Do Mattress Toppers Have Fiberglass?

Do mattress toppers contain fiberglass? Yes, but not all. Most mattress toppers include an additional layer of fiberglass as a fire-protectant barrier or mattress protector. Meanwhile, other toppers contain some retardant materials or substances to boost the safety level of their products.

Of note, this layer of protection (fiberglass layers) often settles underneath the fabric. It wards your fiberglass mattress off setting on fire. 

However, this dangerous substance poses several health risks that you can’t undermine.

Where Is The Fiberglass Inside The Mattress?

Lucky you, mattresses don't have any fiberglass on the outside that might irritate your sensitive skin. Their fiberglass fire barrier has an insulating layer underneath the outer shell.

This layer serves as a sort of lining for the bed's inside. With any luck, the fiberglass can extinguish any fire starting on the exterior before it spreads to the highly flammable elements inside the mattress.

While sleeping on a mattress made of fiberglass may sound unsettling, be assured that it is there for your protection. Due to how easily foam may catch fire, this substance prevails for fire-proof items.

Is It Safe For Mattresses To Have Fiberglass?

Yes, if you keep the topper in place.

Fiberglass in mattresses can lead to health effects. Inhaling some types of fiberglass fibers or dust might have a toll on your aspiration. Still, provided the mattress and cover are undamaged, and in place, you shouldn't have to worry about it.

Insulation fiberglass is often made up of shorter, narrower strands, causing skin irritation to the touch, breathing issues, or throat discomfort if breathed.

With that in mind, the mattress cover must always be in place and needs not be removed. There is the potential for the fiberglass in the mattress to become exposed if the cover wears off.

There is no evidence that this substance causes cancer, but touching any of its shards will undoubtedly be unpleasant and possibly irritating.

The fiberglass dust released into the air might create health problems once you remove this cover. Nose, throat, and eye irritation are terrible.

In extreme cases, prolonged exposure to such risks may cause life-threatening conditions, including asthma, bronchitis, or even temporary inability to breathe.

Thus, many customers head for fiberglass-free mattresses.

Protective fiberglass is inexpensive. Low-quality mattress makers are more prone to adopt this tactic than their higher-end counterparts. Fiberglass is commonly used in the inner cover of leading retail mattresses (like memory foam) for less than $600 for a queen size.

Ask The Mattress Companies

Asking the manufacturers directly is a good idea if you find no information on the label or are unsure whether it’s present. 

Any responsible brand would supply all-rounded information for the buyers, such as quality issues, industry standard, your delivery address, return policy, and so on.

Another way, refer to the product description on the brand’s official websites if you can. 

Check The Mattress Label

You should check the label to determine if your mattress or inner cover comprises this flame resistant material.

The law mandates that producers list the inside and outside cover materials on the label. Moreover, the label must specify the amounts of each component.

A mattress with a label contains an exact percentage of glass fiber. Also, the cover removal often causes the fiberglass particles to become airborne. Hence the label should also include "Do not remove the cover."


Mattresses created in the United States may be more high-quality than those made in countries like China. 

Even though only some Chinese mattress manufacturers will use it, it's more probable that an inner mattress cover created overseas will have fiberglass than one made in the USA.
