We have affiliate relationships where we are paid a commission on sales through some of our links. See our disclosures.

Though used as a fire retardant in mattresses, fiberglass can be dangerous if exposed, which is why we’ve compiled this list of the best mattresses without fiberglass. In addition to being fiberglass-free, we made sure to include mattresses that can work for a wide variety of sleepers. We tested these beds in our own mattress lab to determine how well they do in categories like pressure relief, firmness, motion isolation, cooling, and edge support. No matter what your preference, we’re positive you’ll be able to use the information we’ve derived from our tests to find the best fit.

Our Top Pick for the Best Mattress Without Fiberglass

The Bear Original gets the top spot on this list since it’s not only 100 percent fiberglass free, but it also is a very supportive, high-quality mattress designed for relaxation and recovery.

Even though it’s made entirely of foam, the Bear has a firm, supportive feel that should be sturdy enough for back sleepers and stomach sleepers alike. Additionally, combination sleepers should be able to easily move around on its surface. You can also pay extra for a Celliant cover that may help with cooling and muscle recovery. Learn more in our video review.

What our tester says:

“I found the double poly foam construction produced a firm, supportive feel. Though you’re likely to sink into its top layer of memory foam, this sinkage is somewhat curbed by the taut poly foam transition layer. This means most folks are going to be positioned more “on top” of the structure than “in” it.” – Nichole Mondshein, lead reviewer and mattress tester

Expert Opinion

The Bear Original is one of the only mattresses made specifically with athletes in mind. The secret? Celliant material in the cover. Studies show that it can help with active recovery by promoting blood flow and oxygen to your tissues. While Sleepopolis cannot personally say if this cover helps with athletes’ recovery time, we can attest to the cooling tendencies. Celliant helps to regulate your temperature, which is great for hot sleepers, or couples who have double the body heat in one bed. However, we do want to be honest with our customers and share that this cover is not included in the overall price of the Bear Original. It must be added at check out for an additional $130.

When we tested out the Bear Original, we were struck by its firmer and supportive feel since it’s an all-foam mattress. We rated it a 7.5 on the firmness scale, which is created using the rankings of multiple Sleepopolis mattress testers. Because of this firm feel, the Bear Original gave us the sensation of sleeping on top of the bed, rather than sinking too far into it. That’s a mighty feat for a foam mattress, as foam beds usually tend to feel less supportive and durable than hybrid mattress or ones made from innersprings.

What our tester says: “First and foremost, I’d recommend the Bear to back sleepers in need of a firm bed. Stomach sleepers should also get the lift they need for their shoulders to stay neutrally aligned with their hips.” – Nichole Mondshein, lead reviewer and staff writer

What Customers Say

After looking at the Bear website, the majority of reviewers commented on how well this mattress works for their younger children who are involved in athletics. Other users commented on how surprised they were by the comfort of this mattress despite the low price of the Bear Original.

Pros of the Bear Original

  • The Bear Original is great for budget-friendly shoppers. Even before discounts, the Bear Original is priced under $1,000 for a queen-sized mattress.
  • The two-inch section of graphite gel-infused memory foam has a slow-response to pressure. This is great for sleepers with back or joint pain, who will appreciate the contour and pressure relief that this mattress provides.
  • With great motion transfer results, couples shouldn’t be able to feel the movements of their partner throughout the night. This is due to the top layer of memory foam included in the Bear Original, which keeps movement from spreading across the top of the mattress.

Cons of the Bear Original

  • Heavier sleepers (those over 250 pounds) may not find the support they need from the Bear Original. Instead, these sleepers might want to opt for an innerspring mattress, which they can find in our roundup of best innerspring mattresses.

Bear Original’s Fiberglass-Free Construction

Bear says on its website, “None of our mattresses contain fiberglass. We use 100% fiberglass-free, OEKO-TEX certified, flame-retardant rayon. It’s chemical-free, safe, and effective, so you can breathe easy at night.”

Helix has a line of six hybrid mattresses, each with a different level of firmness. The Midnight is one of their medium models. It has enough contouring for side sleepers, but should still be supportive enough for back sleepers, as long as they don’t mind a softer bed. Learn more in our video review.

What our tester says:

“I like the Helix Midnight Luxe for back sleepers and side sleepers. The medium-soft to medium-firm feel should give these folks the right balance of comfort and support.” – Nichole Mondshein, lead reviewer and mattress tester

Expert Opinion

The Helix Midnight Luxe is a hybrid mattress that features plush memory foam constructed over pocketed coils for a balance of pressure relief and support. This combination creates a medium-soft to medium-firm feel in the Helix Midnight Luxe that is especially important for both back and side sleepers. These sleepers need enough support to keep their spine in a neutral alignment. Luckily for them, the Helix Midnight Luxe includes an entire support layer of individually wrapped coils. This gives the mattress enough durability to keep sleepers lifted during the night.

However, back sleepers also need pressure relief around their lumbar region and shoulders. The comfort layer included in the Helix Midnight Luxe is made of memory foam, which helps to relieve added pressure around the joints and contour the body where it needs it most. This hybrid mattress also sleeps cool and has high breathability, offering an added bonus to sleepers that might suffer from night sweats, or to those who sleep with a partner and have double the body heat in their bed.

