9 Best Mattresses Without Fiberglass of 2022
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. 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.
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. We’ve rounded up our top recommendations to streamline your mattress shopping experience.
Best Mattresses Without Fiberglass: 30-Second Summary
- The Amerisleep AS3 heads our recommendation list for its balanced medium feel and its affordable comfort as a fiberglass-free memory foam mattress. Plus, its memory foam is also uniquely eco-friendly, as the mattress
Amerisleep’s mattress line-up is a diverse range of beds, from soft to firm and with plenty of options 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.
Now, they also offer mattresses free of fiberglass, including their top mattress seller, the 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.
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. Bio-Pur® is also more 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. As a result, 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. The company is confident that thanks to Bio-Core®, sleepers can get more than a decade of use out of a well-maintained mattress.
The Amerisleep AS3 ships free and comes with a 100-night sleep trial and a 20-year warranty.
- Eco-friendly memory foam responds within seconds to changes and cushions pressure points
- Affinity transition foam features five zones of flexible support
- Durable base foam keeps the mattress from sagging for greater value
Zoma builds its mattresses with a focus on promoting recovery, and as part of that mission, their original Zoma Mattress is now fiberglass-free. Many professional athletes have enjoyed sleeping on the Zoma Mattress, but you don’t have to be a big-name sports star to reap the benefits of the bed. Its restorative features can be unlocked by just about anyone, which is why it’s our runner-up pick for best mattress without fiberglass.
Three foam layers make up the Zoma Mattress, all of which are certified by CertiPUR-US®.
The first foam layer is gel memory foam with special Triangulex™ technology. This technology relies on carefully placed triangles in the shoulders and legs sections to create a more flexible cushion under the body. This boosts the already excellent pressure-relieving capabilities of memory foam, while the mattress stays cool thanks to its gel infusions.
The second foam layer is Reactiv™ foam, a buoyant transition material. Reactiv™ helps the mattress adapt to movements and keeps sleepers from ever feeling trapped in bed.
The Zoma Mattress’s third and final layer is Support+ foam. This base foam was engineered by Zoma to stand strong even after years of sleepers lying down and moving across the mattress, providing unbeatable foam support.
The Zoma Mattress includes free shipping, a 100-night sleep trial, and a 10-year warranty.
- Breathable, ventilated AirCloth cover for cool-to-the-touch surface
- Gel-infused, pressure-relieving memory foam with targeted support
- Buoyant, latex-like transition foam responds to movements
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.
The Zoma Start is an Amazon-exclusive mattress and comes at extremely low prices. Most sizes cost under $500, putting the mattress within reach of most shoppers.
Many memory foam mattresses do rely on fiberglass for their fire barrier, but the Zoma Start does not. This makes it an excellent choice for people who are sensitive to latex or would simply prefer a mattress with memory foam.
Underneath the mattress’s ventilated AirCloth cover, woven to maximize airflow, is an inch of gel memory foam. The added gels transport absorbed body heat away from the sleeper, helping it to escape the mattress entirely. By preventing heat build-up, the Zoma Start helps individuals sleep longer and better.
The next layer is the mattress’s transition foam, the aptly-named Reactiv™ foam. 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.
- Budget-friendly prices and Amazon's convenience
- Cooling gel memory foam for undisturbed sleep
- Buoyant transition foam keeps sleepers from sinking too far
Amerisleep offers eight other mattresses, five memory foam beds and three 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
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®. This layer cushions your curves while also acting as a natural flame barrier and temperature regulator. 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. 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.
At the bottom of the mattress is 1-inch of Dunlop latex. Unlike Talalay latex, Dunlop is durable and firm, making it a great choice for a base foam.
The Amerisleep Organica ships free and is backed by a 100-night sleep trial and a 20-year warranty.
- Has a multitude of third-party certifications
- Features two types of latex
- Coil unit has added edge protection
The Avocado Green is a great eco-friendly option for shoppers in need of a firmer bed. All of the natural ingredients in the Avocado Green also ensure sleepers with sensitivities sleep undisturbed.
