The Facts about Fiberglass in Mattresses

Unfortunately, there are lots of mattresses on the market nowadays that contain fiberglass. There are no real benefits to having fiberglass inside a mattress, so you might be wondering why any mattress would contain this potentially hazardous industrial material.

The reality is fiberglass is only in any mattress because it is cheap. This typically means it is more commonly found in mattresses that are marketed as affordable. That means you need to be especially careful with inexpensive mattresses, paying attention to their ingredients to ensure you are not purchasing a mattress that contains glass fiber.

“As someone that prioritizes the well-being and comfort of my patients, I hold quality standards in high regard. When it comes to mattresses, I highly recommend choosing ones that are free from fiberglass. Fiberglass, although commonly used as a fire retardant, can pose potential health risks and irritate the respiratory system,” says Dr. Jordan Burns.

“By opting for mattresses without fiberglass, you prioritize your health and ensure a safer sleep environment. Investing in quality mattresses that adhere to strict safety standards not only promotes better sleep but also supports your overall musculoskeletal health and well-being. Your comfort and safety are my top priorities, and I recommend mattresses without fiberglass to help you achieve a truly restorative and health-conscious sleep experience.”

What Fiberglass Is

Fiberglass is an industrial type of reinforced plastic that gets its strength from tiny shards of glass inside it. These glass particles increase the strength of the plastic without eliminating its flexibility. This makes fiberglass one of the most ubiquitous materials in the industrial world.

You will find fiberglass in just about anything. It’s in your car’s brake pads and under its hood. It’s in your home’s insulation and bathtub or shower. It might even be in your favorite sporting equipment, such as surfboards, boats, hockey sticks, and more.

Typically, you are safe from fiberglass exposure either because you will never come into contact with the fiberglass or because it is a type of fiberglass that has a rigid structure that cannot release glass particles. This is not the case for the fiberglass inside your mattress. Not only are you exposed to it every night, but it is a type that can easily release microscopic glass shards.

The type of fiberglass that goes inside mattresses is called glass cloth. With glass cloth, threads of fiberglass are woven into a sheet. This sheet is then made into a sock that covers the internal components of the mattress, sitting right under its cover and right next to your skin.

Why Mattresses Sometimes Contain Fiberglass

There’s only one reason mattresses would ever contain fiberglass: fire protection. It may surprise you to learn that the components inside your mattress are highly flammable, especially synthetic foam. To protect consumers from fire, all mattresses have to pass certain fire safety standards.

Mattresses are usually made fireproof by wrapping internal components in some sort of inflammable material to prevent the foam from bursting into flame. There are many different materials that can be used as a fireproof sock.

Fiberglass is the cheapest way to make a mattress sufficiently fire retardant. If exposed to high heat, fiberglass will melt rather than bursting into flame. When it melts, it forms a barrier over the flammable foam to keep it from igniting. There are plenty of other materials that can do this, but none are as inexpensive as fiberglass.

Dangers of Fiberglass

Fiberglass might be flame-retardant, but it is also quite dangerous. When you have fiberglass inside your mattress, there is the constant threat of fiberglass exposure – no matter what the mattress manufacturers say to the contrary.

When you’re exposed to fiberglass, it can cause all kinds of health issues ranging from eye irritation and vision problems to skin rashes and even chronic lung infections. This is because the tiny shards of glass inside fiberglass work their way out of this industrial material to fill the air and coat surfaces.

When you breathe in fiberglass or come into contact with it externally, it leaves tiny cuts all over every part of your body that it touches. This is why you can experience so many issues when exposed to fiberglass. It is literally injuring you.

Fiberglass Alternatives for Mattresses

Thankfully, you don’t have to have an industrial material inside your mattress. There are lots of alternatives that are much better at comfortably and safely protecting you from fire. Another affordable, synthetic fire barrier is silica fiber.

Silica is just as flame retardant as fiberglass, but it is much less of a threat to your health. Silica melts just like fiberglass does when it comes into contact with high heat. Unlike fiberglass, silica fibers cannot release microscopic glass shards into the air, which means they will not cause the same irritation.

There are lots of natural fibers that can also provide fire protection. Vegan mattresses often use some type of cellulose-based rayon, such as thistle or viscose. Other vegan mattresses may use mineral infusions to make their foam itself resistant to fire.

Wool is also another common natural fireproofing material. Wool is difficult to ignite and can often extinguish flame on its own. Furthermore, wool is also highly breathable and pressure-relieving. This means it doesn’t just protect you from fire, but it also adds another layer of comfort to your sleep surface.

How to Tell if a Mattress Has Fiberglass

All mattresses are legally required to come with a list of ingredients used inside them. This means that if you’re buying a brand-new mattress, it should be easy to tell if it has fiberglass as looking at this ingredients list.