What our tester says: “I think back sleepers should be happy on the Helix Midnight Luxe. It offers a nice balance of pressure relief and support. I especially recommend this model if you struggle with back pain, as it offers a bit more lumbar support than the standard Midnight.” – Nichole Mondshein, lead reviewer and staff writer

What Customers Say

Many customers on the reviews section of the Helix website praised the Helix Midnight Luxe for its plush feel, with some comparing it to sleeping on a cloud. Other users also noted how well this mattress helped to alleviate their back pain, which many attributed to the pillow top included on the Helix Midnight Luxe.

Pros of the Helix Midnight Luxe

  • Sleepers who suffer from shoulder pain should feel comfortable on the Helix Midnight Luxe because it includes cushioning that prevents stiffness around the joints. This same cushioning also helps to relieve hip pain. However, side sleepers with hip pain might want to check out a softer mattress for more cushioning.
  • The Helix Midnight Luxe is also a great mattress for sex because of the bounciness of the individually wrapped coils included in its construction. This makes the bed easy to move around on.
  • The responsiveness also makes this a good mattress for combination sleepers who need to switch sleeping positions at night.

Cons of the Helix Midnight Luxe

  • Heavier sleepers (those over 250 pounds) most likely won’t get the support they need from the Helix Midnight Luxe because of how soft this mattress is. These sleepers will need to opt for a mattress designed for larger body types, which they might be able to find on our best mattresses for heavier sleepers page.

Helix’s Fiberglass-Free Construction

Helix says on its website that “Every Helix mattress is made without the use of fiberglass. All Helix mattresses are designed with a fire retardant yarn made from a chemical-free Rayon barrier that is in the form of a small foam layer. Rayon fiber is a manufactured fiber composed of 100% regenerated cellulose.”

“I’d recommend the Bear Elite Hybrid for most back and stomach sleepers.I think these sleepers will get the needed pressure relief and contouring around the lower back and hips. This mattress does a wonderful job at offering body contouring while still helping the sleeper stay elevated and lifted as well. The layers of foam should provide comfort while the coil system should offer lots of support.” – Nichole Mondshein, lead reviewer and mattress tester

Expert Opinion

Hybrid models have become really popular since their blend of materials offers the sought-after combination of support and pressure relief. When we tested out the fiberglass-free Bear Elite Hybrid — made with soft memory foam up top and sturdy coils at the bottom — we experienced all of the features that hybrids are known for: spinal support, a little bit of contouring, and plenty of cooling. We found it to be on the softer end, giving it a score of 6 out of 10 on our mattress firmness scale. That means the Bear Elite Hybrid is a bit plusher than most other beds, as the industry standard is set at 6.5 for a medium-firm mattress. 

One of the most unique things about the Bear brand is that it caters to athletes. Like several of its models, the Elite Hybrid has a cover made of Celliant, a material designed to promote muscle recovery and blood flow. While we haven’t independently verified these claims, Celliant has undergone several clinical trials that you can read about here. We can confidently say that the Elite Hybrid has strong edge support, due to a reinforced perimeter of coils. So athletes can easily spread out on their bed after a workout.

What our tester says: “I’d recommend the Bear Elite Hybrid for most back and stomach sleepers. I think these sleepers will get the needed pressure relief and contouring around the lower back and hips. This mattress does a wonderful job at offering body contouring while still helping the sleeper stay elevated and lifted as well. The layers of foam should provide comfort while the coil system should offer lots of support.” – Nichole Mondshein, lead reviewer and staff writer

What Customers Say

The Elite Hybrid is newer than some of the other Bear models, so there aren’t as many reviews for it on the company’s website (about 330 as of this writing). But the ones that are there praise the different firmness levels and how they’re able to accommodate every sleeping position.

Pros of the Bear Elite Hybrid Mattress

  • The Bear Elite Hybrid comes in three different firmness levels, so there’s something for every sleeping position. We think side sleepers will be most comfortable on the Soft model, back sleepers will be most comfortable on the Medium, and stomach sleepers will be most comfortable on the Firm.
  • Another bonus of Celliant is that it sleeps incredibly cool. Between that and the airflow-promoting coils, we think the Bear Elite Hybrid is an excellent pick for hot sleepers or anyone looking to cool down after exercising.
  • The Bear Elite Hybrid’s springs give it a lot of responsiveness. That means it should be easy for you to move around, making it a great mattress for combination sleepers who switch positions at night. Couples should also find that it’s a good mattress for sex.

Cons of the Bear Elite Hybrid Mattress

  • Being a luxury option, the Bear Elite Hybrid is on the expensive side — something to keep in mind if you’re shopping on a budget.

Bear Elite Hybrid’s Fiberglass-Free Construction

Bear says on its website, “None of our mattresses contain fiberglass. We use 100% fiberglass-free, OEKO-TEX certified, flame-retardant rayon. It’s chemical-free, safe, and effective, so you can breathe easy at night.”

Like the other Helix mattresses, it can be upgraded to the Luxe version if you’re willing to pay a little extra for luxury features. To learn more, check out our video on Helix mattresses.

