11 Best Mattresses Without Fiberglass: A Buyers’ Guide

Fiberglass, hard plastic with glass pieces, is common in mattresses. It acts as a flame barrier, giving you extra protection and leeway time in case of emergencies. But beyond safety reasons? Our expereince and research shows that fiberglass isn’t the best. It can be irritating to your skin and can aggravate allergies and asthma in some cases.

Although fiberglass is commonly found in mattresses, they’re not the only fire barrier out there. Lots of mattress manufacturers use more natural fire retardants in their beds to keep your sleep environment cleaner and safer for you. Today, we take a look at the best mattresses without fiberglass and chat more about fiberglass and its alternatives.

Our findings suggest that memory foam mattresses are notorious for containing fiberglass, but not the Amerisleep AS3. Unlike most memory foam mattresses we have encountered in our research, the AS3 is made from plant-based memory foam.

“Studies have shown that foam mattresses can help reduce the development of pressure injuries when compared to standard mattresses,” says Dr. Miho Tanaka.

The AS3 is made in the USA and CertiPUR-US® certified to ensure your bed is free of harmful chemicals and heavy metals. It comes with free shipping, free returns, a 100-night sleep trial, and a 20-year limited warranty.

How Lying Down Feels

During our investigations, we found the Amerisleep AS3 has a medium firmness suited for side and combo sleepers. Our research team concluded that the Amerisleep AS3 is neither too soft nor too firm. We also found that the foam layers isolate motion. So if you share a bed, you won’t disrupt your partner in the middle of the night. And if you do get out of bed, the foam snaps back into shape and won’t feel saggy.

For couples with different firmness needs, this medium mattress provides balanced support and makes for a great compromise, per our expertise. Don’t just take our team’s word for it, though, as we also dedicated hours of research to seeing what other people think about the Amerisleep AS3.

According to several influencers, the AS3 is not only eco-friendly and fiberglass-free, but it also offers exceptional comfort and support. Anna Gandrabur, a popular Instagram influencer, mentioned that she experienced even better sleep quality on this mattress due to its eco-friendly and fiberglass-free features.

Claire Berard, another influencer, raved about the AS3’s cooling and comfortable properties, which alleviated her back pain as a side sleeper. Lastly, Meredith Drew, an influencer in the design industry, commented on the AS3’s soft and responsive feel, which her daughter described as sleeping on a cloud.

And what did the average consumer tester have to say?

Morgan highly recommended the Amerisleep AS3. She found it to be durable and long-lasting, with no cavity or dipping. She appreciated that it was made in the USA, non-toxic with no fiberglass, and had excellent reviews. She also purchased the Amerisleep foundation and received a replacement when the joint started separating. Morgan rated the mattress 5 out of 5 and did not have any negative comments.

Pat also had a positive experience with the mattress but found it to be slightly too soft. Despite this, they would still recommend the mattress and gave it a rating of 4 out of 5. Their primary concern was a fiberglass-free mattress, and the AS3 satisfied them in that regard.

Inside the Mattress

Amerisleep makes the AS3 mattress with three layers of foam. The AS3’s cover is made from a fabric that promotes air circulation and draws away heat and moisture from your body. Known as Refresh, this fabric cover also features thermo-reactive minerals that convert body heat into infrared energy for greater restoration as you sleep.

Under the cover is Bio-Pur® memory foam. Amerisleep makes it with castor oil instead of petroleum, resulting in a long-lasting and breathable memory foam. At the same time, Bio-Pur® is just as pressure-relieving as normal memory foam!

The second layer of the AS3 is Affinity foam. This layer features HIVE®, a zoned technology divided into five zones. The layer features cutouts to provide extra support under the head, back, and legs, and extra cushioning under the hips and shoulders.

At the base of the AS3 is Bio-Core® foam. It’s firm and durable to support healthy spinal alignment. Plus, the layer is critical in helping your mattress last without sagging.

