Do Zinus Mattresses Have Fiberglass?

Is fiberglass used in Zinus mattresses? The simple answer is yes. Fiberglass is present in many Zinus mattresses. Many mattress brands use the material in question as a fire retardant. The Zinus Mattress company defines it as “glass fiber,” the same as fiberglass particles.

The results can be dubious and unreliable if you read any Amazon reviews of Zinus mattresses. However, you may notice some one-star ratings are filled with remarks and photographs of the Zinus mattress tag showing glass fibers. Zinus memory foam mattress fiberglass is also a prevalent topic.

When you unzip the inner cover of a Zinus mattress, you’ll discover fiberglass that acts as a fire retardant. We’re not just talking about one of their mattresses. Most of Zinus’ mattresses include fiberglass inside, including memory foam mattresses. In addition, when you remove the mattress cover from your Zinus mattress, you may spread fiberglass particles into the air, which can harm your health and cause significant damage to your property.

However, many wonder how serious the issue is and if you can genuinely buy a Zinus mattress and enjoy it safely.

What is a Zinus Mattress?

A Zinus mattress is a popular and affordable option in the mattress industry, mainly known for its use of memory foam. Zinus offers a range of mattresses designed to cater to various sleep preferences, from firm to plush, and includes hybrid models that combine foam and innerspring coils for added support. These mattresses are typically compressed and shipped in a box, making them easy to transport and set up.

One of the distinguishing features of Zinus mattresses is the use of fiberglass as a fire retardant. While this material effectively meets safety regulations, it has raised concerns among some consumers due to potential health risks if the fiberglass becomes exposed.

Zinus mattresses are widely available online and through major retailers, offering a budget-friendly solution for those seeking a new mattress. However, before making a purchase, it’s essential to consider the materials used and their potential impact on your health and comfort.

What Materials Are Used in Zinus Mattresses?

Zinus mattresses are constructed using various materials designed to provide comfort, support, and durability at an affordable price. The core construction typically consists of multiple foam layers, each serving a specific function to enhance the overall sleep experience.

Memory Foam: The top layer of many Zinus mattresses is made of memory foam, a material known for conforming to the body’s shape. This layer offers pressure relief by evenly distributing weight and alleviating stress on crucial areas like the shoulders, hips, and lower back. 

Some Zinus models incorporate gel-infused memory foam, which helps to dissipate heat and maintain a cooler sleeping surface.

Comfort Foam: You’ll often find a layer of comfort foam beneath the memory foam. This layer provides additional cushioning and enhances the mattress’s overall plushness. It also helps transition the body’s weight to the more supportive layers below, ensuring a balanced feel that isn’t too soft or firm.

High-Density Support Foam: The base layer of Zinus mattresses is usually made of high-density support foam. This layer serves as the foundation of the mattress, providing structural integrity and deep support. It helps maintain the mattress’s shape over time and ensures that the sleeper’s body remains properly aligned.

Innerspring Coils (in Hybrid Models): In some Zinus hybrid models, the mattress construction includes a layer of innerspring coils sandwiched between foam layers. These coils add a traditional bounce to the mattress and enhance breathability by allowing better airflow through the mattress. 

Fiberglass Fire Retardant Layer: To meet safety standards, Zinus mattresses include a layer of fiberglass woven into the mattress cover’s inner layer. This fiberglass acts as a fire retardant, helping to prevent the spread of flames in the event of a fire. 

While effective for safety, this material has sparked concern due to the potential health risks if it becomes exposed.

Knitted Fabric Cover: The outermost layer of Zinus mattresses is typically a knitted fabric cover. This soft, breathable fabric enhances the mattress’s overall comfort and helps protect the inner layers. It’s important to note that Zinus advises against removing this cover to avoid the risk of exposing the fiberglass layer beneath.

What is Fiberglass?

Fiberglass is a composite material made from fine glass fibers. It is widely used across various industries due to its strength, durability, and resistance to heat. 

In mattresses, fiberglass is often used as a fire retardant, helping to meet safety regulations without the use of harmful chemicals. When incorporated into a mattress, fiberglass serves as a protective barrier that can slow down or prevent the spread of flames in the event of a fire.