What our tester says:

“I really appreciate how supportive these mattresses are. Stomach sleepers, back sleepers, and heavy people (those over 250 pounds) could all benefit from the firm feel of this bed.

Expert Opinion

Stomach sleepers usually require a lot more firmness and support than other sleeping positions. That’s because they put the most pressure on a mattress, and they need a bed strong enough to keep their hips from bowing into the layers and throwing their spine out of alignment. Fortunately, Helix has created a good match for them with the Helix Dawn.

The Dawn is one of six hybrid mattresses in the original Helix line, each one with a different level of firmness. When we tested it out, we scored it at a 7.5 out of 10 on our mattress firmness scale, which is indeed very firm. When turning over on our stomach, we felt lifted by the mattress’s layer of coils at the bottom. This tells us that stomach sleepers should feel supported on the Helix Dawn and, most importantly, comfortable.The overall durability of the mattress and how effectively it supports various weights and body types.

“I really appreciate how supportive this mattress is. Stomach sleepers, back sleepers, and heavy people (those over 250 pounds) could all benefit from the firm feel of this bed.” – Logan Block, former content director

What Customers Say

On Helix’s website, the Dawn has a little over 1,200 reviews and an average customer rating of 4.4 out of 5 stars. Unsurprisingly, several folks talk about how they love the mattress’s firmness and its resistance to sagging.

Pros of the Helix Dawn Mattress

  • Back sleepers should also be comfortable on the Helix Dawn, as long as they enjoy a firmer feel. The coils will help them maintain a neutral spinal alignment.
  • The Helix Dawn has a soft cover that’s breathable, and the coils leave plenty of room for airflow. Both of these features help the bed sleep nice and cool, which should appeal to hot sleepers.
  • Like all of the original Helix mattresses, the Dawn is available in a Luxe version. For an extra charge, you get upgraded features such as a Tencel cover and added pillow top.

Cons of the Helix Dawn Mattress

  • The Helix Dawn is probably too firm for anyone who sleeps strictly on their side. If this sounds like you, check out our best mattresses for side sleepers for other options.

Helix Dawn’s Fiberglass-Free Construction

The Birch Natural is a latex mattress utilizing individually wrapped coils for added support. This mattress specializes in cooling and responsiveness, and the firmer nature suits back and stomach sleepers well. Perhaps the most special part about this mattress is the material quality. Not only is the Birch organic, but it has also earned multiple certifications for safe production and materials. For more information, check out our video review.

What our tester says:

“One of my favorite things about the Birch is how cooling it is. I think any hot sleeper will be satisfied by this breathable bed. It’s definitely one of the most cooling mattresses available thanks to its wool and latex layers. These cooling materials also make it one of my favorite organic mattresses.” – Madison Schaper, Sleepopolis staff writer

Helix is known for its original lineup of hybrid mattresses, and they’ve since gotten into the organic game with the Birch. This is an 11-inch tall Talalay latex mattress that ranks at a seven on our firmness scale, making it slightly firmer than the industry standard. This mattress has a highly bouncy feel, which makes it a great pick for combination sleepers who need to be able to move on top of the mattress in order to switch into multiple positions throughout the night. The Birch is also a great mattress for sex because of this bouncy, responsive feel.

The Birch is constructed using organic cotton and wool fibers. It is Greenguard Gold certified, so this mattress wasn’t made using high levels of chemical emissions or volatile organic compounds. The quilted fibers in the Birch also make the material fire-retardant, which is great for a bed that does include any fiberglass in its construction.

What our tester says: “One of my favorite things about the Birch is how cooling it is! I think any hot sleeper will be satisfied by this breathable bed. It’s definitely one of the most cooling mattresses available thanks to its wool and latex layers.” – Madison Schaper, former Sleepopolis staff writer and mattress tester

What Customers Say

The majority of customers on the Helix website commented on how little back pain they had after spending a few nights sleeping on the Birch. Other users talked about how much they appreciated the natural materials used in the Birch, and Helix’s commitment to eco-friendly mattresses in general.

Pros of the Birch

  • The organic materials and pocketed coil system used in the construction of the Birch make it particularly breathable, which is great for both hot sleepers and couples who want to make sure they don’t wake up sweaty. The natural wool used in the Birch also prevents this mattress from trapping any body heat, adding to the cooling feel.
  • The Birch is great for lightweight sleepers who don’t want to “sink” into their mattress. Lightweight back and stomach sleepers should especially enjoy the Birch because it should keep them uplifted so their hips can stay in line with their shoulders, promoting a healthy spinal alignment.
  • The Birch is also a great mattress for sleepers who suffer from back pain because of its results on our pressure map. While on our back, the results lit up entirely blue during the pressure map test (meaning low pressure), so sleepers with back pain should be comfortable.

Cons of the Birch

  • Sleepers suffering from hip pain will need a softer mattress than the Birch. The longer you lay on this mattress on your side, the more pressure digs into your shoulders and hips, which can be seen during the pressure map test. Because of this, side sleepers with hip pain might want to check out our roundup of the best mattresses with pillow tops to get some added pressure relief for their joints.

