While shopping for my daughter’s first “big girl” bed in 2019 I was shocked to learn about dangerous fiberglass in mattresses. Since then, I have been researching and keeping track of the best fiberglass free mattresses.
There are many mattresses recommended as fiberglass free at the top of search results that actually do contain fiberglass, and that’s very concerning for me.

About fiberglass in Mattresses
Big mattress review websites take what mattress makers say at face value, but I’ve learned that’s not always the best idea. Many mattress brand employees are not well-informed about the fiberglass in their mattresses. Sadly, some mattress maker employees might know about fiberglass but are told to be deceptive on purpose.
What Exactly is Fiberglass?
Fiberglass is a fiber-reinforced plastic made from thin strands of glass that are coated in a layer of resin. The glass is mostly made from silicon dioxide found in silica sand. The resin coating is most often polyester.
Fiberglass can be used as a fabric, or formed into rigid shapes like plastic. It does not rust or corrode and it’s stronger than many metals by a ratio of strength compared to weight. Fiberglass is also very cheap to make so it’s very economical compared to other available options.
Why is Fiberglass Used in Mattresses?
Since 2006 and 2007 mattresses have been held to stricter flammability standards by the Code of Federal Regulations Title 16 Part 1632 and Part 1633. These regulations were put in place because mattress fires had been steadily increasing each year for decades.
Fiberglass does not ignite and burn, it just melts. For this reason, many mattress makers began wrapping the foam inside their mattresses with a fiberglass casing known as a “firesock” in the mattress industry. It was a cheap and effective way to meet the new federal flammability standards set by the government. Many lives have been saved by these regulations according to the Consumer Product Safety Commission.
Is Fiberglass a Danger to Health?
Fiberglass is used in many parts of our everyday lives. Most homes and businesses are weatherized with fiberglass insulation. Patio furniture, fishing poles, boat hulls, and many other things are made with fiberglass. Fiberglass has not been proven to be carcinogenic, and it’s non-toxic.
However, this does not mean that fiberglass is perfectly safe. Fiberglass builders and installers wear respirators and eye protection when working with different kinds of fiberglass. This is because fiberglass presents many unsafe health issues when exposed to it.
Fiberglass in Mattresses is a Skin Irritant
Most people with mattresses that are leaking fiberglass particles first noticed the issue because of skin irritation and itchiness. Severe fiberglass exposure can even lead to skin abrasions and fiberglass dermatitis.
Fiberglass in mattresses is an Eye Irritant
Fiberglass particles are small enough to get captured in the eyes while being nearly impossible to see. Many people that have leaky fiberglass mattresses have said that their eyes were constantly red and itchy until they got rid of their mattress and cleaned up the fiberglass contamination.
Fiberglass in Mattresses is a Respiratory Irritant
Fiberglas particles can irritate the nose, throat, and even the lungs in severe cases. Many people with mattresses leaking fiberglass reported frequent nose bleeds. Studies have shown that inhalation of fiberglass particles can lead to an increase of asthma complications and bronchitis.
Review of the Best Fiberglass Free Mattresses
Best Fiberglass Free Cooling Mattress
Zoma Boost Hybrid Mattress
Zoma Boost Hybrid Mattress Summary:
The Zoma Boost Hybrid is the best hyper-cooling fiberglass free hybrid mattress that money can buy. It features three foam layers and an ultra-cooling polyester and rayon blend cover that keeps the body dry through the night. It also features graphite-infused foam to prevent odor buildup, along with a gel-infused foam layer beneath it for even more temperature-regulated sleep. The Zoma Boost Hybrid coil layer contours to the body while also providing enough support for perfect spinal alignment, plus there’s increased edge support.
Zoma markets the Boost Hybrid as a mattress for active people and athletes that need increased pressure relief and cooling sleep. Waking up in the middle of sleep because you’re hot or have a pressure point breaks healthy REM sleep. Interrupted REM sleep greatly reduces the body’s recovery from exercise and decreases physical performance. The Boost Hybrid page on Zoma’s website has dozens of testimonials by members of professional sports teams that agree with Zoma’s research.
Zoma is a relatively new mattress manufacturer founded by a team with 25+ years in the sleep industry. The main focus of Zoma is performance-enhancing sleep for better health and performance of the mind and body.

