Based on our firsthand experience and investigations, fiberglass is not an uncommon material when it comes to mattress production, with many brands using it as a fire sock. All mattresses manufactured in the USA must be able to withstand fire to a certain degree. This precaution is meant to keep consumers safe in the worst-case scenario.

However, fiberglass isn’t without its drawbacks. Our research indicates that if sleepers are exposed to the fiberglass particles within their mattresses, they may develop skin irritation or breathing difficulties. Fiberglass can also be difficult to clean out of a bedroom once it’s free of a mattress.

Our findings show that not all brands use fiberglass in their mattresses. However, the material is popular enough that finding a bed free of fiberglass can take laborious effort.

Using our accumulated practical knowledge and years of mattress testing experience, we’ve rounded up our top recommendations to streamline your mattress shopping experience and help you avoid fiberglass-related issues.

Based on our firsthand experience, Amerisleep’s line-up of mattresses provides a diverse range of options, with soft to firm mattresses and everything in-between. The company is also committed to offering excellent, sustainable, safe comfort with their memory foam mattresses. Every single foam inside their numbered line of mattresses is certified safe by CertiPUR-US®, a third-party agency that analyzes foam production processes.

When we trialed their products, we found that Amerisleep also offers mattresses that are free of fiberglass. Including their top mattress seller, the Amerisleep AS3. This model is their most commonly chosen mattress because of its medium feel surface, cushioning the body’s sensitive areas and supporting the back to prevent misalignment in most positions.

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

There are three layers of foam inside the AS3, and all of them are wrapped inside Amerisleep’s exclusive Refresh cover fabric. This fabric goes beyond maintaining a cool surface temperature, as its weave includes minerals that convert heat into infrared energy. By releasing this transformed infrared energy, the AS3 promotes greater local recovery in the sleeper’s body.

The first foam layer of the AS3 is a plant-based memory foam known as Bio-Pur®. Instead of relying entirely on traditional synthetic ingredients, Amerisleep replaces a select portion with plant-derived oils for a more eco-friendly foam. After testing this mattress out, we found that Bio-Pur® is also naturally cool and swifter to adapt to movements than traditional memory foam.

The second foam layer of the AS3 is Affinity foam, a responsive material for smooth transition. Across the surface of the Affinity foam are several hexagonal cutouts, making up the mattress’s HIVE® targeted supprot technology. We have found from using this product that HIVE® ensures the mattress feels soft where it’s wanted and firm where it’s needed.

The third and final foam layer of the AS3 is Bio-Core® foam, a sturdy material that inspired Amerisleep’s lengthy mattress warranty. Based on our observations, Amerisleep is confident that sleepers can get more than a decade of use out of a well-maintained mattress thanks to Bio-Core®.

The Amerisleep AS3 ships free and comes with a 100-night sleep trial and a 20-year warranty.

Zoma builds its mattresses with a focus on promoting recovery, and as part of that mission, their original Zoma Hybrid is now fiberglass-free. Many professional athletes have enjoyed sleeping on the Zoma Hybrid. But as our tests of this mattress showed, you don’t have to be a big-name sports star to reap the benefits of the bed. its benefits can be unlocked by just about anyone. That’s why it’s our runner-up pick for the best mattress without fiberglass.

“Studies have shown that sleep quality can affected by skin temperature, and the thermal properties of bedding that can influence cooling have been shown to play an important role in this,” says Dr. Tanaka.

Four layers make up the Zoma Hybrid, and all foam layers are certified by CertiPUR-US®. Based on our firsthand experience, we can attest to the quality of the foam used in this mattress.

The first foam layer is gel memory foam, providing excellent pressure-relief and a stay-cool feel all night long. The second foam layer is Reactiv™ foam, a buoyant transition material. Our investigation demonstrated that Reactiv™ helps the mattress adapt to movements and keeps sleepers from ever feeling trapped in bed.

The Zoma Hybrid’s third and final fourth layers consists of pocketed coils on a firm foam base. By wrapping the coils inside the mattress, Zoma ensures that not even big sweeping motions will transfer across the surface, helping couples sleep better.