Birch’s Fiberglass-Free Construction

The company says they don’t rely on plastics or fiberglass materials for the fire-retardant layer in their mattresses. “There are numerous benefits of wool in our organic mattresses. Not only is it extremely comfortable, but wool fibers also provide a natural insulator so your body temperature stays regulated, and you stay asleep all night,” its website says. “In addition, our wool is naturally flame-resistant which makes it one of the safest fire-safety fibers to use in a mattress.”

The Emma Hybrid Comfort is a firm mattress with a durable hybrid construction. It works well for heavyweight stomach and back sleepers, as it provides enough support to keep these sleepers’ spines in neutral alignment. In addition to making it a good choice for heavier people, the Emma Hybrid Comfort’s design also gives it nice breathability and responsiveness, meaning it stays cool as you sleep and is easy to move around on.

What our tester says:

“After five minutes of lying on the Emma Hybrid Comfort, it increased 7.7 degrees. This indicates good temperature regulation. I really did feel cool when resting on it. Considering this, the airy hybrid construction, and the additional cooling features, I feel that the Emma Hybrid Comfort is one of the best cooling mattresses.” – Amelia Jerden, senior staff writer

A Note On Weight and Body Type

We recognize that people come in all shapes and sizes, and people of every size deserve a mattress that works for their body type. We use the weight categories light, average, and heavy to more easily categorize sleepers based on how mattresses will perform for their body type, as most mattresses are designed for the group we call “average” (130 to 250 pounds). We consider heavy sleepers to be anyone over 250 pounds, and they tend to need more support to prevent them from sinking too far into the layers.

Expert Opinion

The Hybrid Comfort is one of the newest fiberglass-free creations from Emma. With three sturdy layers, it’s built with cooling foam, firmer high-density foam, and a base of ergonomic coils that are supportive enough to hold up heavier weights over 250 pounds. We also ranked it at a 7.5 on our firmness scale, so it’s firmer than most other beds on the market. However, heavier sleepers should also get pressure relief in addition to stability and durability.

Couples should also appreciate the construction of this mattress, since a bed with two people is going to need extra support. Luckily, the Emma Hybrid Comfort is specifically designed with solid edge support. Our Sleepopolis testers did not feel any sagging or sinkage when they laid at the edge, which is great for couples who like to spread out and use the entire surface area of their mattress.

What our tester says: “Heavier sleepers who sleep on their back or stomach should sleep well on this mattress since it’ll keep their back and hips properly aligned with their spine.” – Amelia Jerden, senior product editor

What Customers Say

The Emma Hybrid Comfort is a brand-new mattress, so there aren’t a whole lot of customer reviews on the brand’s website just yet. However, the ones that are there praise the company’s expedient delivery and 365-night trial.

Pros of the Emma Hybrid Comfort Mattress

  • Sleepers with back pain should appreciate the Hybrid Comfort’s support, which will help keep their spine in alignment during the night.
  • The Emma Hybrid Comfort did well on our responsiveness test. It should be easy to move around the mattress, which is great news for those wanting a good mattress for sex or combination sleeping.
  • Couples should appreciate the Emma Hybrid Comfort’s motion transfer results. With good motion isolation, couples shouldn’t feel the tossing and turning of their partner during the night.

Cons of the Emma Hybrid Comfort Mattress

  • While heavy back sleepers and stomach sleepers should be happy on the Emma Hybrid Comfort, strict side sleepers with joint pain will want to go for a softer mattress in order to get more pressure relief around their hips and shoulders. Take a look at our roundup of the best mattresses for hip pain.

Emma Hybrid Comfort’s Fiberglass-Free Construction

When we reached out to Emma via email about whether or not their mattresses contain fiberglass, this was their reply: “Rest assured that the Emma Hybrid Comfort mattress does not contain fiberglass. We prioritize the use of high-quality and safe materials to ensure your comfort and peace of mind. Instead of fiberglass, we utilize alternative materials in our construction to provide you with the support and comfort you expect from an Emma mattress.”

The Nolah Natural is made with eco-friendly Talalay latex and supportive coils. This mattress has GOTS (Global Organic Textile Standard) organic wool, cotton, natural latex, and recycled steel. The latex makes this mattress responsive, which is great for couples and combination sleepers. This material is also naturally hypoallergenic and cooling, which can help hot sleepers prevent overheating. For more information, watch our video review.

What our tester says:

“It has a very soft, plush feel that provides you some cushioning as well. I’d say you’re going to feel more “on top” of this bed than “in it” — thanks to its bouncy latex.” – Bridget Chapman, former senior product editor.

Expert Opinion

The Nolah Natural is an 11″ mattress made from natural materials, which is especially important for eco-friendly shoppers. This hybrid mattress is hypoallergenic and includes GOTS (Global Organic Textile Standard) certified organic wool, GOTS certified organic cotton, recycled steel, and Talalay latex in its construction. It ranks at a 6 on our firmness scale, making it slightly softer than the industry standard of 6.5 for medium firmness.

The cover of the Nolah Natural includes organic wool that’s moisture-wicking and creates a natural fire barrier. This is especially important for a mattress that does not contain any fiberglass. The hybrid construction of the Nolah Natural also allows for more airflow throughout the mattress, helping with breathability and preventing the build-up of body heat.