Hot sleeping is all too common, but not with the Zoma Hybrid. Drawing from our experience, we have found that the Zoma Hybrid is built to dissipate body heat and moisture, while still providing exceptional comfort and support.

“Studies have shown thatVerified Source National Library of Medicine (NIH)World’s largest medical library, making biomedical data and information more accessible.View source sleep quality can be affected by skin temperature, and the thermal properties of bedding that can influence cooling have been shown to play an important role in this,” notes Dr. Miho Tanaka.

When we trialed this product, we discovered that its 12-inch thickness and medium feel make it suitable for most sleeping positions. We recommend it especially athletes, people dealing with chronic pain, and of course, hot sleepers.

The Zoma Hybrid is made in the USA and CertiPUR-US® certified foams. Every Zoma Hybrid includes free shipping and returns, a 100-night risk-free trial, and a 10-year warranty. 

How Lying Down Feels

When lying down on the Zoma Hybrid, we found ourselves sleeping deeper thanks to its restorative qualities. Our findings indicate that the mattress also enhances muscle recovery and boosts physical performance in the mornings.

The cooling foam and moisture-wicking cover on the Zoma Hybrid ensure you never wake up feeling hot or sweaty. We determined through our tests that it conforms to your curves, decreasing pressure on your lower back, hips, and shoulders. At the same time, it provides enough spinal support to lift your body and prevent you from feeling “trapped.”

Inside the Mattress

The Zoma Hybrid is made up of two foam layers with pocketed coils on a final base foam layer. Wrapped over the foam layers is an AirCloth cover. Our investigation demonstrated that this mesh fabric is stretchy and absorbs moisture and heat, so you sleep cool.

The Zoma Hybrid’s comfort layer is made from cooling gel foam, staying cool while relieving pressure. Next is a layer of Reactiv™ transition foam, which we observed performs similarly to latex. It’s bouncy and lifts your body, ensuring you don’t sink into your mattress and throw your spine out of alignment.

The Zoma Hybrid’s pocketed coils base is built to protect your spine and resist sagging. The final foam layer structures the coils, giving them a firm surface to retract into and bounce off from. Our findings suggest that this way, you can enjoy your Zoma Hybrid for years to come.

Based on our firsthand experience, we can confirm that hybrid mattresses can provide more effective contouring and conforming cushion than a traditional innerspring mattress. This is thanks to their thick foam tops and pocketed coil interiors. Even among a mattress type known for its comfort, the Vaya Hybrid stands out for blending high-quality materials with affordable prices.

Every Vaya Hybrid mattress ships free and includes a 100-night sleep trial and a 10-year warranty with your purchase.

How Lying Down Feels

When we trialed the Vaya Hybrid, we found it to offer a plush and soft feel, molding to the body and providing pressure relief and support where needed. Our investigation demonstrated that the underlying layers also supported the spine and prevented sinking or discomfort.

We found in our tests that the comfort and support it provides at such an affordable price point is impressive. Some of our team did note the cover feels a little thin along the sides, but they didn’t find it all that noticeable when you stretch out on the mattress surface. Based on our experiences, one of the standout features of the Vaya Hybrid mattress is its ability to cater to both supportive and soft preferences.

Shoppers don’t have to just take our word for it, though. Many users report feeling cradled by the mattress, enjoying a cocoon-like sensation that relaxed them into a deeper, more restful sleep. More specifically, consumer reviewers Sharon, Horace, and Michelle are all extremely satisfied with their Vaya Hybrid mattresses.

Sharon loves her bed so much that she convinced her two daughters and granddaughter to purchase Vaya mattresses as well. She raves about the comfort of the mattress and the heavenly Vaya pillows. Horace also highly recommends the Vaya Hybrid, claiming that he hasn’t gone to work since it was delivered because all he wants to do is sleep on his “cloud.”

