industry standard of 10 years) which demonstrates their confidence in their product’s durability.
They also offer a thoughtfully structured 100-night sleep trial that gives you ample time to adjust to the mattress and determine if it’s right for you.
Mattress Warranty
A warranty matters because your mattress is a significant investment that affects your sleep and health every night. Having a strong warranty shows that Amerisleep believes in their product’s quality and gives you protection against manufacturing defects or premature wear.
It means you won’t have to pay full price for a replacement if something goes wrong that isn’t your fault. Think of it as insurance for your sleep investment.
The AS3 comes with a 20-year warranty, divided into two phases:
During the first 10 years, Amerisleep will replace your mattress completely if it develops qualifying problems. These include manufacturing defects like cracks in the foam, or if your mattress gets a permanent depression deeper than 1.5 inches where you sleep (not counting the edges or corners).
During this initial period, you get the replacement mattress free, though you might need to pay for shipping.
In the second 10 years, you still have protection, but it works differently. If you need a replacement during this time, you’ll pay 50% of what your original AS3 cost, plus any shipping expenses.
To keep your warranty valid, you need to follow certain rules:
- Never remove the law tag from your mattress
- Keep your mattress free from stains (using a mattress protector is recommended)
- Use proper support under your mattress – either a platform bed, adjustable base, or solid foundation
- If you want to use a box spring, you must put a piece of moisture-resistant plywood at least 3/4 inch thick on top of it
If you ever need to make a warranty claim, you’ll need to show your original purchase receipt. Amerisleep might also ask for photos of your mattress and its foundation to verify the problem.
One crucial detail: this warranty only applies to the original purchaser. If you give away or sell your AS3, the new owner won’t be covered by the warranty – they get the mattress “as is.”
Unlike many products with shorter warranties, a 20-year warranty means Amerisleep expects their AS3 to last for a long time.
This long coverage period helps protect your investment and ensures you can sleep confidently knowing you’re covered if something goes wrong with your mattress.
Mattress Sleep Trial
A sleep trial matters because choosing a mattress is a very personal decision. What works perfectly for one person simply might not work for another.
Unlike testing a mattress for a few minutes in a store, a sleep trial lets you experience the mattress in your own home, with your normal sleep habits, over many nights. This gives you a true sense of whether the mattress is right for you.
Your trial period starts when your mattress arrives at your home. If you also ordered an adjustable bed base with your mattress, the trial won’t start until both items arrive. This ensures you get a full 100 nights to test the complete sleep setup.
While many people love their AS3 from the first night, Amerisleep notes that it can take up to 30 nights for your body to fully adjust to a new mattress. This is normal. So if you experience minor aches or stiffness at first, it’s often just your body adapting to proper support.
If you decide the AS3 isn’t right for you, you can return it for a full refund, but there’s one important requirement: you need to try the mattress for at least 30 nights before starting a return. This minimum trial period ensures you’ve given your body enough time to adjust to the new mattress.
If you want to return the mattress, just contact Amerisleep within the 100-night period. They make the return process simple:
- You’ll work with their Arizona-based support team
- They’ll arrange free pickup of the mattress
- Once the return is complete, they’ll process your refund
This risk-free trial period means you can try the AS3 in your own home with confidence, knowing you have plenty of time to make sure it’s the right mattress for you.
It removes the pressure of making a quick decision and ensures you only keep the mattress if it truly gives you great sleep.
Mattress Sizes and Prices
The Amerisleep AS3 is made in the standard seven mattress sizes. Remember that when choosing a mattress size, you should consider not just the sleeping space needed, but also your room dimensions, allowing at least 2 feet of clearance around three sides of the bed for comfortable movement and making the bed.
Mattress Size | Mattress Sales Price |
---|---|
Twin | $999 |
Twin XL | $1049 |
Full | $1199 |
Queen | $1249 |
King | $1549 |
California King | $1549 |
Split King | $2148 |
When we compare this to similar memory foam mattresses, we can see how it stacks up. For example, the Nectar, Zoma, Vaya, Brooklyn Bedding, all direct competitors, may have models less expensive than the AS3.