If you want to know whether your existing mattress has fiberglass inside it, this may be a little harder. You could search for it online based on its brand and model number. If you can’t find it on the internet, look at the tag on the cover.

This tag often comes with instructions for how to care for the mattress. If this tag forbids you from removing the cover, that is a big clue that there is fiberglass underneath.

How to Choose the Best Mattress without Fiberglass

Being free of fiberglass is just one of several qualities your mattress needs to have in order to give you a quality night’s sleep. You’ll also need to think about your mattress’s material and its firmness for a truly perfect sleep experience.

Ideal Materials for Mattresses without Fiberglass

Your mattress’s material decides a lot about how the mattress feels. It decides everything from how buoyant it is to how cooling to how responsive and even how contouring.

This means you need to understand a little bit about your sleep needs before choosing your ideal type of mattress. Each different mattress material has different strengths and weaknesses that may or may not cater to you.

Memory Foam

Memory foam is one of the most popular mattress materials on the market for a lot of reasons. It is the absolute most contouring mattress material out there. A memory foam mattress is also highly affordable and decently durable. This makes for a comfortable bed that won’t break the bank or require you to replace it after only a few years.

Memory foam is also the material that offers the most pressure relief, thanks to its contouring nature. When you sleep on a memory foam mattress, it will mold itself to your body in a way that no other material can. This means memory foam is perfect for those who need pressure relief.

Memory foam’s affordability is also one of the things that attracts many people to this synthetic foam. Memory foam is more durable than the cheapest type of mattress (innerspring) and almost as inexpensive. This makes it the most affordable mattress material over time.

The main issues with a memory foam mattress are its slow response time and its tendency to retain heat. Memory foam mattresses tend to bounce back slowly in comparison to other materials. This may be a problem for you if you like to toss and turn in your sleep. Memory foam beds also tend to retain more body heat, which can be a problem for those who sleep hot.

Latex Foam

Natural latex foam comes from the sap of the rubber tree and is a fantastic alternative to memory foam for those who want responsiveness and breathability. Latex is naturally springy and breathable. This means it’s much more cooling and bouncy than memory foam.

Natural latex is also highly buoyant, meaning it’s a fantastic option for sleepers who like a more supportive feel. And it’s more durable than any other mattress material on the market. You can expect pure latex mattresses to last for decades.

Natural latex also is much more eco-friendly than memory foam. This is not only because latex manufacturing produces much less toxic waste than memory foam manufacturing, but also because natural latex is biodegradable and recyclable. Meanwhile, memory foam will sit in a landfill for just shy of forever.

The main problem with natural latex is its expense. Though it is the most durable mattress type, natural latex is also the most expensive type of mattress upfront. This can be prohibitive for many people who cannot plug down thousands of dollars for a mattress. Latex also has the potential to trigger symptoms in those allergic to it.

Hybrid

When it comes to comfort, it’s quite possible nothing beats a hybrid mattress. Hybrid mattresses combine a support layer of pocketed coils with a comfort layer of either latex or memory foam. There may also be foam transition layers in between. This means you get all the benefits of coils and all the benefits of foam all at the same time.

Hybrid mattresses feature coils that are individually wrapped in their own foam or fabric cases. This means the coils can all move independently of one another. This gives them the ability to adapt to your shape even better than base foam can. And they’re more responsive than base foam to boot – without all the motion transfer that comes with traditional open coils.

Pocketed coils are also more breathable than base foam, which means they keep more air flowing through the bottom of your mattress. This can make them another fantastic option for hot sleepers and active sleepers who need responsiveness.

The one issue with pocketed coils is the fact that they break down faster than base foam because they lose their tension. This means your hybrid mattress will not last as long as most pure foam mattresses. Combine that with their higher average initial price tag, and you have the most expensive mattress type over the course of its lifetime.

Innerspring

Innerspring mattresses are typically best avoided. They are created using older sleep technology that has a lot of problems that newer sleep technologies do not have, and that can include difficulty finding fiberglass-free mattress with traditional spring support. Comfort-wise, most of the innerspring mattress’s issues stem from its open coil support layer, in our experience.

Open coils do not have a fabric or foam casing and are wired together using steel cables. This means that the entire support core moves as one unit. Open coils do not contour very well because of this design flaw. They tend to sag under your heavier parts and exert pressure on areas they should compress underneath.

Furthermore, open coil support cores also amplify motion and transfer it all over the bed, making them a poor choice for couples. And the metal-to-metal contact from the unencased coils means most innerspring mattresses start making squeaking and creaking noises within a couple of years.

Open coils also lose tension and break down even faster than pocketed coils. You can expect to replace your innerspring mattress in less than 10 years. For all these reasons, we recommend hybrid mattresses for those who want a mattress with coils.

Ideal Firmness for Mattresses without Fiberglass

Your fiberglass-free mattress also has to have the right firmness in order to give you the best comfort. Firmness is measured on a scale of one to 10, with 10 being the firmest.

