The composite material, fiberglass, is made by reinforcing plastic with glass fibers and synthetic chemicals. It is used in many industries to make a wide range of things because it is flexible, cheap, and durable. Several producers include fiberglass in their mattresses.

Including fiberglass in mattresses was originally done to stop a flame from spreading to the bed’s core, which can be made of highly flammable materials.

Types of Fibreglass

The following are the different types of fiberglass:

  • An alkali-resistant glass that is well-known is called AE-glass.
  • Due to its composition of glass fibers, which is practically identical to window glass, A-glass is also chemically resistant to C-glass. It also goes by the name “alkali glass.”
  • Structural glass is another name for S-glass. Because of its mechanical qualities, S-glass is employed.
  • Chemical glass is another name for C-glass. C-glass provides excellent insulation.
  • E-glass, commonly called electrical glass, is a superb insulator.

Benefits of Fibreglass in Mattress

The following are the benefits of fiberglass in a mattress:

  • Low Cost

It is not just efficient, robust, environmentally friendly, and cost-effective compared to most materials. Despite their high price, fiberglass insulation products are excellent insulators. It is occasionally available for far less than other building materials.

It is a logically superior option for insulation in a mattress. Due to the price point and savings, it is the best option.

  • Protection Layer

If a mattress catches fire, the fiberglass it contains creates a layer of protection that keeps the mattress from flaming.

A fiberglass mattress has fiberglass material woven into it; these mattresses are available from Nectar, Ashley, and Zinus. However, the stretch-knit outer cover is safe because it doesn’t contain fiberglass.

  • Variety of Applications

A composite material comprised of plastic and glass fiber reinforcement is called fiberglass. The stretchy material can quickly flatten into a sheet or other shapes for different uses.

Fiberglass is used in many sectors since it is affordable and robust. Everything uses it, including boats, airplanes, bathtubs, and roofs. Fibreglass can also be utilized as a temperature insulator to construct thermal barriers.

Fiberglass use in beds

If the mattress bursts into flames, the fiberglass layer as a fire barrier will melt rather than burn. This is meant to stop the fire from spreading quickly.

Fibreglass is utilized as a fire stopper in mattresses because it is affordable. All-foam mattresses with lower price tags frequently contain fiberglass. Even though other fire-resistant materials besides fiberglass, these mattresses are much more expensive.

Do all mattresses have fiberglass?

While not all mattresses do, a sizable percentage of them do. You must be able to recognize the distinction between fiberglass and fiberglass-free mattresses.

Most mattresses are made with fiberglass, which can irritate the skin and lungs and sometimes have dangerous effects.

Nobody would immediately think of fiberglass while thinking of mattresses. We prefer it if a mattress manufacturer doesn’t imply that our bedding might have hazardous materials. However, producers occasionally add fiberglass to their mattresses. Undoubtedly, many people are becoming increasingly concerned about this. We should especially be more careful when children and seniors are involved.

Can fiberglass hurt you?

Touching fiberglass often doesn’t harm your health over the long term, but contact with it can result in severe irritation, redness, or a rash. Therefore, removing fiberglass from your skin as quickly as possible is critical to prevent it from getting into your eyes, nose, or throat.

How do I know if my mattress has fiberglass?

If the label on your mattress reads “XX% glass fibre,” fiberglass is present. As removing the cover causes the fiberglass fragments to fly into the air, your label should also include, “Do not remove the cover.”

What is the purpose of the fiberglass in the bed?

Since it is a low-cost flame retardant, fiberglass is occasionally used in mattresses. It may surprise you, but that excellent, comfortable mattress in your bedroom is quite flammable, especially if it is made of memory foam.


Although fiberglass is added as a safety barrier to stop the fire from spreading, we must conclude that it is not a healthy substitute for chemical sprays.

The likelihood that you may eventually breathe in fibers that cause allergens similar to those brought on by chemicals is equal, and fiberglass is much more difficult to remove.

This risk is especially important to consider if you have elderly family members, young children, newborns, or anyone with breathing or skin conditions in your household.
