Best Mattresses Without 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. We made sure to include mattresses that can work for a wide variety of sleepers. We’ll also discuss the use of fiberglass more thoroughly in our guide at the bottom.

Saatva Mattress

The Saatva’s coil-on-coil construction provides a classic innerspring feel. It's a good option for combo sleepers, who will want to feel free to switch positions and avoid feeling “stuck” in the mattress. It comes in three firmness levels, so you should be able to find one that suits your needs.

The Saatva Classic is a high-quality mattress that comes in three different firmness levels: Plush Soft, Luxury Firm, and Firm. So most sleepers should be able to find a model that works for their sleeping position. It has a coil-on-coil construction with zoned support, so it’s very durable and supportive. The Saatva is responsive thanks to the bouncy springs, so combination sleepers should be able to easily switch sleeping positions on it. We also love the stellar edge support the Saatva offers. It should allow sleepers to sprawl out and use the full surface of the bed.   

Saatva’s Fiberglass-Free Construction

The Saatva’s cover is made of organic cotton and has an antimicrobial treatment. The company says on its website, “All of Saatva’s mattresses are made from high-quality materials — and we only use safe, nontoxic ingredients for our flame retardant, like natural thistle (plant-based fiber made mainly from wood pulp) and organic New Zealand wool.”

Check out our full Saatva Classic mattress review for more details and if you’re trying to decide on the right firmness level for you, check out our comparison review.

The all-foam Bear Original has a slightly firmer and more supportive feel. Bear creates its beds with athletes and people with active lifestyles in mind by using the material Celliant. Some studies show Celliant can help with recovery by promoting blood flow. The Celliant and gel-infused memory foam in the Bear also help it sleep cool. We think it’s a great value because it uses high-quality materials and comes at an affordable price. At full retail, a queen size is less than $1,000. 

Bear’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.”

The Nolah Natural uses organic and eco-friendly materials, including GOTS (Global Organic Textile Standard) certified organic wool, GOTS certified organic cotton, natural Talalay latex, and recycled steel. These materials give it a soft, plush, and cushioning feel that keeps sleepers lifted on top of the bed. This all makes it a great fit for combination sleepers, back sleepers, side sleepers, and hot sleepers. 

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 percent 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.”

The Avocado Green mattress comes in both a Standard and Pillow Top version. We love the Pillow Top model because it has two inches of latex up top for added comfort. It offers a nice combo of bounce for combination sleepers and sturdy coils for heavier folks. The Avocado Green’s medium-firm feel makes it a great choice for a variety of sleeping positions. The high-quality and eco-friendly materials also make this a really durable bed, so it should last you for a good long while.

Avocado’s Fiberglass-Free Construction

Avocado says on its website, “There are no flame retardants of any kind used in our Avocado Green Mattress or Avocado Latex Mattress. No toxic chemicals, no rayon, no fiberglass fiber ‘fire socks,’ and, of course, no boric acid or other undisclosed chemical treatments used on our organic materials. So how do we meet federal safety standards? We use 100% GOTS organic certified wool, which is naturally flame resistant, in just the right places.”

Hybrid models have become really popular since their blend of materials offer the sought-after combination of support and pressure relief. The Awara Natural Hybrid uses organic cotton, organic wool, natural Dunlop latex, and individually wrapped coils. It contains eco-friendly materials and is completely free of lead, poly foams, synthetic wool, and formaldehydes. We think this bed’s a great match for back sleepers, stomach sleepers, senior sleepers, and combination sleepers. Another reason we love Awara is that for every mattress sold, the company plants ten trees!

Awara’s Fiberglass-Free Construction

An Awara company representative tells Sleepopolis, “All Awara and Awara Premier mattresses are built to meet federal fire safety regulations and do not contain silica or glass fiber in any component of the product.”

Birch is an offshoot of mattress company Helix. Birch is based on providing comfortable and environmentally conscious sleep products. All of the Birch mattress’ materials are sourced from sustainable supply chains, from its organic cotton cover to organic wool to Talalay latex to pocketed coils. The combination of these materials helps it sleep cool and prevent heat from trapping. Overall, it has a classic latex feel that’s springy and supportive. Back sleepers, stomach sleepers, and combination sleepers should find a lot to love in the Birch.

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. “Instead, the Birch mattresses use a combination of organic wool fibers and natural rayon to provide the protection you need without exposure to harmful chemicals. The rayon used in our natural and organic mattresses is a natural fiber that is created from purified cellulose and is harvested primarily from wood pulp,” says Birch’s website.

Big Fig stands for “Bigger Figure,” so you can know with confidence this bed was designed for heavier sleepers weighing over 250 pounds. In fact, Big Fig says it can support up to 1,100 pounds. The mattress has strong edge support and motion isolation, so it would be a nice fit for a lot of couples. There’s also cooling technology built into the Big Fig to promote airflow and help sleepers stay cool.

Big Fig’s Fiberglass-Free Construction

Instead of using fiberglass as a flame retardant, a Big Fig representative tells us they use a blend of natural fibers.

What to Consider When Buying the Best Mattress Without Fiberglass

Fiberglass in mattresses has gained a lot of attention lately due to the hazards it can pose if exposed. 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 can prevent a mattress from bursting into flames if it catches fire and will lead it to slowly burn instead. 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 can 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.

How To Look For Fiberglass In Mattresses

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. You can also check out our guide on fiberglass for more information.

  • Look for organic materials in the mattress. Companies will often use organic materials, like cotton or wool, in the fire barriers of mattresses instead of fiberglass. 
  • Ask the company if they use fiberglass in any form in their materials. 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. If a company is dancing around the question and not being straightforward, trust your instincts and perhaps take your business elsewhere.
  • Check the mattress label. It’s required for every new bed to have a tag that states all the materials used in it. 
  • Avoid purchasing the cheapest option. Since fiberglass is appealing to companies for its low cost, it’s often used in less expensive beds. A good rule of thumb is if a mattress is less than $600 for a queen size, it likely uses fiberglass.

Mattress Types

Although they share the commonality of not containing fiberglass, you may have noticed 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.

Sleeping Position

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

  • Back sleepers: These sleepers are pretty easy to please 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

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. 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.

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.

Our Methodology

Our team of Certified Sleep Science Coaches has reviewed more than 220 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.