The Avocado Green comes in two variations: standard and pillow-top. The pillow-top version is 13 inches thick and has a gentle-firm feel. Meanwhile, the standard version is 11 inches thick and has a medium-firm feel. We’ll be focusing on the standard variety today.
As a sustainable mattress, Avocado avoids adding chemical flame retardants in their mattress. Instead, they feature GOTS organic certified wool in the mattress to meet federal standards. Avocado sources their wool from organic pastures and meets the Responsible Wool Standard. However, they offer the Avocado Vegan Mattress for people who prefer to avoid wool entirely.
The mattress’s button-tufted cover is made from GOTS organic certified cotton. Not only is organic cotton soft to the touch, but it’s long-lasting, moisture resistant, and safe for the environment.
At the top of the mattress is 3 inches of GOLS organic certified Dunlop latex. As a firmer comfort layer, it’s suitable for back sleepers, stomach sleepers, and plus-sized or tall sleepers.
Avocado maximizes support in the Green Mattress by adding up to 1,414 tempered steel coils in it. They’ve arranged the coils into five zones to:
- Support the spine
- Relieve pain
- Alleviate pressure points
Plus, the perimeter of the coils is reinforced to support you from corner to corner.
The Avocado Green comes with a 365-night sleep trial, 25-year warranty, and free shipping and returns.
- Upcycled steel coils arranged in 5 ergonomic zones
- Includes longer-than-average 25-year warranty
- Available in a vegan variety
The Botanical Bliss Organic Latex Mattress by PlushBeds made it into our list for its sheer customizability and countless quality certifications. Not only does it score 4.9 out of 5 stars from over 4,000 reviews, but orthopedic specialists and chiropractors recommend it to back pain sufferers for its superb support.
The Botanical Bliss features a soft cover made from GOTS certified organic cotton. This soft knit maximizes airflow and absorbs moisture so that you sleep cool and comfortably. Since the cotton is organic, it doesn’t contain any harsh irritants that could potentially disrupt your sleep.
Every Botanical Bliss Organic Latex Mattress features a layer of GOTS certified organic wool. Wool is cushiony, durable, and sustainable. It helps regulate your body temperature at night while keeping your mattress clean.
The mattress’s comfort layer is made from Talalay latex. Now, how the latex feels varies based on your firmness choice. In general, though, it’s responsive, breathable, and provides excellent spinal support.
Next are two layers of Dunlop latex. These firm layers promote healthy spinal alignment. Dunlop latex also minimizes sags, soft spots, and overall wear.
Your purchase of a Botanical Bliss Organic Latex Mattress comes with a 100-night sleep trial and a 25-year warranty.

You don’t have to break the bank to get a safe and sustainable mattress free of fiberglass. The Happsy Organic Mattress features sustainable and eco-friendly materials without being unreasonably expensive. Because it’s difficult to find a mattress that’s affordable and natural, we had to highlight the Happsy.
The Happsy Organic Mattress is rated 4.8 out of 5 stars. Customers note how the mattress stays cool and doesn’t cause them to sink in.
The mattress is encased in an organic cotton cover. It draws away heat and moisture while being soft beneath you. Not only that, but Happsy adds cotton filling to the perimeter of the mattress for edge support.
Happsy uses organic latex for their bed’s comfort layer. It featured perforations to maximize airflow while still cushioning your body. The latex is covered in organic wool batting to increase the bed’s breathability and softness.
The Happsy Organic Mattress’s support unit is made from pocketed steel coils. The space between the coils helps air circulate, while the coils themselves isolate motion, support the spine, and keep your body lifted.
The Happsy Organic Mattress is a medium-firm, which works well for stomach and back sleepers. If you’re petite or sleep on your side, you might consider buying the Happsy Organic Mattress Topper, which is made from 2 inches of the same latex in the mattress.
The Happsy comes with a 120-night sleep trial, a 20-year warranty, and free shipping and returns.
- Free of flame retardants, glues, and adhesives
- GOTS organic certified
- Affordable latex hybrid mattress
The EcoTerra Hybrid Latex Mattress made it onto our list for being a handmade bed made from all-natural materials, all while keeping the costs down. Countless customers love the EcoTerra Hybrid Latex Mattress for managing to be natural, luxurious, and affordable.
