Freshly Re-evaluated

We've recently updated our top mattress picks, incorporating new insights from our professional testers. If a mattress appears on this list, you can be sure that we've personally assessed it and granted it a high rating based on our stringent evaluation standards.

During my testing period of the Amerisleep AS5, I deliberately pushed this mattress to its limits: sleeping in every position imaginable, conducting targeted pressure tests, and even staging marathon weekend lounging sessions to evaluate its long-term comfort.

And so I’ve developed a detailed understanding of who this mattress might suit best and where it could fall short. I also analyzed hundreds of customer reviews to understand how the mattress performs over years of use, not just weeks of testing.

What emerged from this thorough evaluation was a picture of a mattress that excels in some areas while showing limitations in others. For side sleepers seeking plush comfort without the quicksand feel of traditional memory foam, the AS5 offers some compelling innovations.

However, its ultra-soft design and premium price point mean it isn’t for everyone. Let’s dive deep into every aspect of this mattress (from its sophisticated layering system to its environmental impact) so you can decide if it might be your perfect match for better sleep.

Whether you’re specifically interested in the AS5 or just beginning your mattress research journey, this detailed review will help you understand what makes a quality mattress and how to evaluate whether a particular model aligns with your needs.

After all, we spend roughly a third of our lives in bed. Shouldn’t we make that time as comfortable as possible?

Mattress Layers, Materials, and Construction

Unboxing the Amerisleep AS5, I watched as it swiftly rose into shape. As I did so, I noticed only a minimal “new mattress” smell that dissipated quickly. This is a noticeable improvement over traditional memory foam mattresses I’ve tested.

And having tested many mattresses, I pay particular attention to how different layers work together and what makes each component unique.

The overall 14-inch profile is substantial, and during my testing, this extra height provided ample depth for the comfort layers to work effectively. I noticed that even as a side sleeper, I never “bottomed out” or felt the firmer base layer, regardless of my sleeping position.

This thoughtful layering system also explains some of the mattress’s impressive performance characteristics I observed. For instance, the motion isolation capabilities – which I tested extensively – result from how these layers work together to absorb and dampen movement. Each time I conducted motion transfer tests, I could feel how the various foam layers absorbed energy rather than transferring it across the mattress surface.

Mattress Cover

Starting from the top, the first thing I noticed was the Refresh Cooling Cover. When I touched it, I was struck by its immediate cool sensation. Calling its feel “refreshing” is not just marketing speak.

See, the cover uses specialized fibers that actively convert body heat into infrared energy. While this might sound like high-tech jargon, I could genuinely feel the difference compared to standard mattress covers. Even after lying in one spot for an extended period, the surface maintained its cool-to-the-touch feel.

Comfort Foams

Just beneath the cover, I encountered the Bio-Pur® memory foam layer. This is where Amerisleep’s innovation really shines through. As someone who’s worked with many types of memory foam, I immediately noticed how this plant-based foam differs from traditional petroleum-based versions.

When I pressed my hand into it, the foam responded quickly—both conforming to pressure and bouncing back much faster than typical memory foam. The open-cell structure became apparent during my temperature testing; I could feel how it allowed for better airflow compared to the denser structure of conventional memory foam.

Not to mention I appreciated Amerisleep’s commitment to eco-friendly materials. The Bio-Pur® foam not only performs well but also produces fewer off-gassing odors.

Next up is the Active Flex layer. It is a unique component that I haven’t seen in many other mattresses, and the foam;s feel particularly impressed me during my testing.

When I shifted positions, I could feel how this layer provided an immediate response while maintaining the plush feel of the top layer. It’s like having a bounce-back buffer between the soft comfort layers and firmer support beneath.

This creates what I’d describe as a “floating” sensation rather than the “sinking” feel often associated with soft mattresses.

Transition Foam

Moving deeper into the mattress, I examined the HIVE® transition layer (which stands for Harnessing Intelligent Ventilation & Energy). This layer fascinated me with its precision engineering.

When I looked closely at a foam sample, I could see the hexagonal cutouts create different support zones. Lying on the mattress, I noticed how these zones provided targeted support – softer under my shoulders and hips, firmer under my lower back and legs.

During my testing, this zoned support became particularly apparent when sleeping on my side, as the shoulder area allowed for more give while maintaining spinal alignment.

Base Foam

The foundation of the AS5 is the Bio-Core® base layer, and its importance shouldn’t be underestimated. When I pressed firmly into the mattress, I could feel how this high-density foam provides the structural support that prevents sagging.

It’s notably firmer than the upper layers, which explains why even this ultra-soft mattress maintains its shape and support over time. Yet when I moved around on the mattress, I could feel how each layer contributed to the overall sleep experience. The transition from the plush top layers to the supportive base felt seamless rather than abrupt.

Sleep Positions

How a mattress performs in various positions is essential because even if you have a preferred sleeping position, most people move throughout the night. Plus, what feels comfortable in one position might create pressure or alignment issues in another.

In my testing methodology, I spent extended periods in each position, systematically evaluating factors like spinal alignment, pressure relief, ease of movement, and overall comfort.

I conducted specific tests for each position, including pressure point checks, alignment assessments, and what I call a “sleep cycle test” for combination sleeping.

