Fiberglass is one of the best flame retardant materials available. It is very effective at preventing fire, and it’s a cheap material that manufacturers can easily get their hands on. These are the main reasons why Zinus uses fiberglass in its mattresses.

Initially, mattress brands used chemicals as fire retardants. They, however, had to discontinue using such when these chemicals were discovered to be harmful to human health. That is when fiberglass became popular.

Other than being affordable, fiberglass is an excellent fire retardant. Suppose a mattress containing fiberglass catches fire, the fiberglass melt and do not catch fire. When they melt, they create a sock around the mattress and prevent the flammable materials inside it from burning. The likes of Zinus memory foam beds are flammable. Without a flame retardant such as fiberglass, these mattresses would catch fire in seconds.

How to Identify a Zinus Fiberglass Mattress?

In Zinus mattresses, you will find fiberglass beneath the mattress’s cover. They surround the foam to protect it from catching fire when exposed to a flame. If you buy a mattress containing fiberglass such as Zinus, it isn’t advisable to look for fiberglass. You may release fiberglass into the air as you do this, and the results can be catastrophic.

For the sake of general knowledge purposes, however, here is where you will find the fiberglass in a Zinus mattress. There is a mattress cover that comes knitted over the bed. Beneath it is the layer of fiberglass. It is directly above the foam. We can’t emphasize enough how important it is that you do not open the cover of your Zinus fiberglass mattress.

Other than opening the Zinus mattress, here are different ways you can identify if the mattress contains fiberglass;

  • If you buy a mattress online, they will indicate how much fiberglass it contains in its description.
  • On your mattress tag, you should see a list of materials used. There you will see if fiberglass is listed or not.
  • A mattress that warns you against removing the cover also indicates that the bed contains fiberglass.
  • Price is also a warning sign that can help you identify if a Zinus mattress has fiberglass. Mattresses that go for relatively low prices tend to incorporate cheap materials such as glass fibers. Rarely will you find this flame retardant in high-end beds.

Research that entails reading articles such as these will also help you know whether a Zinus bed contains fiberglass or not. If these resources don’t answer your question, you can always ask the manufacturer. A reputable manufacturer such as Zinus should openly tell you that their beds contain fiberglass. It is important for you to be able to identify fiberglass on a mattress.

Safety Concerns of Fiberglass in Zinus Mattresses

Without a doubt, fiberglass is one of the best flame retardants found in mattresses. It’s a cheap material, and as a result, it doesn’t affect the overall price of the bed. It isn’t as harmful as the chemicals that were previously used as flame retardants. However, there are a couple of safety issues that you need to know.

If you sleep on a mattress containing fiberglass, it will eventually rise to the surface. When these strands of fiberglass come into contact with your skin, you will experience irritation and itching. Should you inhale or ingest fiberglass, it will irritate your organs. You may sneeze or cough.

There is another drawback of sleeping on a mattress that has fiberglass. Even though it isn’t health-related, the effects can be challenging to remedy. If there is a hole or opening on the mattress cover, fiberglass can pollute the environment. When these strands become airborne, they settle on clothes, furniture, and other items in your bedroom. Getting rid of fiberglass from clothes is very hard. You may even have to seek professional help.

These are the most significant safety concerns of sleeping on a mattress that contains fiberglass. Despite being an excellent fire barrier, we can’t ignore these safety issues. Should you decide that you want a mattress with fiberglass, never remove the cover. You should also inspect the bed frequently. If you spot a hole on the cover, fix it as soon as possible, or replace the mattress right away. Considering that fiberglass is common in low-end beds, the cover could also be of low quality, and you can’t be sure that it will hold up for years. The best thing to do is invest in a mattress protector.

Which Mattress Brands Don’t Use fiberglass? 

There are plenty of mattresses that do not use fiberglass as a flame retardant. Contrary to popular opinion, you don’t have to spend lots of money on fiberglass-free mattresses. You can easily find an affordable bed that uses organic materials such as wool or cotton as the fire retardant instead of fiberglass. These materials work the same way fiberglass does. They slow down the intensity of fires in case the mattress catches a flame. However, unlike fiberglass, you will not get any itches or irritation when you touch wool or cotton. Not unless you are sensitive to these materials as well. In that case, you can invest in a fire retardant-free mattress. You will need a doctor’s prescription for that.

At the same time, you are confident in the bed’s fire protection capabilities.
  • Puffy – Second in line, we have Puffy, a mattress brand known to sell affordable beds. Even though their mattresses are quite cost-friendly, Saatva does not use fiberglass. Instead, they use a rayon and silica fire sock, which effectively prevents the bed from catching fire.
  • Amerisleep – Like puffy, Amerisleep uses silica as a flame retardant. This natural material exists abundantly in nature, and it’s quite sustainable.