Most of the time, you will not find mattresses that are firmer than about an eight or softer than about a three because all mattresses need at least some support or some compression, regardless of the ratio.

We compared some of the more common firmnesses in-depth in a few of our buying guides:

• Firm vs. Soft Mattresses
• Firm vs. Medium Mattresses
• Plush vs. Medium Mattresses

Your sleep position and body weight can both impact your firmness needs, though your sleep position is the thing that decides your firmness baseline.

Sleep Position

Your sleep position dictates your baseline firmness level because it decides how your body contacts the bed, where your pressure points are, and how much spinal support you need. This means you should decide your firmness based on how you sleep, and go up or down from there based on your body weight.

Back Sleepers

Back sleepers need a mix of support and pressure relief that slightly favors support. This is because back sleepers can have problems with both sinkage and a lack of contouring if they don’t get the right firmness mix.

When you sleep on your back, your body can sink into the bed if it is too soft. This will leave you sleeping in a hunched position and can cause back and neck pain. Conversely, if your mattress is too firm, it can allow your lumbar region to collapse onto the bed and leave you with lower back pain.

To get the right amount of support and contouring, back sleepers should generally choose medium-firm mattresses (6 of 10). These mattresses for back sleeping offer the perfect balance of lift and compression to follow the curve of your spine without letting you sink.

Combo Sleepers

Combination sleepers do not have a strong preference for any specific sleeping position. Rather, they may adopt any sleep position on any given night. This means they need a highly versatile mattress that can accommodate any sleep position without being designed for only one.

Typically, medium mattresses (5 of 10) fit this bill the best. Medium mattresses offer an even balance of pressure relief and support. This means they are firm enough for you to sleep on your stomach and back some of the time and soft enough for you to sleep on your side some of the time. This is perfect for most combination sleepers.

Side Sleepers

Side sleepers typically need softer mattresses. When you sleep on your side, your body weight pushes one of your shoulder and hip joints into the bed. If your mattress resists this pressure instead of absorbing it, this can leave you with pain in these sensitive pressure points. This means you need a mattress that can compress deeply to cushion your hips and shoulders.

Medium-soft mattresses (4 of 10) are typically best for side sleepers because they offer lots of pressure relief without sacrificing too much support. These mattresses for side sleeping help ensure the spine remains aligned and the joints are protected at the same time.

Stomach Sleepers

Stomach sleepers typically need the firmest mattresses. This is because sleeping on your stomach allows your pelvis to sink into the bed. When this happens, it overarches your spine and can leave you with pain in your lumbar region.

Firm mattresses (7 of 10) counter sinkage and ensure your pelvis stays lifted to keep your spine aligned. For added spinal alignment, consider sleeping with a flat pillow or no pillow so that you do not have to twist your neck as much while you sleep.

Body Type

Your body type does not have as profound an impact on your firmness needs as your sleep position, but it can sometimes influence your firmness needs.

If you fall into what the mattress industry has labeled the average human weight range (130 to 230 pounds), then you don’t have to do anything with your firmness at all. You can just pick the mattress firmness level that corresponds to the way you like to sleep. If you fall outside of this range, you may have to take that into account.

Petite Sleepers

Those who weigh less than 130 pounds are considered petite sleepers. If you fall into this weight category, you usually need to go down a firmness level from the one that matches your sleep position.

This is because people who weigh less than 130 pounds tend to not get enough compression out of their mattresses for adequate pressure relief. Going one firmness level down can counter this issue.

For instance, a petite combination sleeper would go down from a medium to a medium-soft mattress to get the same amount of compression as an average-weight sleeper would get from a medium mattress.

Plus-Size Sleepers

Those who weigh more than 230 pounds are considered heavier or plus-size sleepers. When you are a heavier sleeper, you tend to have the opposite problem of a petite sleeper. You get too much compression out of a mattress that matches your sleep position.

Too much compression can lead to sinkage and spinal misalignment, so it’s important to ensure you get enough support by going up a firmness level from the one you would choose for your sleep position.

For instance, a heavier back sleeper would likely need to upgrade from a medium-firm to a firm mattress to get sufficient support for both their sleep position and their body weight.

Saving on a Mattress without Fiberglass

When it comes to the best time to buy a mattress, it’s always when you see your current mattress is unfit for sleeping on. However, many prefer to wait until one of the year’s big mattress sales.

You can also save by shopping online. Online web stores tend to have more competitive prices due to fewer overhead costs, and with a lengthy sleep trial, you won’t miss the benefit of trying a mattress out at a showroom or furniture.

Bottom Line

If you want to find a fiberglass-free mattress, it’s easy. All you have to do is make sure you are reading the mattress’s ingredients list and picking one that fits your material and firmness needs according to your sleep style and preferences.