This thorough approach helps reveal not just immediate comfort but also how the mattress might affect your body over a full night’s sleep.

What I discovered through this testing was that the AS5’s ultra-soft design creates notably different experiences depending on your sleeping position. While it excels magnificently in some positions, it presents clear limitations in others.

Let me break down exactly what I found in each position, and explain why these differences matter for your sleep quality.

Side Sleeping

When I first lay on my side on the AS5, I immediately noticed how the plush top layers allowed my shoulder and hip to sink in appropriately. This is crucial for side sleeping, as these pressure points need adequate cushioning to prevent pain and numbness.

I spent several hours testing it as a mattress for side sleeping, periodically checking my spinal alignment and pressure relief. What impressed me most was how the mattress managed to cradle my shoulder without creating that uncomfortable pinched feeling I often experience on firmer mattresses.

The Bio-Pur® foam and Active Flex layer worked together to create a gentle cradle effect. I could feel my body sinking in just enough to maintain proper spinal alignment while still feeling supported.

To thoroughly test pressure relief, I remained in one side position for an extended period (about an hour) and monitored for any pressure build-up or discomfort. I paid particular attention to my shoulder and hip areas, as these are common problem spots for side sleepers.

Even after this extended period, I didn’t experience any of the usual pressure points that often force me to change positions.

I also tested side sleeping near the edge of the mattress since couples often need to utilize the entire surface. While there was slightly more compression at the edges, I still felt secure and well-supported, though not quite as stable as in the center of the mattress.

Back Sleeping

Back Sleeping

Switching to back sleeping showed me that the AS5’s ultra-soft design could still be limited in its comfort. When lying on my back, I noticed that my hips sank deeper into the mattress than my shoulders, creating a slight hammocking effect. This matches what several reviewers noted about spinal alignment in this position.

To test this thoroughly, I placed a hand beneath my lower back to check the gap – ideally, there should be just enough space to slide your hand through. With the AS5, I found this space was slightly compromised due to the softer feel allowing my hips to sink too deeply.

After about 30 minutes of back sleeping, I began to feel some strain in my lower back, suggesting this might not be ideal for dedicated back sleepers.

However, I should note that my experience aligns with what lighter-weight reviewers reported – they often found back sleeping more comfortable than I did. This makes sense, as less body weight would result in less sinking at the hips.

During my back-sleeping tests, I also evaluated how easy it was to change positions. Despite the mattress’s softness, the Active Flex layer prevented that “stuck” feeling that often plagues soft memory foam mattresses. I could transition from my back to my side without feeling like I was fighting against the mattress.

Stomach Sleeping

Testing the AS5 for stomach sleeping, I immediately noticed some concerning issues. As I settled onto my stomach, I could feel my midsection sinking noticeably deeper than the rest of my body. The ultra-soft nature of the mattress, which works so well for side sleeping, created an exaggerated arch in my lower back that began causing discomfort within minutes.

To thoroughly evaluate this position, I conducted several specific tests. First, I placed my palm under my stomach to check the depth of sinking – it was substantial enough that I could easily slide my entire hand into the gap created between my body and the mattress. This indicated excessive dipping that could lead to spinal misalignment.

After about 15 minutes of stomach sleeping, I began feeling strain in my neck and lower back. By 30 minutes, the discomfort was significant enough that I had to change positions. When I sat up after this test, I noticed some stiffness in my lower back that took several minutes to dissipate.

I also tested different variations of stomach sleeping—with and without a pillow, arms at different positions.

But the fundamental issue remained: the mattress was simply too soft to maintain proper spinal alignment in this position. I would not recommend it for primary stomach sleepers.

Combination Sleeping

To test combination sleeping thoroughly, I performed what I call a “sleep cycle test” – deliberately changing positions every 15 minutes for two hours to simulate a night of active sleeping.

The mattress performed quite differently depending on which positions I was switching between. Let me break this down by transition types:

• Side-to-Back Transitions: These movements felt relatively smooth. The Active Flex layer helped prevent that “stuck” feeling common in soft memory foam mattresses, allowing me to roll from my side to my back without much effort. However, once on my back, I did notice the less-than-ideal support mentioned in my back sleeping tests.
• Back-to-Side Transitions: These were perhaps the most comfortable transitions. The plush upper layers made it easy to settle into a side-sleeping position, and the responsiveness of the Bio-Pur® foam meant I didn’t have to wait for the mattress to adapt to my new position.
• Any Transitions Involving Stomach Sleeping: These proved more challenging. When rolling to or from my stomach, I found myself having to make more deliberate movements to compensate for the excessive softness. The mattress’s plush nature meant I had to use more energy to maintain proper alignment during these transitions.

I noticed that while the mattress responded well to movement, the varying comfort levels in different positions meant I naturally avoided stomach sleeping and spent less time on my back.

The edge support also played a role in combination sleeping. When my position changes brought me near the edge of the mattress, I could feel a slight decrease in support, though not enough to make me feel unstable.

Mattress Responsiveness

Responsiveness refers to how quickly a mattress adapts to changes in pressure and movement. Think of it like this: when you move from your back to your side, you want the mattress to quickly adjust to your new position rather than leaving you feeling stuck or fighting against the material.