What our tester says: “I felt so cozy on the Nolah Natural. Its two layers of latex kept me propped up and supported, but also offered some nice contouring around my joints. I think combination sleepers could really enjoy this bed too since it’s easy to move around on.” – Bridget Chapman, former senior product editor

What Customers Say

Many folks on the Nolah website commented on how much they appreciate a mattress made from entirely eco-friendly materials. Other users stated that the Nolah Natural was more comfortable than hotel mattresses that they have slept on in the past.

Pros of the Nolah Natural

  • Heavier sleepers that prefer to sleep on their side or back should enjoy the support and pressure relief that the softness of the Nolah Natural offers.
  • Sleepers with back pain should appreciate the pressure relief that the Nolah Natural offers. Our Sleepopolis mattress testers spread a pressure map over the bed and lay in different sleeping positions, showing how much pressure is exerted on the mattress. For back sleeping, the pressure map was completely blue (meaning low pressure).
  • Since the Nolah Natural includes coils and latex in its hybrid construction, it is a good mattress for sex because it is bouncy and responsive to movements on top of the bed.

Cons of the Nolah Natural

  • This is a soft mattress, so strict stomach sleepers will want to opt for a firmer mattress that will keep their hips lifted in line with their shoulders, promoting a healthy spinal alignment. Take a look at our best mattresses for stomach sleepers to find a firmer mattress.

Nolah’s Fiberglass-Free Construction

The company says on its website, “Nolah is committed to our customers’ comfort and safety, and all our mattresses are 100% fiberglass-free. Rigorous testing and strict certifications demonstrate the safety of all materials used in our mattresses. Our AirFoam™ mattresses (Nolah Original, Signature, and Evolution) are CertiPUR-US® certified and free from ozone depleters, heavy metals, and chemical fire retardants. Our latex hybrid mattresses (Nolah Natural and Nurture) are Global Organic Textile Standard (GOTS) and OEKO-TEX 100 Class 1 certified; they test free of harmful chemicals and substances.”

What our tester says:

“First and foremost, I’d recommend this mattress to hot sleepers. This bed sleeps nice and cool thanks to special phase change technology and gel infusions. The Aurora Luxe is also a nice pick for back sleepers. This mattress in the Medium model is medium-soft, so it should contour the hips while also lifting them into alignment.” – Nichole Mondshein, lead reviewer and staff writer

Expert Opinion

No one wants a mattress that traps heat so easily that they wake up hot and sweaty. During testing, we discovered that the Brooklyn Bedding Aurora Luxe is one of the finest cooling mattresses on the market. It has a cover made with Phase Change Material (PCM), which works to regulate your body temperature. We found that this fabric is quite literally cool to the touch. Beneath is a comfort foam built for pressure relief; this also contains more PCM for even more cooling. The support layer of pocketed coils at the bottom of the mattress allows for plenty of airflow. There’s also an optional Cloud Pillow Top offered for an additional fee, which can be helpful for those who sleep extra hot or those who need a lot of pressure relief.

There are also three separate firmnesses shoppers can choose from: Soft, Medium, and Firm. So, you can select the bed that’s best for your body weight and sleeping preferences. For what it’s worth, we tested the Firm.

What Customers Say

The majority of reviews on the Brooklyn Bedding Aurora Luxe website talk about the overall good value. Some think the Aurora Luxe is a bit expensive, but state that for the luxurious features and high level of comfort, it’s a fair price.

Pros of the Brooklyn Bedding Aurora Luxe

  • The Brooklyn Bedding Aurora Luxe is a great mattress for sleepers suffering from back pain. The top layer of foam included in the construction of the mattress helps to keep the spine in a neutral position, while also filling in the added space around the lower back. Additionally, the sturdy coils give extra support to the mattress.
  • Back sleepers with hip and shoulder pain should find adequate pressure relief on this mattress.
  • The Aurora Luxe is a great mattress for couples, as it scored well in motion isolation, responsiveness, cooling, and edge support.

Cons of the Brooklyn Bedding Aurora Luxe

  • Most back and stomach sleepers over 250 pounds might find that the Brooklyn Bedding Aurora Luxe isn’t supportive enough. Instead, they should opt for one of the mattresses on our roundup of the best mattresses for heavier sleepers.

Expert Opinion

You can probably guess from the name alone that the Plank is one of the firmest mattresses out there. Created by Brooklyn Bedding, it’s made entirely of foam and has a flippable design, with both a Firm side and an Extra-Firm side. You can turn it over to see which one is most comfortable for you, or even alternate between sides depending on the night.

When testing out the Plank Firm, we scored the Firm side a 7.5 out of 10 on our mattress firmness scale and the Extra-Firm side an 8.5 out of 10. Those scores are impressive for a foam bed, as these types of mattresses are often on the softer end. But the Plank Firm uses a thick layer of something called TitanFlex foam — a proprietary material that’s a lot denser (and of course, firmer) than standard memory foam.

What our tester says: “I think the Plank Firm is one of the best mattresses for stomach sleepers. Both sides of the mattress, the firm side and extra firm side, should give these sleepers the support they need to keep their hips in line with their shoulders.” – Nichole Mondshein, lead reviewer and staff writer

What Customers Say

On the Plank Firm website, customers rave about the mattress’s firmness. Granted, you have to prefer a firm bed to really enjoy it, but if you do, they say the Plank Firm can’t be beat.