Michelle was delighted to find a bed that is completely fiberglass-free, and she has been sleeping better than ever since purchasing her Vaya Hybrid. She finds the mattress to be both comfortable and sturdy, and she appreciates that it is tall enough to require deep pocket sheets.

Jon, on the other hand, rates the Vaya Hybrid 4 out of 5. While he still finds the mattress to be very good, he notes that he was previously sleeping on an older twin mattress and therefore can’t fully compare it to other options.

Inside the Mattress

The Vaya Hybrid has four layers within a lightweight, breathable knit cover. The surface feels quite plush for a medium-feel mattress, thanks to the top layer of quilted cotton. Aside from establishing a cool, dry surface, the cotton also provides natural cushion for sensitive sleepers.

The second layer of the Vaya Hybrid provides the bed’s main comfort, with 2 inches of conforming and pressure-relieving foam. This comfort foam was designed by Vaya to swiftly release heat with its lightweight, breathable structure, while also serving as durable, responsive cushion.

The third layer of the Vaya Hybrid is pocketed coils, with every coil wrapped to provide near-perfect motion isolation. Couples sharing a mattress can freely move about in the night without disturbing the other’s rest.

“Reducing motion can be helpfulVerified Source National Library of Medicine (NIH)World’s largest medical library, making biomedical data and information more accessible.View source for sleep when sharing a bed, as this has been associated with worse objective measures of sleep,” says Dr. Tanaka.

The last layer of the Vaya Hybrid is stiff and durable base foam. This foam layer gives the coils a supportive surface and extends the mattress’s expected lifespan.

The latest model in the Zoma line-up is also their thickest and most luxurious model yet. Aside from the fiberglass-free design that Zoma mattresses rely upon, our team discovered through using this product that the Zoma Boost also relies on soft, graphite-infused foam for comfort and bouncy pocketed coils.

After putting it to the test, we can say that you won’t just feel safe on the Zoma Boost, but comfortably embraced and carried off to deep, relaxing sleep.

How Lying Down Feels

The Zoma Boost was engineered to deliver on two points—enduring coolness and soft, pressure-relieving cushion. When we trialed this product, we found that the quilted surface improved upon the classic pillow top feel, feeling light and airy instead of the slick finish that older pillow top models can have.

Inside the Mattress

Along with a fiberglass-free construction, the Zoma Boost features a soft and airy ultra-cool fabric cover, separate from the heavier and thicker fabrics found on many other mattresses. The fabric offers a pleasantly light and refreshingly cool sensation, feeling like a soothing cool compress on aching muscles or your very own personal cloud.

The Zoma Boost boasts two comfort layers of foam, delivering soft, cooling, and responsive comfort. The graphite infusion inside the Zoma Boost better draws excess heat away from the sleeper, minimizing sleep interruptions during the night.

The transition layer of Reactiv™ foam sits in the middle of the mattress. Reactiv™ is engineered to be buoyant and adaptable, eliminating any sinkage that can hamper a sleeper’s movements.

The bottom of this soft mattress is a series of individually wrapped coils, isolating motion. These coils rest on a base t to strengthen the mattress’s overall stability.

When spending thousands of dollars on a bed, it’s understandable that you’d want it to be free of potentially harmful chemicals. That’s why we love the Saatva Classic during our tests and search for a bouncy mattress free of fiberglass. This top-notch bed contains two types of steel coils, plush latex, organic cotton, and no fiberglass!

What does Saatva use instead of fiberglass? Our researched showed that their mattresses rely on a mix of wool and thistle for flame protection. You receive free shipping and returns, a 365-night guarantee, and a lifetime warranty with a purchase of the Saatva Classic.

How Lying Down Feels

The Saatva Classic comes in three firmnesses and two thicknesses. This way, anyone can enjoy the unique, high-end support of the mattress. This firmness range in our experience means that it’s great as a mattress for side sleepers, back sleepers, or stomach sleepers.