High responsiveness contributes to a mattress’s overall comfort and support. When you change positions during sleep, you want your mattress to quickly conform to your new position to maintain proper spinal alignment. A feature that is particularly important for combination sleepers who change positions frequently during the night.

Throughout my nights of testing, I found that the AS5 consistently provided this adaptive support, helping maintain comfort regardless of my sleeping position. After extensive testing, I’ve given the it an 8 out of 10—let me explain why.

To thoroughly evaluate the AS5’s responsiveness, I conducted several specific tests. First, I performed what I call the “press test.” As might be evident, this is me pressing my hand firmly into different areas of the mattress and timing how quickly it regained its shape.

The Bio-Pur® foam impressed me here, bouncing back almost immediately after I removed my hand. Unlike traditional memory foam that often leaves a lingering handprint, the AS5’s surface recovered within seconds.

Next, I conducted a series of movement tests. I rolled from my back to my side, then to my stomach, paying close attention to how the mattress adapted to each new position.

What stood out was how the Active Flex layer worked in concert with the Bio-Pur® foam. Instead of feeling trapped in one position, I could shift smoothly between positions without that “quicksand” feeling often associated with memory foam.

I also performed what I call the “quick movement test,” deliberately making sudden movements like quickly sitting up or flopping onto the bed. The mattress responded swiftly to these abrupt changes, providing consistent support without any noticeable lag time.

To quantify the response time more precisely, I used a weighted ball test. I dropped a 10-pound weight onto the mattress and observed its bounce response. The ball bounced slightly before settling, indicating good energy return without excessive springiness—exactly what you want for easy movement without disrupting sleep.

The reason I’ve given it an 8 rather than a perfect 10 is that there’s still a slight delay compared to what you’d find in latex or traditional spring mattresses.

This isn’t necessarily a negative. In fact, many sleepers prefer this subtle conforming quality. But it’s worth noting for those who prioritize maximum responsiveness.

This balance became especially apparent during my partner disturbance tests. When my partner and I took turns moving around, we found that the mattress responded quickly to our movements without transferring much motion to the other person. This is a rare combination that makes it particularly suitable for couples.

Still, it’s good to know that this is one area where a higher score isn’t necessarily better, as comfort is subjective and some will find an 8 is their perfect 10.

For those considering the AS5, this level of responsiveness means you’ll likely find it easy to move around and get comfortable, while still enjoying the pressure-relieving benefits of memory foam. It’s a particularly good balance for combination sleepers who want the comfort of a soft mattress without feeling restricted in their movement.

Mattress Motion Isolation

Motion isolation is crucial because it determines how well a mattress prevents movement on one side from disturbing someone sleeping on the other. It’s a make-or-break feature for couples, especially if one person is a light sleeper or has a different schedule.

It’s a feature I always examine seriously, and after some practiced tossing and turning, I would give the AS5 a notable 10 out of 10.

To thoroughly evaluate this feature, I conducted several practical tests. First, I used what I call the “water glass test.” I placed a glass of water filled nearly to the brim on one side of the mattress, then deliberately moved around on the other side.

Even with exaggerated movements like getting in and out of bed or changing positions abruptly with a flop, the water surface barely rippled. This is particularly impressive for any mattress, let alone one with the AS5’s soft, responsive feel.

Next, I conducted partner testing. My partner and I took turns moving while the other lay still with eyes closed, trying to detect movement. We went through a series of real-world scenarios: tossing and turning, getting up for a midnight bathroom visit, and even sitting heavily on the edge of the bed. The results were remarkable – neither of us could perceive the other’s movements unless we were deliberately trying to feel them.

To quantify the motion isolation more precisely, I performed my weighted impact test. I dropped a 10-pound weight from about a foot above the mattress surface while my partner lay on the other side. The mattress absorbed the impact impressively, with my partner reporting only the slightest awareness of the disturbance.

What particularly impressed me was how the AS5 achieved this level of motion isolation while maintaining its responsive feel. Typically, mattresses that excel at motion isolation can feel deadened or sluggish, but the AS5’s Bio-Pur® foam and Active Flex layer managed to strike a perfect balance between motion absorption and responsiveness.

The perfect score is justified by how well these layers work together to prevent motion transfer. The Bio-Pur® foam’s quick response time combined with the transitional layers creates an effective buffer zone that stops movement at its source before it can ripple across the mattress surface.

For couples, particularly those with different schedules or sleeping habits, this exceptional motion isolation means one partner can move freely without worrying about disturbing the other’s sleep. It’s a feature that might seem minor when shopping but can significantly impact your daily sleep quality, especially in long-term use.

Mattress Edge Support

I’m giving the AS5’s edge support an 8 out of 10. This is largely due to the plush nature of the mattress rather than any structural weakness. The support comes from the high-density Bio-Core® base layer, which extends right to the edges and provides a sturdy foundation throughout the mattress’s perimeter.

To thoroughly evaluate the AS5’s edge support, I conducted several systematic tests. First, I sat directly on the edge in different positions—both with my feet planted on the floor and with my legs extended on the bed. The mattress compressed under my weight, as expected from an ultra-soft model, but I never felt unstable or like I was going to slip off.