The base foam was engineered by Zoma to help the coils stand strong even after years of sleepers lying down and moving across the mattress, providing unbeatable support.

The Zoma Hybrid includes free shipping, a 100-night sleep trial, and a 10-year warranty. Based on our observations, we highly recommend this mattress for anyone seeking a restorative, fiberglass-free sleep experience.

  • Budget shoppers

Affordability can be a significant obstacle to overcome when you’re shopping for a mattress without fiberglass. Because most mattresses that contain alternatives are latex beds, shoppers typically have to expect to invest a significant amount for the peace of mind that comes with sleeping on a fiberglass-free mattress. Enter our top recommendation, the Zoma Start.

We determined through our tests that the Zoma Start is an excellent choice for people who are sensitive to latex or would simply prefer a mattress with memory foam. This is because many memory foam mattresses rely on fiberglass for their fire barrier, but the Zoma Start does not.

Plus, the mattress comes at extremely low prices. Most sizes cost under $500, putting the mattress within reach of most shoppers.

Underneath the mattress’s ventilated mesh AirCloth cover, we found that there is an inch of gel memory foam that absorbed body heat and transported it away from the sleeper to escape the mattress entirely, providing cooling comfort. Our investigation demonstrated that preventing heat build-up helped individuals sleep longer and better.

The next layer is the mattress’s transition foam, the aptly-named Reactiv™ foam. As we mentioned earlier, our finding show that the purpose of  Reactiv™ foam is to limit the sinkage that can cause discomfort and misalignment. Thanks to Reactiv™, sleepers will never feel “stuck” in bed.

The mattress’s base is a thick layer of Support+ foam, created to extend the mattress’s expected lifespan and maintain a sleeper’s healthy spine alignment.

The Zoma Start is backed by the guarantee of a 10-year warranty.

While not every size of the Helix Midnight mattress is under $1000, it offers plenty of options for single sleepers who want a touch of luxury in their mattress. The Midnight mattress is primarily designed for side and combination sleepers.

A few reviewers noted they had to try the Helix Midnight after they heard about it from someone else or after lying on a friend’s mattress. A couple of reviewers also noted that there was an adjustment period of a few days, but overall they found the bed comfortable and supportive.

The mattress cover fabric is Soft Touch, which lives up to its name by adding a touch of plushness that’s perfect for side sleepers. It’s light and stretchy, woven to enable breathability. Sleepers who want more coolness can upgrade to the GlacioTex cover fabric.

The first layer is Memory Plus Foam, created to boost pressure relief. Underneath this memory foam layer is high-grade polyfoam to serve as transition, limiting sinkage.

The main support core is pocketed coils resting on DuraDense foam. The coils cradle the body, while the sturdy base foam creates a stable foundation for a strengthened structure.

  • Pocketed coils with side support
Recommended For
  • Hot sleepers
  • All sleep positions
  • Budget shoppers and bargain hunters

Based on our firsthand experience, the Vaya Hybrid offers one of the most comfortable experiences that a budget shopper can find. Unlike many inexpensive mattresses, the Vaya Hybrid is fiberglass free, and delivers so much more than just a low price point. Our investigation found that the comfort of cotton, conforming foams, and pocketed coils come together to upgrade your comfort without breaking the bank.

As indicated by our tests, the versatile medium feel of the Vaya Hybrid quickly adapts to most sleepers as they stretch out across its surface. Drawing from our experience, there’s plenty of room for side and petite sleepers to gently sink in and feel embraced by their bed, but back and heavier sleepers can still feel buoyed by the pocketed coil core.

Reducing motion can be helpful for sleep when sharing a bed, as this has been associated with worse objective measures of sleep,” says Dr. Tanaka.

The top of the hybrid mattress is a quilted knit cover with an underlying 2 inches of cotton, providing a pillowy surface that wicks away heat and water droplets. Our team discovered through using this product that cotton is also quite hypoallergenic, for any sleepers who want to keep their allergies under control.