In our tests, we found the Saatva Classic mattress has a luxurious feel that provides excellent support and pressure relief. You can settle across the surface and gently sink in while still feeling supported.

Inside the Mattress

The Saatva Classic has a 3-inch Euro pillow top made from a blend of organic and hypoallergenic cotton, plush fibers, and foams. This cover fabric is also treated with a botanical compound that establishes an antimicrobial barrier, ensuring the Saatva Classic is not just fiberglass-free but also bereft of harmful and smelly microbes.

Beneath that are two types of steel coils—smaller micro-coils that soothe pressure points and larger coils built to prevent sagging. The Saatva Classic also features a patented and CertiPUR-US® certified back support system.

Most mattresses without fiberglass can be costly, often costing over $1000, but not the Zoma Start. The Zoma Start starts at only $375! Zoma designed this budget-friendly mattress to enhance your sleep, muscle pain, and physical performance. With the Zoma Start’s medium firmness, it’s a good choice for all types of sleepers, even couples!

Based on our observations when trying to avoid beds with fiberglass, we have found that many of them contain wool. While wool can be great and is commonly sustainably sourced, it’s okay to still want something entirely plant-based. That’s why we recommend the Avocado Vegan Mattress.

Avocado offers free shipping and returns, a 365-night trial, and a 25-year warranty with every purchase.

How Lying Down Feels

With the Avocado Vegan Mattress, you have the option between the standard or pillow top variations. The standard is 11 inches thick and has a medium-firm feel. The pillow top variation is 13 inches thick with a medium feel. Both mattresses contain the same materials, just at different thicknesses.

Inside the Mattress

The Avocado Vegan Mattress is the plant-based variation of Avocado’s best-seller, the Avocado Green Mattress. This vegan certified and PETA-approved mattress contains cotton in place of the wool found in the original mattress.

The mattress’s cover and batting are made from Global Organic Textile Standard (GOTS) certified cotton. The organic cotton cover combined with natural graphite powder act as the Avocado Vegan Mattress’s flame barrier.

What is Fiberglass?

Fiberglass is a plastic flame barrier reinforced with glass fibers. The material can be randomly arranged, woven, or compressed into a flat sheet.

In the United States, mattresses and mattress pads must contain a flame barrier or retardant to meet federal safety standards. On the off chance that there is a fire, a flame retardant prevents your mattress from rapidly going up in flames. This gives people time to escape safely and has saved lives in the process.

Mattress companies once used chemical fire barriers in their beds, but they were quickly banned due to their toxicity.Verified Source Environmental Protection Agency (EPA)Works to control/prevent natural and manmade disasters.View source The flame retardants in mattresses must be chemical-free to pass the United States’ current safety requirements.

Fiberglass is both cheap to produce and non-toxic, which is why it’s one of the most common fire barriers used today. In the event of a fire, the fiberglass would melt, sealing your mattress in the process and slowing the spread of flames.

Why Are Mattresses With Fiberglass Bad?

Fiberglass won’t cause any long-term side effects or conditions, but it’s still not the best for you. Sleeping on a mattress with fiberglass can cause skin, eye, throat, and nose irritation. Some may experience coughing, a sore throat or nose, red eyes, stomach pain or discomfort, and itchiness. Fiberglass can also aggravate preexisting conditions such as asthmaVerified Source Medline PlusOnline resource offered by the National Library of Medicine and part of the National Institutes of Health.View source and allergies.Verified Source Medline PlusOnline resource offered by the National Library of Medicine and part of the National Institutes of Health.View source

Technically, a mattress with fiberglass shouldn’t be irritating since it’s under the cover and not in contact with you. In other words, it can still be a comfortable mattress. Most companies tell you never to remove your mattress’s cover for this very reason.

Regardless, customers note how fiberglass can still escape from the cover, unzipped or not. With age, your mattress’s cover will wear down, and even the smallest tears can let the fiberglass out.

What If the Fiberglass Escapes?