Next, I performed what I call the “stand-up test.” Starting from a seated position on the edge, I pushed off to stand up, paying attention to how much support the edge provided.

The AS5 offered a stable base that made this transition smooth and controlled. This is particularly noteworthy for a soft mattress, as many plush models tend to compress too much during this movement.

I also tested the edges while lying down. I deliberately positioned myself right at the edge of the mattress, gradually moving closer until I was nearly at the perimeter.

Even in this precarious position, I felt surprisingly secure. The edge maintained its integrity well, though there was some expected compression given the mattress’s soft nature.

Finally, I examined the corners, often the weakest points in a mattress’s edge support system. The corners held up well under pressure, showing only slightly more give than the straight edges.

This level of edge support is particularly impressive when you consider that most ultra-soft mattresses struggle in this area. The AS5 manages to maintain its supportive structure while still delivering the cloud-like comfort that side sleepers and those seeking a plush feel desire.

Yes, there is still some noticeable compression when sitting directly on the edge. But for couples sharing a bed or anyone who likes to use the full surface of their mattress, this means you can comfortably use the entire sleeping surface without feeling like you might roll off.

Coolness and Breathability

Temperature regulation matters immensely for sleep quality. See, our bodies naturally need to cool down to initiate and maintain restful sleep.

So a mattress that traps heat can disrupt this process, leading to restless nights and poor sleep quality. This is particularly crucial for memory foam mattresses, which traditionally tend to retain heat.

It’s an aspect I like to examine thoroughly, testing through varying room temperatures and humidity levels. And the AS5 performed consistently well in all conditions. Even in warmer temperatures, the mattress maintained its cooling properties, which is why I feel confident giving it a perfect 10/10 score.

My testing approach was practical and real-world focused. First, I noted my immediate sensation when lying on the mattress.

The Refresh Cover lives up to its name here. It felt noticeably cool to the touch, even after I had been lying in the same spot for 30 minutes. This isn’t just a surface-level effect; the coolness persisted throughout my sleep sessions.

To really stress test the cooling capabilities, I conducted what I call the “heat retention test.” I deliberately raised my body temperature through light exercise right before bed, then lay on the mattress without any covers.

I was impressed by how quickly the mattress helped dissipate my excess body heat. Unlike many memory foam mattresses that seem to reflect heat back to your body, the AS5’s Bio-Pur® foam allowed the heat to disperse effectively.

I also performed extended testing sessions, deliberately staying in one position for long periods (up to an hour) to check for heat buildup.

Even after lying still on my back for this extended time, I didn’t experience that uncomfortable “hot spot” sensation that’s common with traditional memory foam. The open-cell structure of the Bio-Pur® foam seems to allow for significantly better airflow than typical memory foam.

Weekend testing proved particularly revealing. On days when I could lounge in bed for extended periods (sometimes up to 10 hours), I paid careful attention to temperature regulation.

And even during these marathon sessions, I never experienced the heat accumulation that typically forces you to shift positions or flip your pillow to the “cool side.”

What really sets the AS5 apart is how it maintains its cooling properties under different conditions. I tested it with various bedding combinations—lightweight sheets, heavy comforters, and multiple pillow configurations.

The mattress maintained its temperature-neutral feel regardless of the bedding used. This versatility is particularly impressive and practical for year-round comfort.

The effectiveness of the cooling technology is also evident in the customer reviews. Because out of over 500 reviews, only two mentioned heat retention as an issue. This remarkably low number for a memory foam mattress supports my perfect score.

For anyone who sleeps hot or has avoided memory foam mattresses due to heat concerns, the AS5’s exceptional temperature regulation could be a game-changer. It combines the pressure-relieving benefits of memory foam with cooling technology that actually works, making it an excellent choice for those who prioritize temperature regulation in their sleep environment.

Remember, the ability to maintain a comfortable temperature throughout the night isn’t just about comfort. It’s fundamental to achieving quality sleep. In this crucial aspect, the AS5 delivers outstanding performance that justifies its perfect score.

Material Durability and Mattress Longevity

From my hands-on testing, the AS5’s construction suggests promising durability markers.  And I would venture that most users should expect 7-10 years of good performance with proper care and maintenance, though individual experiences may vary based on factors like body weight, usage patterns, and environmental conditions.

However, I should note that my testing period can’t fully replicate years of nightly use. While I conducted intensive tests like repeatedly rolling across the mattress and conducting extended pressure tests in single positions, these simulations have limitations.

This is where user reviews become particularly valuable. Especially those from verified long-term owners.

One particularly telling review came from Andrea in PA, who reported that after almost 5 years of use by two adults and two dogs, their AS5 was “still fantastic and the best one I have owned… still holding shape with no sagging or loss of shape.”

Reviews like this help validate the durability promises suggested by the mattress’s construction.

The materials used in the AS5 offer some specific insights into how long the mattress lasts. The Bio-Pur® foam’s advanced open-cell structure appears more resilient than traditional memory foam.

I observed it consistently returning to shape more quickly than conventional memory foam, suggesting better resistance to permanent impressions. The material also seems to resist moisture and heat buildup, factors that can accelerate foam degradation over time.

