Why do mattresses have fiberglass?


Every mattress made in the USA is required to have a fire retardant under Federal Law. As a result, some mattress manufacturers use fiberglass because it’s an affordable fire barrier solution without chemicals.

In the past, chemical fire retardants were used in mattresses but were harmful to the user’s health. Instead, look for a bed with a natural fire barrier, and it should be Ceri-Pur US certified.

The main reason for including a fire barrier in mattresses is to prevent it from burning as fiberglass and silica melt on the mattress. But, more importantly, this barrier is vital for memory foam mattresses, which are constructed using chemical foaming processes and can cause an inferno without the fire barrier.

Where is the fiberglass located inside the mattress?

Most mattresses with fiberglass have it woven into an inner cover layer. This is because the fire retardant layer of the bed has to surround the foam to protect it from being engulfed in a life-threatening wave of flame. That’s why manufacturers of mattresses with fiberglass layers don’t recommend users remove the top cover to clean it.

How can I tell that a mattress has fiberglass?

If it’s cheap and from China, there’s a high chance that the bed has fiberglass.

Apart from being a health hazard, fiberglass can also cause financial burdens, as getting rid of this material in your home isn’t simple. If the shards get embedded in your clothes, carpet, curtains, and other surfaces, cleaning will be cumbersome and costly. On top of that, you may have to replace most of your things in the house, as fiberglass doesn’t go away quickly.

The most heartbreaking thing is that fiberglass can make you change your residence. If it gets to your clothes, ceiling, clothes, upholstery, window sills, cupboard, and many other places, you may lack any other options than to move into a new house.