Pros of the Plank Firm Mattress

  • Stomach sleepers should be comfortable on both sides of the mattress, depending on how firm they like their bd. Both sides are going to keep their hips lifted and in line with their shoulders, which is key to preventing back pain.
  • Back sleepers are also a good match for the Plank Firm, although we recommend they use the Firm side rather than the Extra-Firm side.
  • Heavier sleepers (those over 250 pounds) should appreciate the Plank Firm. It’s rare that a foam mattress can accommodate these folks, but they should get the firmness and support they need.

Cons of the Plank Firm Mattress

  • The Plank Firm is almost certainly going to be too firm for most side sleepers. They need more pressure relief on their hips and shoulders, which they will likely not receive from this mattress, since a lot of the pressure map test lit up yellow and red (meaning high pressure) in this position. Take a look at our roundup of the best mattresses for side sleepers for some better options.

Plank Firm’s Fiberglass-Free Construction

John Merwin — the CEO of Brooklyn Bedding’s parent company, 3Z Brands — speaks on behalf of all 3Z mattresses (including the Plank Firm): “Instead of spraying on fire retardant chemical sprays, we ensure that all 3Z Brand mattresses are fire safe and fiberglass free by using fire resistant fabric quilted into the mattress panels or by casing our foam in high quality fire retardant socks.”

What Is Fiberglass?

Fiberglass is often used in mattresses as a flame retardant and is meant to be safe, but many people are wary of having it in their beds since it can cause health concerns if exposed.

Because it’s a common and inexpensive material for manufacturers to use, finding the best mattress without fiberglass is not always an easy task. For that reason, we’ve put together this roundup of the best mattresses without fiberglass.

If you’d like to learn more, please check out our guide on fiberglass for more information.

Expert Opinion: What Are the Health Risks of Fiberglass Exposure?

“Exposure to fiberglass can irritate your skin, eyes, and lungs, causing issues like itching, coughing, allergic reactions, and even breathing difficulties.” – Dr. Raj Dasgupta MD, FACP, FCCP, FAASM. Quadruple-board certified in pulmonary, sleep, internal, and critical care medicine

How to Check if a Mattress has Fiberglass

Although it can be safe if used properly, many consumers are looking to avoid the material altogether. Here are some quick ways to check if a mattress contains fiberglass.

Search for Organic Materials

Companies will often use organic and hypoallergenic materials, like cotton or wool, in the fire barriers of mattresses instead of fiberglass. Be on the lookout for certifications like CertiPUR-US, GOLS Certified (Global Organic Latex), GREENGUARD Gold Certified and more to make sure the mattress materials are organic and up to standard.

Ask the Manufacturer

If it’s not clearly stated on their website, you can ask a mattress company representative via online chat or phone whether or not they use fiberglass in any form in their beds. Fiberglass is also referred to as glass fiber or glass wool sometimes, so make sure the company’s being transparent.

Check the Mattress Label

It’s required for every new bed to have a tag that states all the materials used in it. Most fiberglass-free mattresses will state it clearly on the label and we have made sure to only select beds without fiberglass in this lineup.

Avoid the Cheapest Option if Possible

Of course, budget is a huge factor when selecting a mattress. Since fiberglass is appealing to companies for its low cost, it’s often used in less expensive beds. A good rule of thumb is to double-check the mattress tag. There are several fiberglass-free mattresses out there that will fit the budget. Some affordable fiberglass free brands to look out for includes Bear & Brooklyn Bedding.

Pro Tip: Trust Your Gut

If a company is dancing around the question, not being straightforward and not stating its fiberglass percentage, trust your instincts and perhaps take your business elsewhere.

What to Consider When Buying the Best Mattress Without Fiberglass

Thanks to some recent high-profile lawsuits, the use of fiberglass in mattresses has made headlines recently. So… is it safe to actually use in mattresses? Yes – but there are a few caveats.

Why Use Fiberglass?

Mattress companies will often use fiberglass as a flame retardant since it meets safety standards and is a cheap option compared to other alternatives.

Fiberglass may prevent a mattress from bursting into flames if it catches fire and will lead it to slowly burn instead. However, it’s essential for fiberglass to be completely concealed in a mattress and never be exposed to sleepers. However, if a mattress is poorly made or becomes damaged, the fiberglass may be released. If you’re exposed to fiberglass, it can damage your eyes, skin, upper respiratory tract, and lungs. It’s also very difficult to clean up once it’s released into your environment.

Mattress Types

Sleepopolis testing of mattress materials
Take a Closer Look at the Different Mattress Materials

Although they share the commonality of not containing fiberglass, you may have noticed that we’ve included several different types of beds in this roundup. Let’s go over their differences.