Once out, cleaning up fiberglass on a mattress is difficult since the particles are so small. Fiberglass can contaminate your clothes, carpets, rugs, and other surfaces within your home—even your air conditioning! If the fiberglass particles spread far enough, you may need to toss a number of your clothes, bedding and other furniture or pay a professional cleaning service to salvage your home.

If you catch a fiberglass leak early enough, clean-up can be relatively simple.

1. Turn off the air conditioner if you have one. This keeps the particles from spreading through your ventilation system.
2. To prepare for clean-up, get a plastic trash bag and wear protective clothing, including goggles, thick work gloves, and a dust mask. If you can, find a mattress encasement or a mattress bag to close up the mattress, too.
3. Brush loose particles into the trash bag with a covered hand. A lint brush can also pick up any stray particles without direct skin contact. You can use the lint brush around the surrounding area to make sure you don’t miss particles, though a vacuum with a HEPA filter to pick up any lingering particles.
4. Once the fiberglass is cleaned up, then you want to completely encase your mattress to cover the leak. After this is done, we recommend disposing of the mattress as soon as you can.

You can avoid these issues and the potential hassle of clean-up entirely by simply not getting an online mattress with fiberglass. Less aggressive alternatives to fiberglass include wool, silica, and plant fibers.

How Do I Know If a Mattress Has Fiberglass?

Because fiberglass has developed a reputation as a less-than-desirable material, many manufacturers will try to obscure the fact that they use it as a flame retardant. A trustworthy brand with excellent customer service should directly answer the question of whether or not a mattress contains fiberglass, and what material they use as flame protection instead.

Non-Removable Cover

Instructions to not remove the cover isn’t necessarily a sign that a mattress contains fiberglass. There are concerns about removing the cover’s protection and directly exposing the mattress’s insides to allergens, moisture, and other things that can affect a bed’s feel. Removing the cover can even void a mattress warranty for these reasons.

However, a manufacturer may tell consumers not to remove a cover without elaborating on the reasons why because they don’t want owners to risk releasing the fiberglass inside.

Double-Check the Label

Reading the materials on the label can clue you into whether or not the mattress has fiberglass. Some manufacturers will try to use other terms for the material, like “glass fibers,” “glass wool,” or “glass-reinforced plastic” so keep an eye out for those.

Low Price

While a budget mattress can still be high-quality and even free of fiberglass, there is some truth to the idea that you get what you pay for. Because fiberglass is an inexpensive way to meet flammability standards, cheaper beds like those under $300 are more likely to rely on fiberglass for fire protection.

Read Customer Reviews

If you’re concerned about whether or not a mattress has fiberglass, you can look online to see what other customers and mattress reviewers are saying. Some mattress owners may complain online if fiberglass started leaking through the mattress as its materials wore out.

Now, some mattress manufacturers have made the switch from fiberglass to other materials, so it is important to keep that in mind as you browse customer reviews. A years-old complaint about fiberglass inside the mattress may no longer reflect what’s inside the current model.

Should I Buy an Organic Mattress?

If you want to avoid a mattress with fiberglass entirely, it’s difficult to deny the appeal of an organic mattress. Manufacturers who are committed to constructing an organic mattress will usually use wool or plant fibers in place of fiberglass, materials that are unlikely to cause irritation unless you’re allergic to them.

Common certifications that an organic or otherwise eco-friendly mattress has can include:

• GOTS (Global Organic Textile Standard)
• GOLS (Global Organic Latex Standard)
• Rainforest Alliance
• eco-INSTITUT
• GREENGUARD Gold

However, organic mattresses aren’t without their drawbacks. While their materials are eco-friendly and high-quality, the price tag for an organic latex mattress can be quite steep. You can expect to invest around $2000 or more for a queen size organic mattress.