After putting it to the test, the primary comfort layer Vaya Comfort Foam, proved to be light and airy yet highly responsive. These 2 inches of foam readily conform under a sleeper to relieve pressure points for full restoration.

The support core of the Vaya Hybrid is 8 inches of pocketed coils on a 2-inch thick foam base. The coils adapt and contour to a sleeper’s body, with firmer coils along the sides that make it easy to slide out of bed in the morning. The packets that encase every coil also ensure that when a person moves or slides out of bed, they won’t disturb their partner’s rest.

The Vaya Hybrid ships free and includes a 100-night sleep trial and a 10-year warranty. We have found from using this product that it truly lives up to its promises of comfort, support, and affordability.

As we trialed their mattresses, we couldn’t help but observe how Amerisleep offers a range of other mattresses, from memory foam beds to hybrids. The brand is committed to making sure at least one of their mattresses can suit a particular sleeper’s needs. However, the Organica is the only latex mattress offered, and that is the primary reason why we choose to highlight it as our top recommendation.

As Amerisleep’s most sustainable mattress, the Organica features materials certified by

Drawing from our experience, the mattress has a balanced medium feel, so most sleepers can enjoy this eco-friendly option.

The cover of the Organica is made with organic cotton and features tufted rosettes. These rosettes are more than aesthetically pleasing. The tufts maintain the Organica’s shape and prevent the layers from shifting out of place.

The Organica’s first layer is made from 1 inch of New Zealand Joma Wool®, which cushions your curves while also acting as a natural flame barrier and temperature regulator. We have found from using this product that it keeps you cool or warm as needed throughout the night.

Next is 3 inches of Talalay latex built to cushion your curves and soothe any pain. Based on our firsthand experience, while Talalay latex provides excellent pressure relief, it won’t cause you to sink deeply into your bed and feel stuck. It keeps your body lifted, making it easier to switch positions and get in and out of bed.

Beneath that is the Organica’s 8-inch coil support unit. Each spring is individually wrapped in durable fabric for motion isolation. This design also prevents the coils from squeaking or breaking easily. An added bonus with the coil unit is the coils are firm on both sides, ensuring you don’t roll off the ends of the bed.

The Amerisleep Organica ships free and is backed by a 100-night sleep trial and a 20-year warranty.

Why Do Mattresses Have Fiberglass?

In the USA, all mattresses must contain some sort of flame retardant to meet federal regulations. It almost goes without saying that the outcome for a sleeper is extremely bleak if a bed is too quick to go up in flames. So these mandated standards have helped save lives.

Chemical flame retardants were originally used in mattresses until people became aware that they’re harmful to humans. So mattresses made in the USA typically include fire barriers with flame-resistant components instead.

Fiberglass is a cheap, chemical-free flame retardant. The material is often referred to as glass wool or glass fibers among the many materials listed on the mattress’s label. In our investigations, we’ve found this is how mattress manufacturers conceal their use of fiberglass.

As our team discovered, fiberglass is commonly found in memory foam mattresses but can be in any type of mattress. If your mattress were to ever catch on fire, the fiberglass would melt without burning and cover the mattress as a flame barrier. The melted fiberglass hinders the spread of the flames.

Mattress brands that have been reported by consumers to use fiberglass include:

Why Might I Want a Mattress Without Fiberglass?

Fiberglass isn’t a toxic material, but it’s also not without potentially harmful side effects. If you come into contact with fiberglass, your skin or eyes might grow irritated. You may also develop breathing or stomach problems.

Now, fiberglass should theoretically be safe enough if it’s kept secure under the mattress cover. This is why many mattress companies tell you not to remove a mattress cover. Yes, even if there’s a zipper for easy removal.

However, customer reviews for inexpensive mattresses with fiberglass have noted that the fiberglass could escape through the cover after extended use. And often they have more to deal with than the realization it’s time to replace their mattress.