However, it’s important to understand that the AS3 uses more advanced materials, particularly its plant-based Bio-Pur foam and specialized HIVE technology, which helps justify its higher price point.
Moving up the price scale, we find premium competitors like Tempur-Pedic or Saavta, whose comparable models often cost significantly more, making the AS3 appear quite reasonable in comparison. This puts the AS3 in an interesting middle ground, offering premium features at a more accessible price point.
Looking at other popular direct-to-consumer brands, we see also that Amerisleep is right in line with brands like Purple or Casper. As these are major competitors, suggesting its pricing is quite competitive within its market segment.
When evaluating the price point, several factors should be considered:
- The durability of the materials suggests a longer lifespan than less expensive alternatives
- The warranty length (20 years) is double the industry standard
- The inclusion of free shipping and returns
- The 100-night trial period
- The eco-friendly materials and manufacturing processes
Amerisleep often offers bundle deals that can provide significant savings when purchasing a complete sleep system. For example, adding a frame to an AS3 purchase can save up to 40% on the base. These bundle options are competitive with similar offerings from other premium mattress brands.
Amerisleep offers financing through Klarna, with payments as low as $70 per month for the AS3, making the premium price point more accessible. This is comparable to financing options offered by competitors, though interest rates and terms can vary based on credit approval.
Customer Reviews
Reviews help establish performance expectations over time. While a mattress might feel comfortable in a showroom for a few minutes, these reviews from customers tell us how it holds up after months or years of use.
When people spend significant time with a product like a mattress, they discover aspects of its performance that only become apparent through extended use.
And the Amerisleep AS3 mattress has received overwhelmingly positive feedback, with particular praise for its comfort, durability, and pain-relieving properties.
The majority of reviewers highlight how the mattress provides an ideal balance between softness and support, making it suitable for different sleeping positions.
Many customers specifically mention improvements in their back pain after switching to the AS3.
For example, Jones from Saint Paul, MN, who has undergone seven back surgeries, reported that their “body loves this mattress.” Similarly, Shelby from Northern Michigan noted significant improvement in their hip bursitis and lower back pain: “Minimal hip and back pain when I wake up now. Soft, but I still feel supported.”
The mattress’s temperature regulation features have also received positive attention. Kate from Brooklyn, NY, provided detailed feedback about the cooling properties, noting that even though she experiences menopausal night sweats, she “can’t imagine how much worse it would be without” the cooling feature.
Multiple reviewers also appreciate the motion isolation properties, with CWC from New Jersey mentioning that “the excellent motion isolation means I stay asleep even when the kids sneak into bed.”
Long-term durability appears to be a strong point for the AS3. Several customers have reported sustained performance over multiple years.
JR from Bothell, WA shared that after three years, “it’s held its shape, does not make you hot like others do and I no longer toss and turn because of being uncomfortable.”
Some customers, like Flip from Postfalls, ID, even kept their previous Amerisleep mattress for alternative use, noting that after 12 years, it “still is very comfortable and is not sagging.”
However, there were some mixed reviews regarding the firmness level. While most found it comfortable, a few customers like Ricardo from New York felt it was “too soft and has little motion isolation.”
Cynthia from Gretna, LA mentioned it was “a little harder than expected” but appreciated that the company sent a topper to help make it softer.
The customer service experience has also been notably positive, with many reviewers commenting on the company’s responsiveness and willingness to address concerns.
Dave C from San Diego shared a particularly touching story about purchasing the mattress for his 86-year-old mother, reporting that “she can’t remember when she last slept this well.”
Many customers have become repeat buyers, indicating high satisfaction levels. Virginia from Illinois expressed regret at not making the purchase sooner: “Why did it take us so long? … I will sing the praises of this mattress forever.”
The sentiment is echoed by numerous reviewers who mention purchasing additional AS3 mattresses for guest rooms or vacation homes after experiencing the comfort of their first one.