The Active Flex layer adds another dimension to durability considerations. This responsive foam layer helps distribute weight more evenly, which should theoretically reduce the formation of body impressions over time.

The high-density Bio-Core® base layer provides robust structural support. When I pressed firmly into different areas of the mattress, I could feel this foundation maintaining its integrity even under substantial pressure. This base layer plays a crucial role in preventing the sagging that often plagues softer mattresses.

It’s worth noting that the AS5’s ultra-soft design could potentially impact its longevity. Softer foams typically compress more during use, which can lead to faster wear.

However, Amerisleep appears to have addressed this through their layering system. The transition from soft comfort layers to the firm support core felt seamless in my testing, suggesting the softer upper layers are well-supported to maintain their integrity.

The 20-year warranty provides some assurance of longevity, particularly the full replacement coverage for the first decade if deep indentations develop. However, I should note that warranty terms don’t necessarily predict actual performance. They’re more of a safety net than a guarantee.

Temperature regulation capabilities also factor into longevity. Excessive heat can break down foam over time, but the AS5’s cooling features seem to manage this risk well.

Though, throughout my temperature testing, I noticed consistent heat dissipation, suggesting the mattress should resist heat-related degradation better than traditional memory foam.

Environmental Impact

For those prioritizing environmental impact in their mattress purchase, the AS5 represents a middle ground. While it incorporates some eco-friendly features like plant-based materials and efficient shipping, it’s not as environmentally conscious as fully natural options like Amerisleep’s own Organica mattress.

Consider it a compromise between traditional memory foam mattresses and purely organic alternatives. This is better than conventional options but with clear room for improvement in areas like end-of-life recyclability and transparency about material sourcing.

If you do choose the AS5, you can minimize its environmental impact through proper care and maintenance to maximize its lifespan, using a mattress protector to prevent premature replacement, and researching local mattress recycling options for eventual disposal.

While it may not be the most environmentally friendly mattress available, it represents a step toward more sustainable practices in the memory foam mattress industry.

Plant-Based Memory Foam

The mattress’s environmental story starts with its signature Bio-Pur® foam. This material represents Amerisleep’s attempt to reduce reliance on petroleum-based chemicals by incorporating plant-based oils, specifically castor oil derivatives.

While this is certainly a step in the right direction, we should understand its limitations. Amerisleep doesn’t disclose the exact percentage of plant-based materials used, making it difficult to quantify the environmental benefit.

Think of it as replacing some of your car trips with bicycle rides. It’s better than driving everywhere, but not quite the same as going completely car-free.

Still I do applaud the effort to improve upon a material that’s traditionally all synthetic.

The foams are also CertiPUR-US® certified, meaning they’re made without ozone depleters, certain harmful flame retardants, and heavy metals. This certification provides some assurance about the environmental impact of the materials, though it’s worth noting that this is becoming an industry standard rather than a distinguishing feature.

Manufacturing

Manufacturing location plays a crucial role in the environmental equation. The AS5 is made in the United States, which means two important things for its environmental impact.

First, American factories operate under stricter environmental regulations than many overseas facilities, ensuring better pollution control and waste management.

Second, domestic manufacturing significantly reduces transportation distances compared to mattresses made overseas, where a single container ship can produce as much pollution as millions of cars.

Amerisleep employs what they call a “zero-air emissions” manufacturing process. During my testing, this translated into practically no off-gassing smell when unboxing the mattress. This is a stark contrast to traditional memory foam mattresses that often require days of ventilation.

Shipping

Transportation efficiency deserves special mention. Amerisleep’s compression technology allows them to fit three mattresses in the space traditionally required for one uncompressed mattress, reducing shipping-related fuel consumption by up to 80%.

However, we should note that this compressed shipping method has become increasingly common in the industry, so while it’s environmentally beneficial, it’s not unique to Amerisleep.

Durability and Disposal

The mattress’s durability factors into its environmental impact in an important way. Throughout my testing and research of long-term user reviews, I found evidence suggesting the AS5 maintains its performance characteristics longer than many competitors.

A more durable mattress means less frequent replacement and, consequently, less environmental impact over time. It’s like buying one quality pair of shoes that lasts for years versus repeatedly replacing cheaper ones that wear out quickly.

However, the AS5 faces the same end-of-life challenges as other memory foam mattresses. The synthetic foams, even those with plant-based components, aren’t biodegradable.

Unless you have access to specialized mattress recycling facilities, the AS5 will likely end up in a landfill where it will persist for hundreds of years. This remains perhaps the biggest environmental challenge for the mattress industry as a whole.

Considering All the Factors

For those considering the AS5 from an environmental perspective, it represents a decently balanced choice. While not perfect (no memory foam mattress truly is) it incorporates several meaningful environmental considerations into its design and manufacture.

The combination of plant-based materials, efficient shipping, clean manufacturing, and long-term durability makes it a more environmentally conscious choice than many traditional mattresses, even if there’s still room for improvement in areas like end-of-life recyclability.

Given these factors, I’d say the AS5 represents a step in the right direction for environmental responsibility in the mattress industry, though we should continue to encourage manufacturers to push for even more sustainable solutions in future iterations.