How to Choose the Best Fiberglass Free Mattress
Here are some tips for finding fiberglass free mattresses, as well as recognizing fiberglass mattresses. There is also advice for purchasing healthy mattresses in person at brick-and-mortar stores. Plus, there are some tricks for dealing with a fiberglass mattress if you already own one, as well as tips for cleaning up a fiberglass contaminated home.
Recognize Mattress Material Certifications
Mattress makers like to plaster their product pages with certification logos their beds have attained, and they think that’s enough to assure shoppers their mattresses are as safe and healthy as possible! However, some of those mattress certification logos are better than others.
- GOLS and GOTS certifications mean the Latex and Fabrics used are organic.
- OEKO-TEX Standard 100 means the product is Safe and Non-Toxic.
MADE SAFE certifications mean that a products ingredients have been tested to be safe for humans as well as the environment.
However, CertiPUR-US certifications just mean the memory foam is low VOC, but many mattress makers portray their fiberglass mattresses as perfectly safe because they are CertiPUR-US certified.
Ignore Mattress Hype
Influencers will recommend questionable mattresses through social media without knowing the health concerns because they make a living through selling products. Mattress comparison websites will confirm mattresses as containing fiberglass, but then still link out to those manufacturers’ websites. Shady marketing websites only concerned about commissions will tell you that a fiberglass mattress is safe because the fiberglass is “deep” inside the mattress.
Check Mattress Labels
Mattresses must have a Materials and Safety tag attached to them when sold in the United States and many other places. Before buying a mattress in person that has not been thoroughly researched, check the materials section of the tag to be sure it is constructed without fiberglass. If a mattress cover says it’s non-removable then it probably contains fiberglass.
Identify Hidden Fiberglass
Fiberglass is used in many industries and manufactured in different parts of the world, so it may not always be called “fiberglass”. Other terms for it to look for include: glass fiber, spun glass, glass-wool, GRP (glass-reinforced plastic), GFRP (glass-fiber reinforced plastic), GFK (German: Glasfaserverstärkter Kunststoff).
Recognize Healthy Alternatives
Mattresses made without fiberglass will often use Rayon, Polyester, Wool, or Silica to pass flammability tests and meet certification standards. Silica is used in the form of non-woven silica mats beneath the mattress cover, fabrics treated with Hydrated Silica, and in combination with viscose in the production of “inherently flame-resistant” rayon. However, because silica is one of the main ingredients of fiberglass, a mattress maker might try to hide their fiberglass by saying it’s silica instead.
Avoid Cheap Mattresses
The mattresses that most often contain fiberglass are budget options costing less than $1000, especially memory foam mattresses. Although they might seem like a good choice for an affordable mattress, the risks far outweigh the benefit of saving money. This does not mean all mattresses with fiberglass are under a thousand dollars. There are some expensive mattresses that contain fiberglass, and there are some very affordable mattresses that are made without fiberglass.
If you have already purchased a mattress containing fiberglass that isn’t returnable, containment is the best way to mitigate the potential problem until a replacement mattress is obtained. Buy a plastic mattress cover on amazon to put over the mattress to contain any glass fibers that may potentially escape the cover in the future. Get a high mil/gauge rating to ensure the plastic is thick and not easily punctured.
If your fiberglass mattress is already leaking fiberglass, you should take immediate action to contain and clean up the fiberglass before your whole home is contaminated!

John started JSnowCreations as a place to post random tech guides and product reviews. However, while shopping for his daughter’s first “big girl” bed in 2019 he learned about the hidden dangers of fiberglass in mattresses. Since then, John has made it his mission to expose as much hidden fiberglass in mattresses as possible. His ultimate goal is federal regulations that ban fiberglass from being used in mattresses, or at least a law that require it to be listed in the material tags.