Because fiberglass is so small, it can be difficult to keep track of it once it’s loose. This leaves the particles free to spread and cause irritation. And cleaning up fiberglass from a mattress is quite a hassle, and can even require a professional cleaner.

So some shoppers prefer to minimize risk by choosing a mattress without fiberglass, often a latex mattress with natural materials. Common alternatives to fiberglass include:

  • Wool
  • Plant fibers
  • Silica
  • Kevlar
  • Graphite

There are also other benefits to choosing an eco-friendly mattress without fiberglass. For example, choosing a mattress with certified organic materials can reduce your carbon footprint.

Natural mattresses also tend to have lower emissions during the first few days of ownership. These lower emissions are due to their production involving little to no volatile organic compounds (VOCs).

Similarly, people seeking a mattress for allergies often find that a bed with natural materials provides soothing. Their covers may be irritant-free organic cotton, encasing a fiberglass-free flame barrier and a top layer of latex foam.

This is not the case for everyone, as some people are sensitive to animal products and natural fibers, or are allergic to latex. Considering what we learned in our years of experience, we would recommend a well-made memory foam mattress for these sleepers.

How do you know if a natural or organic mattress is living up to its claims? We suggest looking at the mattress’s certifications. Certifications typically show that a third-party organization examined a material’s harvesting and production process. Some organizations also test a material’s emissions.

Notable certifications to keep an eye out for include:

Picking the Right Mattress Firmness

While choosing a new mattress without fiberglass can help you feel secure in your choice, it’s also vital to pick a bed with a firmness that matches your sleeping style. Choosing the wrong mattress for your needs can leave you waking up sore or stiff. Most likely, sleeping on a too-soft or too-firm mattress will leave you with a case of back pain.

Shoppers should consider their sleeping position and body type as they shop. These factors determine how they press down on a mattress.

What if, despite your best efforts, you find yourself with a mattress that’s too soft or too firm? Well, this potential situation is why we always recommend choosing a mattress with a lengthy sleep trial. Most sleepers know within a few months if a mattress isn’t right for their needs.

However, there are ways to change a mattress’s feel. The most common way is to roll a mattress topper across the bed’s surface. For example, a firm mattress topper can revive a mattress that’s softened with age.

Sleeping Positions

The majority of people sleep on their sides, but some prefer their backs or stomachs.

Side sleepers need a mattress with more cushion than other types of sleepers. They usually place greater strain on their shoulders and hips due to the way their body weight is distributed. If the pressure builds up in the shoulders and hips, side sleepers may wake up stiff or in pain. Soft to medium feel mattresses for side sleeping can help minimize pressure and prevent morning aches and pains.

Back sleepers need a stable surface to keep their spine in neutral alignment. Many enjoy a medium-firm mattress for back sleeping, but other back sleepers prefer a medium mattress for softness or a firm bed for support.

Stomach sleepers require a firm surface that minimizes sinkage. If a mattress for stomach sleeping isn’t firm enough, gravity can push the lower abdomen area into the bed. When the stomach and abdomen area dips too far into the mattress, the spine shifts out of its neutral position.

Combination sleepers move between two or three positions in the night, so they need a sleep surface ready to respond to movements and able to support different positions. Mattresses for combination sleeping should offer a buoyant medium feel to adapt to changes.

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.

Body Type/Weight

Your body type and weight can have a significant impact on what the best mattress for you is if you weigh under 130 pounds or over 230 pounds.

Mattresses for petite sleepers should offer a cushioning feel for greater comfort. Smaller sleepers need a mattress quick to conform to their bodies due to the way they press down less than the average person. For example, a medium-soft or soft mattress can provide a petite side sleeper with plenty of comfort.

Conversely, many heavier sleepers enjoy a mattress in the firmer end of their recommended range. Firm feels can soften up under pressure, so a firm mattress often feels more conforming to a plus-size sleeper than it would to a smaller person. Still, many excellent mattresses for heavy people offer a soft and supportive feel.