And if you truly desire a soft mattress that is made with natural materials, I would readily recommend the Organica Plush.

Potential Drawbacks

Every mattress has its pitfalls, and the AS5 is no exception. While impressive, it’s not perfect, and I looked at both my experience and others’ reviews to see where its weaknesses lie.

From my experience and analysis of customer feedback, I believe these drawbacks are most significant for stomach sleepers, those seeking an extremely plush feel, budget-conscious shoppers, and individuals with mobility concerns.

However, for side sleepers and those who prefer a balanced feel between soft comfort and support, many of these limitations might be minor concerns compared to the mattress’s benefits.

Firmness Level Mismatches

Perhaps the most significant and somewhat counterintuitive drawback is that despite being marketed as an ultra-soft mattress, some users found it firmer than expected. In fact, 43 reviewers reported the mattress being “too hard.” This is more than the 9 who found it “too soft.”

This suggests there might be a disconnect between customer expectations of what constitutes an ultra-soft mattress and the actual feel of the AS5.

This is particularly relevant for those seeking an extremely plush sleeping surface, as they might find the supportive elements of the mattress create a firmer feel than anticipated.

Sleeping Position Limitations

The mattress shows clear limitations for certain sleeping positions. While it excels for side sleeping, back and stomach sleepers often report discomfort.

The soft nature of the mattress can allow hips to sink too deeply when sleeping on the back or stomach, potentially causing spinal misalignment.

This makes the AS5 a less versatile option for combination sleepers who frequently change positions or couples with different sleeping preferences.

Height and Sheet Compatibility

At 14 inches tall, the AS5’s thickness can present practical challenges. Several reviewers mentioned difficulty finding sheets that fit properly, as standard sheets often aren’t deep enough to accommodate the mattress height.

This height can also make the bed challenging to get into and out of, especially for shorter individuals or those with mobility issues.

As one reviewer, NotABarbie from Oak Park, CA, noted, “I have to half jump up and then make sure I’m not sitting right on the edge.”

Price Point Considerations

The AS5 represents a significant investment, positioned at the higher end of the memory foam mattress market. While many customers feel the quality justifies the cost, the premium pricing might be prohibitive for budget-conscious shoppers.

The review data shows fewer self-identified “budget shoppers” among purchasers, suggesting the price point may be a barrier for some consumers.

Initial Adjustment Period

Several reviewers mentioned needing time to adjust to the mattress’s unique feel. This adjustment period can last anywhere from a few days to a few weeks, during which some users reported temporary discomfort or soreness.

While this is common with many new mattresses, it’s important to note that the AS5’s distinctive feel might require more adaptation time than expected.

Edge Support Concerns

While not universally reported, some users mentioned limitations in edge support. This can be particularly noticeable when sitting on the bed’s edge or sleeping near the perimeter.

For those who frequently sit on the edge of their bed or couples who use the full surface of the mattress, this might be a consideration.

Temperature Regulation Variability

Although only two reviewers specifically mentioned heat retention issues, memory foam mattresses generally tend to sleep warmer than other types.

While the AS5’s cooling technologies appear effective for most users, very heat-sensitive sleepers might want to consider this characteristic carefully.

Mattress Policies and Prices

Think of these policies as your safety net. The sleep trial acts as your insurance policy against making the wrong choice, while the warranty protects your investment for years to come.

And understanding the pricing helps you evaluate whether the features and benefits justify the cost, especially when compared to other options in the market. These factors combine to form what I call the “complete value proposition” of the mattress.

I’ll break down each of these components in detail, explaining not just what they are, but why they matter and how they compare to industry standards.

Whether you’re considering the AS5 or just learning about mattress shopping in general, understanding these aspects will help you make a more confident and informed decision about your sleep investment.

Mattress Warranty

A warranty is important for several key reasons. First, a mattress is a significant investment that you’ll use every night for many years. Having a warranty protects this investment by ensuring you won’t have to pay the full cost of replacement if something goes wrong that isn’t your fault.

It also shows that the company stands behind their product and believes it will last. Amerisleep’s 20-year warranty suggests they trust their mattresses to remain durable for a long time.

For the first 10 years, if there’s a manufacturer’s defect or if your mattress gets a lasting dip deeper than 1.5 inches where you sleep (not counting the edges), Amerisleep will replace it with a new one. You won’t pay for the replacement mattress itself, but you might need to pay for shipping it to your home.

In the second 10 years, Amerisleep still helps if your mattress has problems, but you’ll need to pay half of your original mattress price for the replacement. You’ll also need to handle the shipping costs during this time.

Your warranty stays active only if you follow certain rules. You must keep the law tag on the mattress, avoid getting any stains on it, and use the right kind of base underneath.

The mattress can go on:

• A platform bed
• An adjustable base
• A solid foundation

If you prefer a box spring (which I wouldn’t recommend using but you can if you really want to), you need to put a solid piece of moisture-resistant plywood (at least 3/4 inch thick) on top of it.

If something goes wrong and you need to use your warranty, you’ll have to show your original purchase receipt. Amerisleep might also ask you to send pictures of your mattress and whatever you’re using to support it.