Common Types of Mattresses

The type of mattress you choose can affect how comfortable it feels to you, along with whether or not it contains fiberglass. Some mattress types are more likely to contain fiberglass than others, though it is possible to find fiberglass-free mattresses with different materials.

Latex Mattresses

A latex mattress is the bed type most likely to be fiberglass free, as manufacturers tend to supplant an all-latex construction with other natural and organic materials. Latex foam is also highly contouring yet buoyant, easing tension through a gentle cushion without any uncomfortable sinkage.

Aside from its fiberglass-free construction, latex mattresses are also known for their material longevity. If you’re seeking one of the most durable mattresses on the market, it’s difficult to go wrong with a latex bed.

Memory Foam Mattresses

Memory foam mattresses are made with responsive polyurethane foam, a synthetic material that reacts to the heat and pressure of a sleeper’s body. It is often shortened to poly-foam. Memory foam is popular for its inexpensive construction that delivers high durability and full-body pressure relief.

While a memory foam mattress may contain fiberglass as a measure to keep the bed affordable, there are memory foam beds without fiberglass. Still, some shoppers prefer to look for mattresses without memory foam.

SEE ALSO: Are Memory Foam Mattresses Safe?

Innerspring Mattresses

Once the bedroom mainstay, innerspring mattresses are no longer the only type of mattress that shoppers can consider. Essentially, an innerspring mattress is a series of uncovered coils with cushioning materials on the top and bottom. While many low-cost budget innerspring mattresses do contain fiberglass, there are models with silica, wool, or flame-resistant plant fibers instead.

Hybrid Mattresses

Hybrid mattresses are a mix of foam and innerspring mattress qualities. They have a top of foam that’s at least 2 inches thick, with underlying wrapped coils for motion-isolating support.

Whether or not a hybrid mattress contains fiberglass tends to be tied to what its comfort material is. A latex hybrid mattress is likely to have an organic material like wool as a flame barrier, while a memory foam hybrid mattress may have fiberglass or another material.

Air Mattresses

A blow-up air mattress is a common choice of inexpensive bed when sleepers want something to keep on hand for guests or take with them on the road. There are a wide variety of airbeds, from low-priced ones that are essentially a sack of air to models that have multiple air chambers and various forms of smart technology.

An air mattress is unlikely to contain fiberglass, and that’s not just due to concerns about how glass particles might cause a leak in the casing. CPSC states that air mattresses do not have to meet mattress flammability standards unless “they contain upholstery material between the ticking and mattress core.”

Waterbeds

Like air mattresses, waterbeds are exempt from U.S. flammability requirements for mattresses unless they have upholstery material. So a waterbed is unlikely to contain fiberglass. However, waterbeds do draw other shopper concerns, such as the mess they create if they spring a leak and the lengthy set-up needed to fill a waterbed.

Choosing the Right Mattress Firmness

Perhaps the most important consideration when choosing a mattress is whether its firmness matches your sleep style. Your preferred sleep position and how much you weigh can affect how the mattress feels to you. Picking the right firmness can make the difference when it comes to the most comfortable mattresses versus a bed that feels unsupportive or hard like a plank.

“In studies of participants diagnosed with low back pain, prescribing an appropriate mattress type based on the individuals’ dominant sleeping positions has been found to decrease physical discomfort and improve sleep quality over 12 weeks,” says Dr. Tanaka.

Side Sleepers

When it comes to the three positions, most individuals will sleep on their sides. However, without the right mattress for side sleeping, the increased pressure can be placed on the shoulders and hips, contributing to morning aches and pains. A softer mattress is often necessary for side sleping comfort.

Ideally, a bed for side sleeping should be a soft to medium mattress. Soft mattresses are excellent for curvier sleepers who want ample amounts of cushion, while medium-soft to medium mattresses are good for sleepers who want a more supportive feel.

SEE ALSO: Soft vs. Medium Mattress

Back Sleepers

The upside of back sleeping is that it naturally mimics good posture, but you need a supportive mattress to make the most of this. A proper mattress for back sleeping offers a gentle amount of cushion with underlying support.

