There has been a lot of press around the fact that Zinus mattresses contain fiberglass. Is this true?
Perhaps this isn’t something that’s crossed your mind, but even though inhaling fiberglass can be very dangerous, many mattress companies use this as a fire retardant on their products.
That means that potentially thousands of people could be breathing in fiberglass every night. So do the Zinus mattresses use fiberglass in their construction? Keep reading to find out.
Is There Fiberglass In Zinus Mattresses?
Yes, there is some fiberglass used in the construction of Zinus mattresses. Specifically in the fire retardant “fire sock”, just below the cover.
When asked about it though, the company will say that they use “silicon fiber,” which is just another name for the same material.
Many of the one-star reviews for Zinus mattresses on Amazon show images of this “sillicon fiber” breaking down after some time.

Why Is Fiberglass Used In Mattress Construction?
According to federal law, a fire retardant must be used in the construction of every mattress that is offered for sale in the United States.
Within mattresses, fiberglass is utilized as a low-cost alternative to the usage of potentially hazardous chemicals. This is used to provide a barrier against the spread of fire.
While we’re not saying that all mattress companies use fiberglass in their products, what is true is that this is a budget option for fire retardant, making it more common in budget mattresses.
There was a period when chemical fire retardants were occasionally employed in mattresses. However, as it was revealed that some of these fire retardants were detrimental to human health, their use was phased out.
If for any reason your mattress caught fire, the fiberglass is designed to melt into itself without catching fire, creating a protective layer or “sock” surrounding the mattress.
Because memory foam mattresses are produced utilizing chemical foaming techniques, they would quickly become raging flames if they lacked any fire barriers. Because of this, having a fire barrier is quite necessary and you should always have some form of fire protection on your mattress.
Where In The Mattress Is The Fiberglass?
It’s necessary for the foam in a mattress to be encircled by a fire-resistant layer to prevent the foam from being consumed by a wave of fire occur.
If you buy a mattress that has fiberglass in it, you’ll find that the fiberglass is woven into the cover of the mattress’s internal layer. This is where it is found inside of a Zinus mattress as well.
The stretch knit cover of the Zinus mattress is the surface that you lie on. Below that, there is a layer of internal fabric that is thinner and that encases the mattress foams. Fiberglass is woven into the relatively thin layer that covers and protects the foam inside.
Because the stretch knit cover on the exterior does not include any fiberglass, you will not be sleeping directly on it. Remember though, you mustn’t remove any cover from a mattress that has fiberglass integrated into the inside cover, as this is one way to spread fiberglass all over your room.
Is It Safe To Sleep On A Fiberglass Mattress?
While fiberglass can be very dangerous if breathed in, that doesn’t mean that all mattresses containing this product are dangerous as well. Because of this, the answer is both yes and no.
It’s Yes If…
Used as a fire retardant, as it’s excellent at this job. It’s an alternative that is friendly to the company’s bottom line and allows the company to make cheap, fire-resistant mattresses without having to use harmful chemicals in the fire barriers.
It’s No If…
If the fiberglass somehow gets out of the mattress, you will have very fine strands of it all over your bed, your bedroom, and your house.
This is because fiberglass is a very fibrous material. Itching, discomfort, and sometimes even minor wounds might result from this. Because the fibers are so minute, it will be quite difficult to completely clean up the mess once they have been released.
How To Sleep Safely
If you choose to purchase a mattress that contains fiberglass, you can be confident that it will serve as an effective fire barrier for your home. However, you need to be very careful that you never take off the mattress’s cover, as this is how fiberglass can spread around your home.
Because fiberglass can sometimes be found in less expensive mattresses, you should give some thought to how long-lasting the cover is. Even if you make every effort, you could still end up with fiberglass contamination if the cover tears or otherwise falls apart.
Putting a mattress protector on top of the mattress is the most effective measure you can do to protect yourself from this problem.
How Can I Tell If My Mattress Contains Fiberglass?
Have you bought a mattress second-hand and are now having a bit of a panic about whether it’s made of fiberglass or not? Unfortunately, it can be pretty hard to tell whether or not this material has been used. One good indicator that it does have fiberglass though is if it has a non-removable cover.
Another tell-tale sign is if the mattress is from a budget brand, or is a cheaper/the cheapest option made by any mattress brand.
When the price of your mattress becomes closer to one thousand dollars, that’s when you can expect them to switch to a different material for their fire barrier. You’ll also find that many of the cheaper mattresses sold on Amazon have coverings that are not removable.
This, paired with their price range, is a dead giveaway that there is fiberglass within as the fire barrier.
What Mattresses Don’t Contain Fiberglass?
There are several mattresses out there that don’t use fiberglass or harmful chemicals in their fire barriers. Even while they typically come at a higher price point, you may still find an excellent mattress without fiberglass for around a thousand dollars.