Here’s something important to remember: this warranty only applies to the first person who buys the mattress. If you give your mattress to someone else or sell it, the warranty doesn’t go with it. The new owner gets the mattress without any warranty coverage.

Mattress Sleep Trial

Having a sleep trial is crucial when buying a mattress, especially one you’re ordering online. While you can read reviews and research specifications, the only way to truly know if a mattress works for you is to sleep on it for an extended period.

Your body needs time to adjust to a new sleep surface, and you need time to evaluate how the mattress affects your sleep quality and comfort.

Your 100-night trial period doesn’t start until the mattress arrives at your home. If you’ve also purchased an adjustable bed base with your AS5, the trial won’t begin until both pieces arrive. This ensures you get a full 100 nights with your complete sleep setup.

While some people fall in love with their AS5 immediately, Amerisleep notes that it can take up to 30 nights for your body to properly adjust to a new mattress. If you notice minor aches or stiffness during this initial period, it’s usually just your body adapting to the new support system.

And if you decide the AS5 isn’t the right fit for you, you can return it for a full refund.

However, there’s one key requirement: you must sleep on the mattress for at least 30 nights before starting a return. This minimum trial period ensures you’ve given your body enough time to adapt to the mattress.

To initiate a return within the 100-night window, simply contact Amerisleep. They make the process straightforward:

• Their support team in Arizona will help you
• They’ll coordinate a free pickup of the mattress
• Once the return is processed, they’ll issue your refund

This risk-free trial means you can try the AS5 thoroughly in your own bedroom, with your own pillows and sleeping habits, without worrying about making the wrong choice.

It takes the pressure off making an immediate decision and ensures you only keep the mattress if it genuinely provides the comfort and support you need.

Mattress Sizes and Prices

The Amerisleep AS5 memory foam mattress is available in all standard mattress sizes, with the thick 14-inch profile being consistent across all sizes.

In terms of market positioning, the AS5 is positioned as a premium mattress with pricing that reflects its high-end materials and construction. It’s priced higher than many popular bed-in-a-box brands like Casper or Nectar, which typically range from $1,000 to $1,500 for a queen size.

However, when compared to other luxury mattress brands, the AS5 is actually competitively priced. It’s generally less expensive than comparable models from brands like Tempur-Pedic or Aireloom, which often exceed $3,000 for a queen size.

While the AS5 represents a significant investment compared to budget mattresses, its pricing is justified by its premium materials and construction. In other words, the price makes sense given the AS5’s features:

• Premium plant-based Bio-Pur® memory foam
• Advanced cooling technology
• 14-inch profile (thicker than many competitors)
• Strong emphasis on durability with a 20-year warranty
• Made in the USA with eco-friendly manufacturing processes

For those seeking a luxury ultra-soft memory foam mattress, it offers good value relative to other high-end brands. Yes, even though it’s more expensive than some mainstream direct-to-consumer options.

Customer Reviews

The AS5 has garnered overwhelmingly positive feedback, earning a remarkable 4.8 out of 5 stars based on over 500 customer reviews. Perhaps most tellingly, 96% of reviewers would recommend the mattress to others, indicating exceptional customer satisfaction.

Looking at frequently mentioned positives, comfort emerged as the leading benefit with 447 mentions. This was closely followed by good support (425 mentions) and soft feel (388 mentions).

Many customers specifically praised the mattress’s ability to hold its shape over time (369 mentions), while 170 reviewers highlighted its sturdy construction.

Specific Positives

The AS5 appears to particularly excel for side sleepers. Multiple reviewers described significant improvements in shoulder and hip pain after switching to the AS5.

For example, one reviewer named Lefty from Virginia, who has deformed hips and shoulder joints, called it “the best decision in my life,” noting the perfect balance of softness and support for side sleeping.

A recurring theme in the feedback was pain relief. Many customers reported reduction or elimination of various types of pain, particularly in the shoulders, hips, and back.

Victoria from Tampa, FL specifically mentioned how the mattress effectively relieved pressure points and significantly reduced her discomfort.

Multiple reviewers also highlighted the mattress’s excellent motion isolation properties. As one reviewer, KM from Michigan, noted, “I do not feel my partner get in and out of bed.” This feature seems particularly valuable for couples with different sleep schedules.

Despite being a memory foam mattress, which traditionally can trap heat, very few customers reported issues with temperature. In fact, only 2 out of over 500 reviewers mentioned the mattress sleeping hot, suggesting the cooling technologies are working effectively.

Long-term users provided positive feedback about the mattress’s durability. For instance, Andrea from PA reported that after almost 5 years of use by two adults and two dogs, the mattress was “still fantastic” with no sagging or loss of shape.

Areas of Concern

While negative feedback was limited, there were some consistent themes:

• 43 reviewers found the mattress too hard, despite it being marketed as ultra-soft
• 9 users reported the development of cavities or impressions over time
• Some customers mentioned the 14-inch height making it challenging to find properly fitting sheets
• A few reviewers noted that the edge support could be improved, particularly for sitting

Several reviewers mentioned a brief adjustment period when first using the mattress. As Meg from Asheville noted, it took about a week to break in the mattress and get used to its feel, after which she experienced significantly improved sleep quality.

