You’ve probably heard all the horror stories regarding mattresses and fiberglass and that’s why you’re here. Fiberglass has long been used as a flame retardant in mattresses by many mattress companies and although it does help with creating a fire barrier, the health hazard involved far outweighs the pros. But do Casper mattresses have fiberglass? Let’s find out.


Does Casper mattress have fiberglass?

Breathe easy because, no, Casper mattresses do not contain any fiberglass.

The OG memory foam mattress that comes in a box, the Casper mattress has long been – and continues to be – a favorite brand that’s available on the online market today (see our Casper mattress review for more details). Casper is a mattress brand that has paved the way for other brands to make their way through the online mattress space.

Made from mostly all-natural materials, Casper mattresses such as their original foam mattress, still use a mix of synthetic materials but without the harmful chemicals that could get in the way of you getting a good night’s sleep. This is why it’s important to always check for certifications when buying a new mattress. As an example, CertiPUR-US certified foam (like what Casper mattresses and other mattresses like Casper have) are free from any harmful chemicals, VOCs and heavy metals that could be detrimental to both one’s health as well as the environment.

Although made from CertiPUR-US certified memory foam, latex foam (sourced from rubber trees) and organic cotton, Casper mattresses like the Casper Original are not all-organic. If you prefer a completely organic mattress, you can opt for something like the Avocado Green mattress.


Are Casper mattresses toxic?

As mentioned above, Casper mattresses are not toxic and do not contain any hazardous materials. The mattresses are made up of CertiPUR-US certified foam and non-toxic adhesives. All of the materials used in Casper mattresses are safe and certified to meet the highest standards of safety and quality in the United States.

Low-quality mattresses that are not certified are usually the types of mattresses that can cause health effects due to toxicity levels (usually found in the glue used to hold the foam layers together) and fiberglass fire barriers.

Chemicals from the mattress layers can even seep through the mattress cover, turning your bed into a serious health hazard. And you don’t want that.


Why do some mattress brands use fiberglass as a flame retardant?

Simply because it’s cheap. Using fiberglass as a flame retardant, especially in a memory foam mattress, is a cheap yet effective way to help keep a mattress from burning. Other reasons that brands like Nectar use fiberglass are because it’s lightweight and doesn’t have any emissions.

Cost has long been an issue when it comes to mattresses. And some mattress brands have actively been seeking ways to drive down costs or both labor and materials but choosing inferior quality materials and sub-par labor. This includes using fiberglass as a fire barrier.

Yes, fiberglass is effective as a flame retardant but at what cost?


Health risk of fiberglass in mattresses

Although it is mostly considered safe to sleep on a mattress that contains a fiberglass fire barrier, it can also pose a health risk to humans and even pets.

Fiberglass fibers – minute as they may be – can cause tiny cuts and tears to both the skin and the eyes causing anything from rashes to blisters to respiratory problems and even tears in the lungs!

While mattresses have a protective cover aside from the actual mattress cover that holds their fire barrier in, once these fiberglass fibers become airborne, these little glass shards (because let’s face it, that’s what they are) can settle on any surface around your house, making your entire house a health hazard.

FAQs

How do I know if my mattress has fiberglass?

In the US, mattress brands are required to state the components of their mattresses, which can usually be found on the mattress tag. Watch out for words such as ‘glass wool’ and ‘glass fibers’ which are common terms used by mattress companies to mask that the fact that their mattress does contain fiberglass.

Is it safe to sleep on a mattress with fiberglass?

It is generally considered safe to sleep on a mattress with fiberglass, especially if a mattress has passed health and safety standards. But fiberglass fibers can be dangerous when touched or inhaled. Invisible to the naked eye, the fiberglass fibers can cause skin irritation and breathing problems which can then turn into a long term health issue.

Do Casper mattresses off gas?

Casper mattresses are made from materials that are low in volatile organic compounds (VOCs) and do not off-gas. The foams used in Casper mattresses are CertiPUR-US certified. This means that they have been tested and certified by an independent laboratory to US safety standards. A slight new mattress smell can be noticed by some people upon first unboxing the Casper mattress though which is pretty common for memory foam (polyurethane foam). This usually dissipates within 24-48 hours.

Does Casper use flame retardants?

Casper mattresses utilize a knit sock made from silica that sits just under the mattress covers. In the event of a fire, the sock melts on itself and suffocates the oxygen needed for the fire to burn.

Does Casper have formaldehyde?

No. The Casper mattress does not contain any formaldehyde. Casper mattresses are all CertiPUR-US certified. This means they are made without formaldehyde, ozone depleters, mercury, lead, and other toxic chemicals.


Conclusion

Casper mattresses such as as the OG memory foam Casper mattress do not contain any fiberglass flame retardants. This makes the Casper mattress a safe choice when buying a new mattress.

While it has generally been considered safe to sleep on a mattress that contains a fiberglass fire barrier, it would be safer and healthier to avoid it.

Always check mattress tags for any material in the mattress that could pose a health risk. We spend a third of our lives in bed, it is better to be safe than sorry.