Mattress Care and Maintenance
When it comes to mattress care, understanding what not to do is just as important as knowing the proper maintenance steps. As someone who has tested numerous mattresses and seen the consequences of common care mistakes, I want to share critical guidance on protecting your AS3 investment.
While the AS3 is designed to be low-maintenance, a little care goes a long way. Certain actions or oversights can significantly reduce its lifespan or even void your warranty. Like how regular oil changes protect your car’s engine, avoiding these mistakes will help ensure your mattress maintains its comfort and support for years to come.
Protecting Against Stains
For spill protection, I suggest investing in a high-quality waterproof mattress protector specifically designed for memory foam mattresses. I also strongly recommend putting this protector on immediately after unboxing the mattress, to best maintain its pristine condition.
This advice has proven invaluable to me as a mattress owner and frequent tester. Not only does a protector guard against accidents, but it also helps prevent sweat and body oils from seeping into the foam while still allowing the cooling properties to function effectively.
I make sure to wash the protector regularly, about every three weeks, to maintain its protective qualities.
Whenever I’ve needed to address small stains, I’ve had success using a gentle mix of mild detergent and cool water, carefully blotting the area rather than rubbing it to clean the mattress.
This method has worked well for me without compromising the mattress’s performance. It’s crucial to avoid over-saturating the mattress.
Regular Rotation
One aspect I particularly appreciate about the AS3 is that it doesn’t require flipping or rotating like traditional mattresses. However, I still rotate mine 180 degrees every three to six months.
This practice helps ensure even wear, especially since I tend to sleep on one side of the bed more than the other. I’ve noticed this routine helps maintain consistent comfort across the entire surface.
Have Proper Mattress Support
One thing I learned through experience is the importance of proper support. I originally had the very first memory foam mattress I ever owned on an old bed frame with widely spaced slats, which wasn’t ideal. It was quick to develop saggy spots within a couple of years
After switching to a platform bed with slats no more than 3 inches apart, I noticed improved support and performance from the mattress. This adjustment made a noticeable difference in how the mattress felt and responded to movement.
Eliminating Smells
When it comes to addressing odors, I’ve found that a light sprinkling of baking soda works wonders. I leave it on for several hours (usually while I’m at work), then vacuum it thoroughly. This natural deodorizing method has helped maintain freshness without introducing harsh chemicals that could potentially damage the foam.
Speaking of, I discovered early on as a tester that vacuum cleaning is essential for keeping a memory foam mattress like the AS3 fresh. Every couple of weeks, I use my vacuum’s upholstery attachment to gently clean the surface.
I pay special attention to the seams and crevices where dust tends to accumulate. This regular maintenance has helped maintain the mattress’s pristine condition and keeps allergens at bay. I’ve found that doing this in the morning allows any displaced dust to settle before bedtime.
Things Not to Do
Never remove the law tag from your mattress, as this can void your warranty. Think of this tag as your mattress’s birth certificate. And without it, you might struggle to make warranty claims.
Avoid using harsh cleaning chemicals or steam cleaners on your AS3. I’ve seen how these can break down the foam structure and potentially release harmful fumes. Instead, stick to gentle spot cleaning with mild detergent when necessary.
Don’t place your mattress directly on the floor or on a box spring without proper support. The Bio-Pur foam requires consistent, even support to maintain its integrity. I learned this lesson firsthand when I temporarily placed a memory foam mattress on the floor and noticed it quickly developed uneven spots.
Never stand, jump, or kneel on your AS3. While it might seem sturdy enough, concentrated pressure in small areas can damage the foam structure. I’ve examined mattresses with permanent indentations from this type of misuse.
Avoid using electric blankets or heating pads at high temperatures. The heat can affect the foam’s molecular structure, potentially changing its responsiveness and support characteristics. I’ve tested mattresses where prolonged heat exposure noticeably altered the foam’s performance.
Don’t expose your AS3 to direct sunlight for extended periods. UV rays and heat can degrade the foam and fade the cover material. In my testing facility, I’ve observed how mattresses stored near windows can develop uneven wear patterns.