  • Foam: All-foam mattresses are made entirely of foam layers and tend to offer great pressure relief. They can be less expensive, but also less durable.
  • Innerspring: Innerspring mattresses are a little more “old school” and used to mainly consist of just springs and fabric in their construction. Nowadays, innerspring mattresses usually have a good bit of foam in the construction as well. They tend to be very responsive and supportive. 
  • Hybrid: A hybrid mattress is built with a combination of different materials — usually foam and coils. They’ve become very popular in the mattress market since they often have a balanced, medium-firm feel.
  • Latex: A latex mattress is made with latex foam derived from either Talalay or Dunlop latex. Latex is bouncy, responsive, and cooling. It’s also really durable. A lot of latex mattresses combine the latex with other materials, like coils or polyurethane foam.

Fiberglass Alternatives

A few alternatives to fiberglass that we see in mattresses include wool, cotton, polyester and rayon. These are all flame retardant materials like fiberglass however offer more comfort, are better for the environment and our health. Brands like Saatva use a plant-based thistle as an alternate to fiberglass and other brands like Big Fig use a blend of cotton and other organic materials in its original mattress. 

Sleeping Position

Here’s a brief overview of what mattresses might be good for the different sleeping positions.

  • Back sleepers: These sleepers don’t tend to need too much from their bed and mainly need their bed to be comfortable and supportive. They usually do best on hybrid or innerspring mattresses.
  • Side sleepers: Side sleepers tend to need a softer mattress in order to get nice cushioning and pressure relief for their shoulders and hips. They typically do well on foam mattresses, although they can also find a match in many hybrid beds.
  • Stomach sleepers: Stomach sleepers need a firmer and more supportive mattress in order to keep their hips lifted and in line with their shoulders — ensuring healthy sleep posture. We usually steer stomach sleepers toward innerspring mattresses, although there are some hybrids that can work well for them.
  • Combination sleepers: This refers to sleepers who switch positions throughout the night. They need a responsive bed that allows them to easily move around and change sleeping positions. They typically do well on latex mattresses, hybrid mattresses, and innerspring mattresses. 

Body Types

At Sleepopolis, we categorize lightweight sleepers as weighing less than 130 pounds, average-weight sleepers as weighing between 130 and 250 pounds, and heavy sleepers as weighing more than 250 pounds.

How Body Type Can Make a Difference

Beds are typically going to feel firmer to lightweight sleepers than they do heavyweight sleepers. If you’re heavier in weight, you’re also going to need more support from a bed.

We typically recommend heavier sleepers look for an innerspring mattress or on our roundup of the best mattresses for heavy people. This list consists of beds built especially for larger folks. When looking for fiberglass-free mattresses for heavy sleepers, prioritize support and durability with high-density foam or sturdy innerspring coils. Choose options that offer good comfort and pressure relief, ideally medium to firm, to ensure proper spinal alignment. Lastly, check for safe materials and certifications like CertiPUR-US to confirm the absence of fiberglass.

Firmness

Your body type and preferred sleeping position are crucial considerations when selecting a mattress, and its imperative to keep both in mind when deciding the perfect firmness to you.

The mattress industry tends to measure firmness on a scale of one to 10, with one being the softest and 10 being the firmest. We categorize a mattress with a 6.5 out of 10 score as medium-firm, meaning it possesses the most even balance of comfort and support.

Softer mattresses (3 to 6 out of 10 on our scale) are typically best for side sleepers, those with joint pain, and lightweight folks. Medium-firm beds (6.5 out of 10) typically benefit back sleepers, average-weight sleepers, and combination sleepers best.

Firmer beds (7 out of 10 or more) do best at supporting most stomach sleepers and heavier folks to press through more of the mattress materials. For an in-depth walkthrough, see our official Mattress Firmness Guide.

Durability of Fiberglass-Free Mattresses

Fiberglass-free mattresses tend to be more durable than those containing fiberglass, as they often utilize higher-quality materials. Experts suggest that mattresses made from natural latex or high-density memory foam can last 10 to 15 years, while lower-quality options may only last 5 to 8 years. In contrast, mattresses with fiberglass may degrade more quickly, leading to potential comfort issues over time. Materials like natural latex and high-density polyfoam are known for their longevity, whereas traditional, cheaper memory foam may be less durable if of lower density. Overall, investing in a quality fiberglass-free mattress can enhance both durability and long-term comfort.

Cooling

Just because you’re priority is a fiberglass-free mattress, that doesn’t mean you should miss out on other critical mattress features. A well temperature regulated mattress will improve your sleep tremendously by helping you sleep better through the night. When testing each mattress in our studio, we use a thermal temperature control gun to help us understand where each mattress holds the most amount of heat.

Our testers lay for several minutes on the mattress and then measure how long it takes the mattress to go back to its original temperature. We consider an 8 degree change or under to be good cooling, and a change of 5 degrees and under to be great cooling.

Motion Isolation

If you’re looking for a fiberglass free mattress but also want this bed to work for you and your partner, and/or kids, or pets, motion isolation is a crucial factor you should think about. Motion Isolation refers to the amount of movement that is felt across the mattress when the person laying next to you changes position or gets into and out of bed.

We test the motion isolation for each mattress in a couple different ways. First we look use a drop ball test in which we drop steel balls from different heights and use a seismograph to measure the movement felt across the bed. The bigger the ripple, the worse the motion isolation. Another clear cut way we test this out is with our red wine test. We put a full red wine glass on the bed while one of our testers lays on the other side in various positions. A mattress that keeps the glass up has fantastic motion isolation. In general, we find that foam and hybrid mattresses have the best motion isolation because of their medium-firm nature so keep that in mind when looking at fiberglass free mattresses. 