Types of Mattresses

There are several types of mattresses available in the market, each with unique characteristics and benefits. Some of the most popular mattress types without fiberglass are memory foam, latex, innerspring, hybrid, and air mattresses.

Memory foam mattresses are known for their excellent contouring ability, which provides exceptional support and pressure relief. They are made from polyurethane foam that responds to heat and pressure, molding to the shape of the body. Most memory foam mattresses are ideal for individuals who suffer from chronic pain or prefer a soft and comfortable sleeping surface.

Latex mattresses are made from natural or synthetic latex foam, which is known for its resilience, durability, and hypoallergenic properties. Natural latex mattresses provides firm support and is responsive to movement. In our experience, this makes them an excellent choice for people who want a comfortable and supportive sleeping surface.

Innerspring mattresses are the traditional bed and are still a commonly used type of mattress. They consist of steel coils or springs that provide support to the body. Innerspring mattresses are available in different firmness levels. They can be a great choice for those who prefer a firmer sleeping surface, as a traditional innerspring mattress has a thin layer of padding.

Hybrid mattresses combine the features of memory foam, latex, and innerspring mattresses. They typically consist of a layer of foam or latex on top of a support system made up of springs or coils. Hybrid mattresses provide the best of both worlds, offering the comfort and support of foam or latex with the bounce and responsiveness of springs.

Air mattresses are made from inflatable chambers that can be adjusted to different firmness levels using an electric pump. They are ideal for people who want to customize their sleeping surface and can be a great choice for couples with different firmness preferences.

Now, some types of mattresses are more strongly associated with fiberglass than others, such as memory foam mattresses. However, instead of avoiding most memory foam mattresses, we suggest shoppers also consider a mattress’s price tag. Mattress manufacturers use fiberglass often because it’s inexpensive, so if you see a mattress deal that seems too good to be true, it just might be.

Frequently Asked Questions

Do all mattresses have fiberglass?

No, fiberglass isn’t a universal feature in mattresses. As per our product examinations, natural latex mattresses usually contain another fire retardant, typically wool. This applies to all-latex mattresses and latex hybrids. While some memory foam mattresses and hybrids do contain fiberglass, many do not. Some mattress manufacturers rely on wool, plant fibers, or silica instead for fire protection.

What mattress does not have fiberglass?

If you’re seeking a mattress without fiberglass, the best option is to pick a natural or organic latex mattress. Many latex mattresses contain a layer of certified organic wool in case of fire. Others may have a mix of wool and silica. You can choose an all-latex mattress or go with a latex hybrid for some added bounce.

Why do they put fiberglass in mattresses?

Mattresses made in the U.S. must meet flammability standards in case the mattress ever catches fire. Fiberglass is a common choice as a fire retardant because the material melts in on itself when exposed to high heat. Additionally, fiberglass is inexpensive and non-toxic, although it can cause skin irritation and breathing difficulties.

When it comes to fire barriers inside a mattress, popular alternatives to fiberglass include wool and silica.

Is fiberglass in a mattress bad for you?

Since fiberglass doesn’t release toxic fumes, a mattress can contain fiberglass underneath the cover and still be perfectly safe for sleeping. However, removing the mattress’s cover can release fiberglass particles. These particles can cause:

  • Skin irritation
  • Stomach difficulties
  • Eye irritation
  • Respiratory issues
  • Throat irritation

Cheaply made mattresses may also “sweat” the fiberglass out of the cover as the mattress ages. If your mattress is releasing fiberglass pieces, it’s time to replace it.

Conclusion

When it comes to clean, comfortable sleep, our findings show that mattresses without fiberglass are a solid option for many. Our review of mattress brands and the best mattresses suggest that a latex mattress with a wool fire barrier is often the best way to be sure your mattress contains no fiberglass. Plus, latex mattresses offer other benefits worth considering, as our team’s investigation shows.

However, there are memory foam and hybrid mattresses free of the material, too. It just takes some sleuthing to find one without fiberglass. Researching the mattress’s construction and asking customer service questions about the bed’s fire barrier can help you decide whether a mattress is right for you.
