Best Mattress Without Fiberglass

Fiberglass use is common in mattresses for safety reasons. If there were ever a fire in your home, the fiberglass prevents your bed from going up in flames so you can escape.

While fiberglass is important for safety’s sake, it can irritate your body and lungs. And if your mattress were to tear, fiberglass can get all over your bedroom and it’s very difficult to clean.

Why Do Mattresses Contain Fiberglass, Anyway?

You may be wondering, why does my bed contain some weird plastic? What does that have to do with my sleep and comfort? Well, it doesn’t. Fiberglass in mattresses has to do with your safety.

The United States’s federal regulations state that mattresses must contain a flame barrier. Chemical flame retardants are banned in the US because they’re toxic to humans. So, mattress manufacturers turned to fiberglass.

Fiberglass is a cheap fire barrier that’s non-toxic and chemical-free. In the event of a fire, the fiberglass would melt and encase your mattress, preventing it from going up in flames. This gives people enough time to escape and has saved countless lives.

Why Should You Avoid a Mattress With Fiberglass?

There’s a reason people want to avoid a bed with fiberglass.

Technically, fiberglass in mattresses is non-toxic and shouldn’t irritate your body. It stays under the covers where you won’t come in contact with it. Still, the fibers can still escape from under the covers, especially if you unzip the cover or tear it.

Exposure to fiberglass can irritate your skin, eyes, nose, mouth, throat, and stomach. You may develop rashes or itchy skin, red or itchy eyes, a dry nose or mouth, and a sore throat. People who have allergies, asthma, or bronchitis may notice worsened symptoms as well.

Fiberglass isn’t the only flame barrier out there, though. Flame barriers without harmful chemicals include wool, silica, and plant fibers. They’re as safe as fiberglass but won’t aggravate you or your body.

Types of Mattresses Without Fiberglass

There’s no specific mattress type that uses fiberglass. So long as you double-check the mattress’s specifications, any type of bed is fair game. Let’s take a look!

Memory Foam

Memory foam mattresses are cushiony, pressure-relieving types of beds with a “hug-like” feel. The memory foam conforms under your body to soothe aches so you sleep undisturbed all night long.

While memory foam mattresses often contain fiberglass, this isn’t always the case. More and more memory foam manufacturers use different fire barriers in their beds. This way, you don’t wake up feeling irritated or uncomfortable.


Natural latex mattresses are made from the sap of rubber trees. They’re another type of foam bed, only they’re springier and more durable than memory foam or polyurethane foam. They don’t have the same “hug-like” feel as memory foam beds which is great for some people. Plus, latex foam mattresses are cool and supportive.

Natural latex beds are the least likely to contain fiberglass. Latex mattress manufacturers usually don’t add fiberglass to their beds for sustainability’s sake. Instead, you’ll find more natural fire barriers in your latex or latex hybrid bed, such as organic wool or plant fibers.


Innerspring mattresses are a classic type of bed that almost everyone has slept on at some point. These beds are known for their excellent support, bounce, and breathability. They feature pillow tops often made out of cotton, wool, down, or foam.

As a popular type of mattress, innerspring beds come in a wide range of prices. Generally, higher-end models are less likely to contain fiberglass and vice versa. But, this isn’t a universal rule. So always double-check what fire barrier a bed contains before making a purchase.


Hybrid mattresses combine components of both foam and spring mattresses to optimize your support and comfort. They have a coil support system—like innerspring beds—and a foam comfort layer—like memory foam and latex beds. Together, the best hybrid mattresses are springy, supportive, and breathable, yet still cushiony and pressure-relieving.

Unlike most innerspring beds, hybrid mattresses contain pocketed coils. The coils are wrapped in fabric to maximize motion isolation and prevent squeaks and coil breakage. This way, your spine stays in healthy alignment.

The foam layer in hybrid beds must be at least 2 or 3 inches thick to be labeled a hybrid, not an innerspring mattress. The thick layer of cushioning protects the heaviest parts of your body from pressure build-up, soreness, and achiness.

How to Choose a Mattress Firmness

Beyond picking what type of mattress you want, it’s important to choose the right mattress firmness. Mattress firmness affects how cushiony or hard your bed is which is crucial to your comfort at night. Mattress firmness is rated on a scale of 1 to 10, with 1 being the softest and 10 being the firmest.

