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.

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.