While some reviewers mentioned the higher price point, many felt the quality justified the cost. Multiple customers became repeat buyers, with several mentioning purchasing additional AS5 mattresses for other rooms or homes, suggesting strong satisfaction with the value provided.

Mattress Care and Maintenance

In my experience, I’ve found that many people underestimate the impact that regular maintenance can have on a mattress’s performance. The AS5, with its sophisticated layering system and premium materials, particularly benefits from proper care.

See, while the Bio-Pur® foam and Active Flex layers are designed to maintain their properties over time, like any high-quality materials, they perform best with proper attention and care.

Understanding how to protect and maintain your AS5 isn’t just about preserving its physical condition. It’s about ensuring that the mattress continues to deliver the same level of comfort, support, and temperature regulation that impressed you on day one.

Protection from Day One

The most important step happens before you even start using your mattress—installing a high-quality waterproof mattress protector.

It’s like putting a phone case on a new smartphone, because it’s much easier to prevent damage than to fix it later. The mattress protector serves as a barrier against spills, sweat, dust mites, and other potential contaminants that could compromise your mattress’s integrity.

Regular Cleaning Protocol

Even with a mattress protector, your AS5 benefits from regular maintenance cleaning.

Every three months, remove all bedding and use your vacuum’s upholstery attachment to clean the mattress surface. This removes dust, dead skin cells, and other particles that can accumulate over time.

When vacuuming, use gentle, overlapping strokes and pay special attention to seams and crevices where debris tends to collect.

Your AS5 also benefits from regular “breathing” time. When changing sheets (ideally weekly), leave the mattress bare for a few hours. This practice allows any accumulated moisture to evaporate and helps maintain the mattress’s freshness.

During this time, open windows if weather permits to promote air circulation.

Handling Spills and Stains

If you encounter a spill or stain, immediate action is crucial. Here’s the proper procedure to clean a mattress:

• First, blot the area with a clean, dry white cloth to absorb as much liquid as possible. Avoid rubbing, as this can push the stain deeper into the mattress materials.
• Then, create a cleaning solution using mild detergent and cold water. Emphasis on cold, as warm water can set certain stains.
• Apply this solution sparingly using a clean white cloth, being careful not to oversaturate the foam. Remember, excess moisture in foam can lead to mold or mildew development.

After cleaning, use a fan to ensure the area dries completely. This might take several hours, but it’s essential to prevent any moisture-related issues.

Allow the mattress to dry fully before replacing bedding.

Foundation Maintenance

The foundation supporting your AS5 is crucial for its longevity. Regularly inspect your bed frame or foundation for any signs of wear, loose screws, or broken slats.

If using a slatted base, ensure the slats are no more than 2.75 inches apart, as specified in the warranty requirements. Any issues with the foundation should be addressed promptly to prevent mattress damage.

Dealing with Odors

If you notice any odors developing, sprinkle baking soda over the mattress surface and let it sit for several hours (ideally 24 hours if possible). The baking soda will absorb odors and moisture.

Afterward, vacuum thoroughly using the upholstery attachment. This natural deodorizing method is particularly effective after humid summers or if someone has been ill.

Support and Rotation

While Amerisleep states that rotation isn’t necessary for the AS5, some users prefer to rotate their mattress every 3-6 months. If you choose to rotate, remember that this mattress is quite heavy. Always get help to avoid injury or damage to the mattress.

Never flip the mattress, as it’s designed with a specific top-to-bottom layering system.

Temperature and Environment

Keep your bedroom environment moderate. Excessive heat or humidity can affect the foam materials over time. Aim for a room temperature between 65-75°F (18-24°C) with relative humidity between 30-50%.

If you live in a particularly humid climate, consider using a dehumidifier to protect your mattress.

Annual Deep Assessment

Once a year, perform a thorough inspection of your mattress. Check for any signs of sagging, particularly in the areas where you typically sleep. Look for any visible damage to the cover or seams.

This annual check helps you catch and address any issues before they become serious problems that might void your warranty.

Closing Thoughts

After spending countless hours testing every aspect of the AS5 (from bouncing on its edges to taking marathon weekend naps) I can confidently say this mattress brings something special to the bedroom.

Like a perfectly toasted marshmallow, it manages to be soft and luxurious while still maintaining its structure where it counts.

With its innovative Bio-Pur® foam providing that “just right” balance of plush comfort and support, exceptional motion isolation that could keep a coffee cup steady during an earthquake, and cooling technology that actually works (unlike your ex’s promises), the AS5 earns a solid 9 out of 10.

Sure, it’s not perfect. Stomach sleepers might want to look elsewhere, and your wallet will definitely feel lighter. But for side sleepers seeking cloud-like comfort without sacrificing support, this mattress delivers.

Think of it as the difference between flying economy and first class. Yes, both will get you there, but one definitely makes the journey more enjoyable. While the price tag might make your credit card wince, the AS5’s durability and 20-year warranty mean you’re investing in thousands of nights of better sleep.

Is it worth the investment? For side sleepers and those who prioritize pressure relief without feeling stuck in quicksand, absolutely.

Just remember to measure your doorways first! At 14 inches thick, this mattress is like trying to maneuver a wedding cake through a cat flap.