Choosing a mattress firmness comes down to your sleeping position. How you sleep affects how much cushioning you need to sleep pain-free!

Side Sleepers

Side sleepers need soft to medium mattresses. When side sleeping, the hips and shoulder sink deepest into the mattress. A too-firm surface can let pressure build-up, causing discomfort. Thus, lots of cushioning are needed in a mattress for side sleeping to properly protect their hips and shoulders from pressure build-up and pain.

Still, a soft mattress isn’t to every side sleeper’s taste. Some may prefer a medium-soft, and even a medium bed still offers just enough support to keep the spine aligned.

Some side sleepers may also prefer a bouncy mattress instead of an all-foam. We recommend hybrid mattresses for side sleeping, since a traditional innerspring mattress can feel too firm.

Back Sleepers

When back sleeping, it’s best to use a medium to firm mattress. Back sleepers need lots of spinal support to keep their spine aligned without causing lower back pain. A medium to firm mattress for back sleeping won’t cause you to sink—throwing the spine out of alignment—ensuring you stay comfortable all night long.

Stomach Sleepers

Stomach sleepers need medium-firm to firm mattresses to keep their spines aligned. However, stomach sleeping is arguably one of the worst sleeping positions. It’s hard on your back, can worsen wrinkles and acne, and may inhibit your breathing. Still, it’s difficult to change your primary sleeping position overnight. So, use a medium-firm to firm mattress in the meantime.

Frequently Asked Questions

Does every mattress have fiberglass? 

No, not every mattress contains fiberglass, but it’s very common. Since it’s not always clear whether a mattress has fiberglass or not, you must figure it out on your own. 

Read the fine print of a mattress online or check its label. If you see words such as “glass fibers,” “fibrous plastic,” or even just “fiberglass,” the bed contains fiberglass. 

What type of mattresses doesn’t have fiberglass?

Any type of mattress can be fiberglass-free. It really depends on the company and their standard when looking for a fiberglass-free bed. 

Still, memory foam mattresses commonly contain fiberglass whereas latex mattresses and eco-friendly mattresses are often fiberglass-free. Memory foam beds usually contain man-made materials while latex beds contain mostly natural materials. Still, any type of bed may or may not contain fiberglass. 

How do you know if my mattress has fiberglass?

Mattresses companies rarely advertise their beds as having fiberglass. For shoppers, fiberglass is a no-no due to its irritating properties. So, you’ll have to dig a bit deeper to see what your bed contains.

Check a mattress’s care instructions or label (if you already own the bed) and see if it says “do not remove cover.” This usually means there’s fiberglass under the bed’s cover. It’s important to know that some mattress covers might have zippers and say “do not remove cover.”

Mattresses with third-party certifications are less likely to contain fiberglass. Look for certifications such as Global Organic Textile Standard (GOTS), Global Organic Latex Standard (GOLS), CertiPUR-US®, or OEKO-TEX Standard 100.

Can fiberglass cause lung disease?

No, fiberglass is commonly misconstrued as being deadly or causing long-term health issues, but no evidence supports this. You may notice throat and mouth soreness after being exposed to fiberglass. People with preexisting asthma or bronchitis may have worsened symptoms when exposed to fiberglass as well. However, fiberglass won’t cause lung disease or cancers.

What is the difference between asbestos and fiberglass?

Asbestos and fiberglass are very different materials, despite fiberglass being called the “man-made fiberglass”. Asbestos is a fibrous silicate mineral, while fiberglass is a hard plastic reinforced with glass fibers. Asbestos is a naturally occurring material but fiberglass is man-made.

Both are fibrous and cause adverse side effects when in contact with them. However, asbestos is deadly, while fiberglass only causes mild and temporary symptoms. Chronic asbestos exposure can cause asbestosis, cancers, pleuritis, among other conditions. Fiberglass exposure causes skin, eye, nose, mouth, and throat irritation.


While fiberglass isn’t deadly, it still isn’t an ideal fire barrier in a mattress. Look for an eco-friendly mattress with wool, silica, or plant fiber flame barriers, like our options at Zoma! Beyond just choosing a different fire retardant, compare mattress types and firmnesses to find the best mattress for you!
