What Is Fiberglass?

Definition: Fiberglass, scientifically known as glass-reinforced plastic (GRP), is a composite material of fine glass fibers woven into a fabric and set using resin.

Fiberglass beds often contain fiberglass for fire protection. The fiberglass inside serves as a fire retardant layer.

While effective for fire protection, fiberglass poses some health challenges. Consumers should read tags carefully to understand the materials used.

Common Uses:

Fiberglass is ubiquitous in many products and industries—from automotive and aerospace to construction and electronics.

Its high tensile strength, low weight, and weather-resistant properties make it a popular choice for boat hulls, car bodies, roofing, and insulation, among other materials. (Source: U.S. Environmental Protection Agency, "Fiberglass: A Versatile Material").

There are several hazardous flame retardant chemicals that have been used in beds, including:

  • Polybrominated biphenyls (PBBs): PBBs are a group of chemicals used as flame retardants in various products, including mattresses, until they were banned in the United States in 1979.
  • Polybrominated diphenyl ethers (PBDEs): PBDEs are another group of chemicals used as fire retardants in various products, including mattresses.
  • Organophosphate flame retardants (OPFRs): OPFRs are a newer class of fire retardants often used to replace PBBs and PBDEs.
  • Antimony trioxide: Antimony trioxide is a flame retardant used in some mattresses.

Fiberglass in Mattresses:

Using fiberglass in mattresses aims to meet fire-retardant standards set by regulatory bodies. A long-lasting insulating material batting layer is often used beneath the mattress cover as a fire barrier.

Glass fiber plastic (GFRP) is a composite material made of glass fibers embedded in a polymer resin. The glass fibers provide strength and stiffness, while the resin holds the fibers together.

However, this use has sparked debates and concerns regarding health and safety, as the fibers can potentially become airborne if the outer mattress cover is translucent material or the outer cover itself is removed or damaged (Source: Consumer Product Safety Commission, "Standard for the Flammability of Mattresses and Mattress Pads").

Which mattresses contain Fiberglass? These beds have gained traction in the market for several reasons, but the cost is often the most compelling.

These mattresses, like memory foam or latex mattresses, are generally more affordable than their counterparts.

Fiberglass in a mattress can catch fire less easily, but concerns about health issues like lung inflammation make it a controversial choice.

The Pros and the Cons of the Fiberglass Beds

Fiberglass beds offer several pros and cons that consumers should be aware of. On the positive side, the fiberglass inner cover is an effective fire retardant, providing significant resistance to catching fire.

Many mattress makers prefer using fiberglass to meet flammability standards, as it is less expensive than natural flame-retardant materials.

This makes such mattresses safe from open flame fire resistance and more affordable for consumers.

However, the cons are significant. Fiberglass in mattresses can hurt health. When the inner covers are damaged, airborne fiberglass particles can escape and become embedded in upholstery, clothing, and HVAC systems.

This can lead to various health issues, including skin irritation and pulmonary fibrosis.

Furthermore, toddlers are more vulnerable to these harmful materials, making a fiberglass mattress potentially risky.

Mattress Contains Fiberglass: Manufacturers' Labels

Yet, the heat-resistant properties of fiberglass make it a commonly utilized flame retardant agent.

Manufacturers prefer fiberglass over chemicals or heavy metals, which can also lead to health issues. The mattress manufacturer usually specifies how much fiberglass is contained on the tag.

Determining whether your mattress contains glass-reinforcing plastic (GRP) would be best. Unfortunately, not all mattress manufacturers make this information readily apparent. However, there are some key indicators to look for:

Product Labels:

Check the mattress label for words like "glass fiber" or "fiberglass." These labels are usually on a tag sewn into the mattress or packaging.

Material Lists:

If possible, please look over the materials used in the mattress. Many reputable companies will disclose this information on their websites or product manuals.

Fire-Resistant Tags and Fire Retardants:

Mattresses containing fiberglass often have tags indicating they meet fire-resistant standards, which is often an indirect clue about the presence of fiberglass.


According to the Federal Trade Commission, beds that contain glass-reinforced plastic (GRP) must indicate so on their tags.

