Do Zinus mattresses contain fiberglass? Yes is the clear-cut response. Many Zinus mattresses include fiberglass. The substance in issue is used as a fire retardant by several mattress manufacturers. It is referred to as “glass fiber” by the Zinus Mattress business, which means it contains fiberglass particles.
If you read any Zinus mattress reviews on Amazon, the conclusions may be questionable and inaccurate. You may note, however, that some reviews with one star are replete with criticism and images of the glass fibers visible on the Zinus mattress tag. Fiberglass is another subject that is often discussed.
Upon unzipping the inside cover of a Zinus mattress, fiberglass that serves as a fire retardant is revealed. Not just one of their mattresses is under question. The majority of Zinus mattresses, including memory foam mattresses, include fiberglass within. Additionally, when you take the mattress cover off your Zinus mattress, you run the risk of dispersing fiberglass particles into the air, which might endanger your health and seriously injure your home.
However, many are unsure of the severity of the problem and whether purchasing a Zinus mattress is indeed safe.
Benefits of Fiberglass in Mattresses
A mattress with fiberglass inserted as a protective layer inside the cover often has just one function: to prevent the mattress from catching fire. Fiberglass produces a fire retardant protective layer to fend off any fire dangers, and is often used in memory foam brands such as the Zinus mattress.
Why does a Zinus Mattress utilize fiberglass as a flame retardant? mostly because it is inexpensive and somewhat secure.
A synthetic substance made of poly-foam, which is created from petroleum, is memory foam. You may already be aware that petroleum is a very flammable substance that may quickly set fire to your mattress and then spread to the rest of your home.
Considering this, the fiberglass fire retardant nestled into the outer layers of the mattress cover would melt if your room caught fire, preventing the mattress from catching fire.
In memory foam mattresses, glass fibers serve primarily this purpose. As a fire retardant, fiberglass is a safer option than organic materials, according to certain manufacturers, including Zinus mattresses, who openly confess using it in their mattresses.
It is also less expensive than organic materials, which are utilized by other mattress firms.
However, let’s say your mattress has a rip or the mattress tag is missing.
When that happens, you endanger both your home and your health, therefore at the absolute least you should add a detachable outside cover to safeguard both.
Some customers decide to choose a mattress devoid of memory foam in order to obtain a bed free of fiberglass more quickly.
Where is Fiberglass Within the Mattress?
Memory foam must be encased in a fire-resistant inner cover layer of a mattress. The fiberglass within, together with an outside cover to keep the fiberglass confined, prevents the bed from enveloping in a wave of flame.
If you purchase a Zinus mattress, the inside cover layer will have fiberglass woven into it. In a Zinus mattress, you’ll discover it here.
The top layer of a Zinus mattress is a stretch-knit cover that you lie on. Below that is a thinner layer of fabric that makes the mattress flame-resistant. The stretch-knit cover on the outside of the mattress doesn’t have any fiberglass, so you won’t be lying on the fibers. Inside, the fiberglass is braided into a thin layer that goes all the way around the cushion.
To prevent exposure to the fiberglass layer, you must not remove any portion of the cover from a mattress that has fiberglass in the internal cover.
Why Does Zinus Use Fiberglass in Their Mattresses?
There should be some explanation as to why fiberglass is utilized in Zinus beds in the first place before we talk about the safety issues with fiberglass in the Zinus mattresses.
Federal law mandates that all mattresses made and sold in the US must be fire resistant. One of the best flame-retardant materials available is fiberglass. The substance melts when heated, encasing the combustible inside of a mattress.
Fiberglass is a cheap material that manufacturers can readily acquire, and it can stop a fire from spreading. These are the main explanations for why fiberglass is used in Zinus mattresses.
Fiberglass isn’t the only material that can match those requirements, despite being a popular choice. For those who choose to stay away from fiberglass contamination, there are fiberglass-free mattress solutions available, such as organic latex mattresses.
Dangers of Owning a Mattress with Fiberglass
Fiberglass in your house comes with a number of risks. These microscopic glass strands may easily stick to your skin, clothing, and hair, making it difficult to get rid of them. More importantly, they may result in certain health issues.

Additionally, inhaling fiberglass could hurt your nose or throat. Even severe bronchitis has been reported in certain instances of fiberglass inhalation. Children and others who suffer from allergies may be at greater danger from this.

A person who has been exposed to fiberglass over a lengthy period of time may get bronchitis, cough for days, and even leave the home to enable the fiberglass to leave the environment.
If a small area of your home is exposed to fiberglass particles too much, it could get into your ventilation system, air conditioner or heater and cause more damage while making cleanup more difficult.
In the past, individuals have been compelled to leave their houses and hire professionals to clean up the fiberglass pollution as a consequence of fiberglass contamination ventilation systems. This approach may be up to 10 times more expensive than purchasing a high-quality latex or organic mattress.
Fiberglass is not currently thought to be cancer-causing or to provide a long-term danger. On the other hand, scientists keep looking into it and learn more about its potential effects, igniting new debate. Concerns about studies associating fiberglass and the fatal malignancy mesothelioma are still being discussed.
Is It Safe to Use a Fiberglass Mattress?
Sadly, the answer is “it depends.” A great fire retardant is fiberglass. With this low-cost method, mattress manufacturers may build affordable, fire-resistant mattresses without using hazardous chemical flame retardants in their fire barriers.
You will have tiny strands of fiberglass all over your bed, bedroom, and home, however, if the fiberglass escapes from the mattress. Discomfort, irritation, and even small wounds may arise from this. The fiberglass will be nearly impossible to remove from the mattress because of how thin the strands are.
This suggests that you can be guaranteed of a reliable fire barrier if you get a mattress made of fiberglass. Nevertheless, always keep in mind to leave the mattress cover on.
Furthermore, you should think about the cover’s longevity since fiberglass is often found in cheaper mattresses. Best efforts aside, fiberglass contamination will result if the cover rips or collapses.
The simplest solution to solve this issue is to cover the mattress with a mattress protector, which you should do anyway to preserve the mattress’s quality.
How Do You Determine if the Zinus Mattress has Fiberglass?
Under the mattress cover of Zinus mattresses, fiberglass may be detected. They enclose the foam in order to prevent fires, if it comes into touch with a flame; the foam melts under the heat to form a makeshift encasement.
When buying a mattress containing fiberglass, like the Zinus, it is not advised to deliberately search for it. You could discharge fiberglass into the air by opening the lid, which might be terrible for the nearby neighborhood.
Here are some more techniques to determine if a mattress contains fiberglass apart from opening the cover that you just purchased:
- The amount of fiberglass in the mattress should be disclosed in the description if you purchase it online.
- The labeling on your mattress should provide a list of the materials utilized. Although the words “glass fiber” or “glass-reinforced plastic” might be used instead, you can tell if fiberglass is mentioned on the label or not.
- It also means that the bed probably contains fiberglass if the mattress warns you against removing the cover.
- Another warning sign that may reveal if a Zinus mattress includes fiberglass is its price. Mattresses with moderate to low price tags usually include inexpensive materials, such glass fibers. It is unusual to see this flame retardant in expensive, plush mattresses.
You can determine if fiberglass is present in a Zinus bed by reading information like this. If none of these websites answer your question, you may always get in touch with the business.
A reputable producer, like Zinus, should be transparent about the use of fiberglass in their beds. Look elsewhere if customer care attempts to sidestep the query without providing an answer.
It is crucial to know if a mattress contains fiberglass before purchasing, particularly if you are sensitive to it.