Medium-firm mattresses are popular choices with back sleepers. Some may go for a firm or medium mattress if they prefer more support or softness in their bed.

Stomach Sleepers

Many sleep experts recommend against sleeping on the stomach, largely because of the risk of misalignment. When you stretch out on your stomach and lie there for hours asleep, gravity can push your torso into the mattress, leaving you with a sore back in the morning. A mattress for stomach sleeping should offer a firm surface for unyielding support.

An extra firm mattress may provide the necessary support to help maintain proper spinal alignment, particularly for stomach sleepers. Though while a firmer mattress can minimize discomfort, shoppers may want to consider the benefits of another sleeping position.

Combination Sleepers

If you’re a combination sleeper, you move between two or all three sleep positions. Because of this, mattresses for combination sleepers should offer a medium to medium-firm feel to adequately suit all positions.

Heavier Sleepers

Sleepers who weigh more than 230 pounds will press down on a mattress more than the average sleeper does, which can create a softer-than-expected feel. They need the right mattress for heavy sleeping to avoid feeling like they’re lying on a sinkhole. We recommend shopping in the firmer end of the recommended range for your sleep position.

Lightweight Sleepers

If you’re an individual under 130 pounds, then you need the opposite of what a heavier sleeper needs. While a larger individual needs firm support, a mattress for lightweight sleepers need a softer feel to readily meet a smaller individual’s curves.

Choosing the Right Mattress Size

FAQs

Is fiberglass OK in a mattress?

Fiberglass in a mattress isn’t the end of the world, but it’s not great either. Coming in contact with fiberglass can irritate your skin, eyes, throat, and nose. Several symptoms include itchiness, coughing, stomach pain, sore throat or nose, and eye redness. While there aren’t any noted long-term effects of fiberglass exposure, these symptoms are best avoided.

Does every mattress have fiberglass?

While not all mattresses contain fiberglass, many do. In the United States, mattresses must contain some sort of flame retardant or barrier. This way, in the case of a fire, your mattress won’t erupt into flames and you have leeway to safely escape the area.

Fiberglass use is so common in mattresses because it’s a cheap and chemical-free flame retardant. If there were ever a fire, the fiberglass would melt on itself and the mattress rather than spreading the flames.

What kind of mattresses have fiberglass in them?

Any type of mattress can contain fiberglass, so it’s a matter of reading the fine lines and comparing specific brands.

All-natural latex mattresses are least likely to contain fiberglass. Memory foam mattresses, hybrid mattresses, and innerspring mattresses are more likely to contain fiberglass than a natural latex mattress, but this isn’t universal. Rather than fiberglass, brands will use wool, silica, or plant fibers as flame barriers.

How do I know if my mattress has fiberglass?

Mattress companies won’t advertise their beds as having fiberglass, so consumers are often left to figure this out for themselves.

Check the mattress’s label or its specifications online before you make a purchase. Words to look out for include the most obvious, “fiberglass,” but also words such as “glass wool” or “glass fibers.”

If your mattress’s instructions say “do not remove cover,” it likely means it contains fiberglass. Even if your mattress has a zipper cover and it says that, do not remove the mattress cover. The zipper was likely added as part of the manufacturing process, not as an easy way to clean it.

What mattress doesn’t have fiberglass?

When avoiding fiberglass, your best option is to shop for eco-friendly mattresses, such as organic latex mattresses. These types of beds most often contain wool as a flame barrier rather than fiberglass or silica.

Organic latex mattresses aren’t just good for safety reasons. They’re quite breathable, supportive, and durable on top of being safe to sleep on.

Conclusion

You don’t have to forfeit your comfort for your safety. There are countless mattresses free of fiberglass and now you have a list of the best ones. Beyond looking for fiberglass-free options, consider your firmness needs and mattress type preferences to help choose the right bed for you.