Unlike many other eco-friendly mattresses, EcoTerra uses a stretchy organic cotton cover rather than a woven one. This makes the surface softer and more breathable while still being durable. Directly beneath the cover is GOTS certified organic wool which enhances cushioning and regulates your temperature.
The mattress features natural latex that is both ECO-INSTITUT and Standard 100 by OEKO-TEX® certified. These certifications mean the foam is free from harsh or synthetic substances.
EcoTerra offers two firmnesses for the latex: medium or medium-firm. Medium works well for side and combo sleepers and couples, while medium-firm suits back and stomach sleepers.
For maximum support, the EcoTerra Hybrid Latex Mattress has upcycled quantum coils. These coils are built to provide edge-to-edge support. Each coil is wrapped in a non-toxic fabric to help them:
- Move independently
- Support your spine
- Increase air circulation
The EcoTerra Hybrid Latex Mattress includes free shipping, a 90-night sleep trial, and a 15-year warranty.
ECOTERRA HYBRID LATEX MATTRESS
- Latex comfort layer comes in either medium or medium-firm
- Wool is thermo-regulating and cushiony
- Hand-crafted in the USA
The Oceano Luxury Hybrid Mattress is Brentwood Home’s best-selling hybrid bed. With nine unique layers and two innerspring units, the Oceano is sure to stand out on your hunt for a mattress. The mattress is 14 inches thick and medium-soft. Its feel is great for side sleepers, petite people, and anyone who prefers an extra-cushioned bed.
The Oceano’s cover is made from Tencel™, a plant-based fabric almost as soft as silk. It’s gentle on your skin, wicks away moisture, and stays cool.
The topmost layer in the Oceano is a layer of GOTS organic certified wool. Many mattresses feature chemical flame retardants. However, Brentwood Home uses wool instead so that you don’t come in contact with any harmful substances.
Beneath the wool is Brentwood Home’s plant-based BioFoam®. This gel memory foam has a CertiPUR-US® seal of approval.
As CertiPUR-US® notes in their FAQs, their certification means a polyurethane foam is free of fiberglass, along with other harmful chemicals such as formaldehyde and retardant chemicals. However, they continue on to say it is still possible for fiberglass to be used in mattress covers surrounding certified foam.
As we noted, the Brentwood Oceano uses wool as a flame retardant, so that isn’t a concern with this option. Still, it’s something to keep in mind as you consider mattresses.
Next comes a 2.5-inch layer of up to 1,722 pocketed micro-coils. The coils are made from recycled steel and are designed for:
- Precise support
- Pressure relief
Under the micro-coils is 1-inch of Air Luxe Foam. Like the BioFoam®, Air Luxe Foam is also CertiPUR-US® certified, but this layer primarily helps with keeping you cool and soothing pain.
The largest layer is the 8-inch ActivEdge™ Quantum® Edge coil unit. This layer contains up to 975 pocketed coils and a reinforced perimeter. The pocketed coils are durable, quiet, and improve your posture at night.
At the very base of the mattress is a durable base foam and cotton cover.
BRENTWOOD HOME OCEANO
- Two unique innerspring layers
- CertiPUR-US® certified memory foam
- Reinforced edge support
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. It 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.
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.
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:
- Plant fibers
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. This is not the case for everyone, as some people are sensitive to animal products or allergic to latex, and 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:
- Global Organic Textile Standard (GOTS)
- Global Organic Latex Standard (GOLS) for latex mattresses
- OEKO-TEX® Standard 100 and their other standards
- CertiPur-US® for memory foam mattresses
- Greenguard GOLD
- MADE SAFE®
- Rainforest Alliance
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.
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 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.
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.
Frequently Asked Questions
Do all mattresses have fiberglass?
No, fiberglass isn’t a universal feature in mattresses. 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.
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.
When it comes to clean, comfortable sleep, mattresses without fiberglass are a solid option for many. 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.
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.