However, the text can be small and easily overlooked (Source: Federal Trade Commission, "Mattress Labeling Rules").

Despite its functional benefits, consuming fiberglass fragments can cause lung problems and irritate human skin.

Additionally, if the protective layer inside the mattress breaks, the material may spread to other areas, such as upholstered furniture or even an HVAC system.

As more information becomes available, we will likely see a shift in the materials used for flame resistance in mattresses. Before purchasing, it's crucial to understand what each mattress is made of.

How to Handle Fiberglass in a Mattress Safely

Awareness is key. If a company sells mattresses with fibrous glass, it should be transparent about the risks.

Four mattresses recently recalled contained fiberglass that was not properly sealed, leading to heightened consumer exposure.

Tips for Minimizing Risks

Awareness is key when it comes to fiberglass in mattresses. Full transparency about the associated risks is essential if a company sells mattresses that contain this material. Many memory foam mattresses sold with fiberglass act as a fire retardant, but they can present health challenges if not properly managed. Four recently recalled mattresses had fiberglass that was not adequately sealed, leading to increased consumer risks.

Consumers should pay attention to a few key details to use a fiberglass mattress properly.

First, never remove the outer shell or inner cover, as this can release harmful fiberglass shards into the air. If extra comfort is desired, please add a mattress topper that does not contain fiberglass.

Keep the Mattress Cover Intact:

It's crucial to keep the outer cover of any memory foam mattresses sealed. The inner mattress cover often contains fiberglass, designed to act as a fire retardant. If this cover is damaged or unzipped, microscopic fiberglass particles could be released into the air. In case of any damage, opt for fiberglass-free mattress covers as replacements to minimize risk.

Use Additional Protective Layers:

To add another level of safety, use an extra mattress protector or bedding layer. This is a barrier between you and the foam mattresses, whether they contain fiberglass or other chemical flame retardants. Specialized protectors made of natural materials can also reduce exposure to flame-retardant chemicals in the mattress.

If you have a mattress with fiberglass, cleaning it is a delicate process. Use a vacuum with a HEPA filter to suck up any stray particles without releasing them into the air. Traditional vacuums can spread these particles, so a HEPA filter is crucial.

Air Quality:

Maintaining ventilation in the room is necessary, especially when mattresses incorporate fiberglass for its fire-retardant properties. Although air purifiers can help remove small particles, they are not a substitute for a well-ventilated room and proper mattress handling.

Handle with Care:

If the mattress needs to be moved, please be cautious. Dislodging the fiberglass layer can make fiberglass dangerous to your health. Always wear gloves and a protective mask to minimize the risk of inhaling or contacting these particles.

When you dispose of your mattress, consult professionals who can safely handle glass-reinforced plastic (GRP) or other fire-retardant materials. Specialized disposal methods are required to ensure that the fiberglass does not pose an environmental hazard.

Consider Fiberglass-Free Options:

While polyurethane foam is used in memory foam mattresses, it's also possible to find a fiberglass-free mattress that uses alternative fire retardants or natural materials for fire resistance. This can be an ideal solution for those looking to avoid potential health risks while still benefiting from the comfort of a memory foam mattress.

Check the Tag:

Lastly, please always look over the mattress tag. This label will tell you what materials, including fire retardants, are used in your mattress. If it contains fiberglass, you'll know to take the appropriate precautions.

Could you check mattress labels regularly and make sure all covers, especially the fiberglass barrier, are intact? Air purifiers and air conditioners can help minimize the risks but are not substitutes for proper care.

CONCLUSION and Final Thoughts

Choosing the right mattress is more than just a matter of comfort; it's a matter of health and safety.

While fiberglass used in mattresses may be cost-effective, they have many potential health risks, ranging from minor irritations to more serious respiratory issues.

There are safer, fiberglass-free alternatives available that offer not just comfort but also peace of mind.

If you already own a fibrous glass bed, follow safety guidelines rigorously to minimize risks.

Your choice of a mattress shouldn't compromise your well-being; invest in a new mattress with a fiberglass-free option for a healthier, better night's sleep.
