Does Brooklyn Bedding Have Fiberglass?

Founded in 1995 by the Merwin brothers, Brooklyn Bedding has grown to become a leading mattress brand here in the US. All Brooklyn Bedding mattresses are manufactured at their factory in Arizona. They have a wide range of mattresses ranging from hybrids to organic models, which are all moderately priced. Has a particular Brooklyn Bedding mattress caught your attention? A good rule of thumb when mattress shopping these days is to rule out if it has fiberglass. That’s why we have taken the initiative to research and review whether Brooklyn Bedding mattresses contain fiberglass.

Does Brooklyn Bedding Have Fiberglass?

When you visit their official website, Brooklyn Bedding clearly states that they use a high-quality flame-retardant sock that is a fabric blend of cotton, polyester, rayon, and non-woven silica. Therefore, according to Brooklyn Bedding, their mattresses are fiberglass-free.

If you are a fan of our reviews, you can testify that Sleep Aim’s mattress testers always engage in thorough research. Therefore, we were not satisfied with Brooklyn Bedding’s claims and we headed to Reddit to find out what other people think about these mattresses and fiberglass.

To our surprise, we came across a recent Brooklyn Bedding post on Reddit, where a certain user mentioned that they started experiencing eye and skin irritation after buying this mattress. These are two key signs of fiberglass exposure.

Beneath the above post, there were lots of counter-arguments, where other users denied that Brooklyn Bedding mattresses do not have fiberglass.

However, out of all these arguments about Brooklyn Bedding mattresses having fiberglass, there was one comment that caught our attention. A certain Reddit user going by the name mk734 mentioned that he bought three Brooklyn Bedding mattresses and in two of them, fibers were visible when you pointed a flashlight towards the mattress. In the other Brooklyn Bedding mattress, there weren’t any fiber particles visible.

According to our professional analysis, we have concluded that Brooklyn Bedding mattresses are fiberglass-free. We can also confirm that they do use a fire sock made out of non-woven silica, rayon, polyester, and cotton.

From the above reviews on Reddit, it’s pretty clear that most people easily confuse silica for fiberglass.

Fiberglass is made out of around 65% silica and other ingredients. On the other hand, silica is made mainly out of silica sand. As a result, they are completely different materials that undergo varying manufacturing processes. One of the few similarities between these two is that both can be used as flame retardants.

Like fiberglass, silica is a mild abrasive. Therefore, when it rubs against your skin you may experience some irritation. Also, when it gets into your eyes, being a foreign element, you will feel some irritation. Also, non-woven silica will reflect light from a flashlight. This explains why some people may confuse the silica in Brooklyn Bedding mattresses for fiberglass.

Therefore, the bottom line is that Brooklyn Bedding mattresses do not have fiberglass. However, beneath the cover, you will find silica, cotton, rayon, and polyester.

Is Fiberglass and Silica the Same?

In the past, several mattress brands have been found guilty of using misleading phrases such as glass fiber or glass wool to divert the attention of shoppers from fiberglass. However, we can confirm that silica is not another name for fiberglass. As explained earlier, these are two completely different things. Therefore, when you see silica on a Brooklyn Bedding Mattress, you need not panic thinking that it’s fiberglass.

And the good news is that Helix also doesn’t use fiberglass in their mattresses. Initially, Helix mattresses used to have fiberglass but they learned the dangers of this material and stopped using it.

What are the Dangers of Fiberglass in Mattresses?

Many mattress shoppers are head over heels looking for fiberglass-free models. But do they understand the dangers of fiberglass in mattresses?

Fiberglass is a pretty useful material. When woven over a mattress, it prevents it from catching fire and being engulfed in flames. When used in a mattress, fiberglass is safe as long as it doesn’t escape through the cover. Because mattress covers are not made out of steel, fiberglass particles will eventually escape.

When these particles escape, they can irritate your skin, throat, and eyes. Fiberglass particles can also worsen symptoms of asthma and other respiratory conditions.

If fiberglass in a mattress, escapes into the air, it can contaminate your clothes and furniture, thus leading to expensive cleanups. Unlike other contaminants, fiberglass shards don’t come off clothes and furniture easily. To clean these particles, you may have to seek the services of a licensed cleaning company.

Do All Mattresses Have Fiberglass?

Not really. Brooklyn Bedding is a great example of a mattress without fiberglass. There are many mattress brands out there that do not have fiberglass. With a little bit of research, you can identify these brands and never have to worry about fiberglass contamination.

At the same, time, most cheap memory foam mattresses you come across may have fiberglass. So, you have to be careful when shopping if you don’t want a fiberglass mattress.


Brooklyn Bedding is very clear that their mattresses do not contain fiberglass. From our research, we found out that these claims are true. And the people who are alleging Brooklyn Bedding mattresses contain fiberglass, are confusing those particles with silica which has a slight resemblance.