Never bend or fold your mattress, as this can damage the internal structure. When moving the mattress, always keep it flat or carefully on its side. During my evaluations, I’ve seen how improper handling can create permanent creases in the foam.
Frequently Asked Questions
The Amerisleep AS3 is designed with a medium firmness level (around 5-6 out of 10) that accommodates a wide range of sleepers, making it particularly well-suited for average-weight individuals between 130-230 pounds.
However, very lightweight sleepers under 130 pounds might find it slightly too firm, while those over 230 pounds may experience too much sinking, especially around the hips and shoulders.
For these sleepers, Amerisleep offers alternatives like the softer AS5 for petite individuals or the firmer AS2 for heavier sleepers.
The choice depends largely on your specific needs and preferences, with each version offering distinct advantages. The all-foam AS3 excels in motion isolation and pressure relief, making it ideal for couples and those who prefer a more conforming feel.
The hybrid version, with its pocketed coil support core, provides better edge support and airflow, while offering more bounce and responsiveness. These are qualities that benefit combination sleepers and those who run hot during sleep, though it comes at a higher price point.
While technically you can sleep on the Amerisleep AS3 shortly after unboxing, it’s better to allow some time for the mattress to fully expand and any potential off-gassing odors to dissipate.
The mattress typically needs 24 to 48 hours to reach its full height and optimal comfort level, though any initial off-gassing smell usually dissipates within a few hours thanks to the plant-based Bio-Pur foam.
The waiting period ensures you’ll experience the mattress as intended and helps prevent any potential compression issues that might occur from immediate use.
The Amerisleep AS3 is indeed non-toxic and completely free of fiberglass, using CertiPUR-US certified foams that are tested for harmful chemicals and emissions.
The mattress incorporates plant-based Bio-Pur foam, which replaces a portion of petroleum-based materials with sustainable plant oils, resulting in lower VOC emissions and a cleaner sleep environment.
Additionally, Amerisleep’s manufacturing process produces zero emissions, further demonstrating their commitment to both environmental and human health.
The Amerisleep AS3 is particularly well-suited for side sleeping due to its strategic combination of pressure relief and support features.
The Bio-Pur comfort layer provides enough cushioning to allow shoulders and hips to sink in appropriately, while the HIVE transition layer offers targeted support zones that help maintain proper spinal alignment.
The medium firmness level strikes an excellent balance between conforming comfort and support, though very petite side sleepers might prefer the softer AS5 models for additional pressure relief.
The Amerisleep AS3 can indeed help alleviate back pain through its combination of supportive features and pressure-relieving properties, though individual results may vary depending on the specific cause and nature of the pain.
The HIVE technology in the transition layer creates targeted support zones that help maintain proper spinal alignment, while the Bio-Pur foam contours to the body to reduce pressure points.
However, for those with chronic lower back pain, the slightly firmer AS2 model might be more beneficial as it offers enhanced lumbar support and less sinking in the hip area.
The Amerisleep AS3 does not require a traditional box spring, and in fact, using one could potentially compromise the mattress’s performance and void its warranty.
Instead, the mattress performs best on a solid platform bed, adjustable base, or slatted bed frame where the slats are no more than 3 inches apart to provide adequate support.
This proper foundation ensures optimal performance of the mattress’s support layers and helps maintain its durability over time.
Closing Thoughts
After putting the Amerisleep AS3 through its paces like a marathon runner training for race day, I can confidently award it a stellar 9 out of 10. I would say it’s like getting an A- on your report card. It’s not quite perfect, but definitely something to brag about to your friends.
This mattress hits the sweet spot like a perfectly toasted marshmallow, just the right balance of squish and support. Sure, it has a few minor quirks (those edges could be firmer, and it’s not exactly light as a feather when you need to move it), but these are small wrinkles in an otherwise smooth sleeping experience.
The Bio-Pur foam and cooling technology work together like Batman and Robin to keep you comfortable all night long.
At this price point, you’re getting a lot of bang for your buck, kind of like finding a designer jacket at an outlet store. The 20-year warranty alone is worth its weight in gold, or at least in memory foam.