Hear From the Expert: Would You Recommend That Sleepers Buy a Fiberglass-Free Mattress Rather Than One That May Contain Fiberglass?

“Yes, it’s a good choice to pick a fiberglass-free mattress to avoid the health problems associated with having exposure to fiberglass. Choose mattresses that explicitly say they are fiberglass-free, or look for materials like natural latex or organic cotton, both known for offering exceptional safety and comfort when it comes to mattresses.” – Dr. Raj Dasgupta MD, FACP, FCCP, FAASM. Quadruple-board certified in pulmonary, sleep, internal, and critical care medicine

Edge Support

Edge support in a mattress refers to how well the edges resist compression when weight is applied, allowing sleepers to use the entire surface without feeling like they’re rolling off. It’s especially important for heavier sleepers, seniors and those who tend to sit on the edge, as it helps maintain stability and prevents sagging. Fiberglass-free mattresses often perform well in edge support, particularly those with high-density foam or sturdy innerspring coils. For optimal edge support, natural latex or hybrid beds are a top choice, as it provides excellent resilience and firmness at the edges. This combination ensures a comfortable sleep experience while maximizing the usable surface area of the mattress. We test edge support by sitting on the edge of the bed and using a yard stick to measure how much sink is experienced by our testers.

Sleep Trials & Returns

When buying your new fiberglass free mattress, make sure to look out for the brands warranties, return policies and sleep trials. Typically, we recommend testing a mattress for 30 days to see how our body adjusts to it. Most brands have a 60-90 day sleep trial period which allows you to determine if you want to keep it with no financial burden if you choose to return it.

Mattress Warranties

The warranty of your mattress is how long a mattress company is willing to ensure the durability of your mattress and generally means that if something happens to the mattress within that time frame, that they will replace it free of charge. Many companies offer a 10-year warranty, while others offer life-time warranties.

Keep in mind, typically the higher your price-point of mattress, the better the policies. All the brands we have chosen offer great company policies and we feel very comfortable recommending them to you. 

What are the Risks of Fiberglass?

Fiberglass isn’t dangerous unless exposed. If a mattress has fiberglass exposed, it could cause skin irritation, respiratory issues and larger issues if exposed for a long time. This often isn’t an issue in mattresses unless you take off the cover which can release those glass particles in your environment. Keep in mind, we have primarily only seen fiberglass in the mattress covers, so be sure to not remove covers unless you know its a fiberglass free mattress like the ones we have picked here. Check out our guide on What you Need to Know about Fiberglass for more information. 

FAQs

What is fiberglass?

Fiberglass is a composite material made of glass and reinforced plastic. It’s used in a variety of products and places, from wall insulation to mattresses. It’s known for being very malleable, durable, and inexpensive, which is why manufacturers like to use it.

Do all mattresses have fiberglass?

No. Not all mattresses contain fiberglass. However, many do, as it’s an effective flame retardant. Fiberglass is less expensive than a lot of other options out there, which is why many companies use it.

Is fiberglass dangerous?

Fiberglass is really only dangerous if you’re directly exposed to it. If it remains beneath your mattress cover (or perhaps under a mattress protector as well), you shouldn’t have a problem with it. The issues arise when a poorly made or damaged mattress releases the glass fibers and humans come into contact with them. If this happens, the fiberglass can irritate or cause damage to people’s eyes, lungs, upper respiratory tract, or skin.

Is fiberglass in mattresses illegal?

No. It meets the federal safety standards for open-flame fire resistance in mattresses. However, it’s supposed to be completely contained and covered when it is used in beds.

Should I only purchase mattresses without fiberglass?

That’s up to you. Fiberglass can be safe to have in a mattress if it’s properly concealed, but some consumers prefer to forgo any risk of being exposed to it and buy a mattress without fiberglass instead.

What do I do if my mattress has fiberglass?

It’s important to never remove your mattress cover if the bed contains fiberglass. We also recommend adding a mattress protector to your bed for extra protection. If your bed is showing wear and tear, it’s a good idea to replace it. If its exterior is still in good shape, a good rule of thumb is to replace a mattress after five to 10 years.

Do most memory foam mattresses have fiberglass?

Most budget friendly memory foam mattresses contain fiberglass however fiberglass isn’t limited to just memory foam mattresses. The more money you spend on your mattress the less likely it has traces of fiberglass.

How We Chose These Mattresses

Our team of Certified Sleep Science Coaches has reviewed more than 300 products in Sleepopolis’ mattress lab, running each one through tests such as pressure-mapping and measuring motion transfer with a seismometer. From there, we give every bed an overall score based on materials, comfort, support, cooling, and edge support. We also factor in brand performance with categories such as value and warranty.

For the mattresses on this page, we made sure they don’t use fiberglass in any form (or under any name) in their materials. Instead, they commit to being fiberglass-free and use other flame-retardant alternatives, like cotton, wool, rayon, latex, and proprietary blends. Click here to learn more about our methodology.