Fiberglass is favored in mattress manufacturing because it is cost-effective and non-toxic when contained properly. However, if the fiberglass layer is damaged or exposed, it can pose health risks. 

The tiny glass fibers can become airborne and, if inhaled or touched, may cause irritation to the skin, eyes, and respiratory system.

What does fiberglass look like in a mattress?

Fiberglass in a mattress typically appears as a thin, cloth-like layer that resembles a fine mesh. It has a white or translucent appearance and comprises tiny, thread-like glass fibers woven together. 

This layer is usually embedded beneath the mattress’s outer fabric cover, so it isn’t visible unless the cover is removed or damaged.

When you look at fiberglass, it might resemble a delicate, woven fabric or fine netting. The fibers are extremely thin, almost hair-like, and due to their glass composition, they can appear slightly shiny under light. 

This mesh-like layer is spread evenly across the mattress to create a uniform barrier that helps prevent the spread of flames in case of a fire.

Because fiberglass is made of such fine fibers, it’s important to avoid disturbing it. If the mattress cover is removed or torn, these tiny glass fibers can become airborne and, due to their small size, are challenging to see individually. 

However, if exposed, they may appear as a dust-like substance or fine threads that irritate the skin and respiratory system.

Benefits of Fiberglass in Mattresses

A mattress with fiberglass inside the cover as a protective layer generally serves only one purpose: to keep the mattress from catching fire. Commonly seen in memory foam mattresses like the Zinus mattress, fiberglass creates a fire retardant protective layer to prevent potential fire threats.

Why use fiberglass as a flame retardant in a Zinus Mattress? Mainly because it is low cost and relatively safe.

Memory foam is a synthetic material formed of poly-foam, which is manufactured of petroleum. Petroleum, as you may know, is a highly flammable material that can easily cause your mattress to catch fire and spread the fire throughout your entire house.

Keeping this in mind, if your room were to catch fire, the fiberglass fire retardant tucked into the outside layer of the mattress cover would melt, saving the mattress from catching fire.

That is the primary function of glass fibers in memory foam mattresses. Some manufacturers, such as Zinus mattresses, which openly admit using fiberglass in their mattresses, stated that the fiberglass is tucked away inside the inner mattress cover of the mattress, making it a safer choice as a fire retardant and at a low cost in comparison to organic materials used by other mattress brands.

Nonetheless, suppose your mattress has a hole in it or the mattress tag is missing. In that case, you are putting your house and health in danger, and a removable outer cover should be added at the very least to protect yourself and your home. Some shoppers opt to pick a mattress without memory foam to find a bed without fiberglass more easily.

Where is Fiberglass Within the Mattress?

A mattress’s fire retardant inner cover layer must encircle the memory foam. This keeps the bed from engulfing in a wave of flame thanks to the fiberglass inside, with an outer cover to keep the fiberglass trapped.

If you buy a Zinus mattress with fiberglass, it will be woven into the internal cover layer. This is where you’ll find it in a Zinus mattress.

Zinus has a stretch knit mattress cover top layer that you lie on, followed by a thinner interior fabric layer that encases the mattress flame retardant. The outside stretch knit mattress cover has no fiberglass, so you will not be lying directly on the fiberglass particles. The fiberglass inside is braided into a thin layer that surrounds the cushion.

You mustn’t remove any part of the cover from a mattress with fiberglass in the interior cover to avoid exposure to the fiberglass layer.

Why Does Zinus Use Fiberglass in Their Mattresses?

Before we discuss the safety problems with fiberglass in Zinus mattresses, there should be some clarification as to why fiberglass is used in Zinus beds in the first place.

All mattresses manufactured and sold in the United States are required by federal law to be fire retardant.  Fiberglass is one of the most effective flame retardant materials on the market. When the material is exposed to heat, it melts to encase a mattress’s flammable insides.

So fiberglass can prevent a fire from spreading and is a low-cost substance that manufacturers can easily access. These are the primary reasons why Zinus mattresses incorporate fiberglass in their mattresses.

However, while fiberglass is a popular material to meet those specifications, it’s not the only one that can do so. There are fiberglass-free mattress options for people who like to avoid fiberglass contamination, such as an organic latex mattress.

Dangers of Owning a Mattress with Fiberglass

There are various dangers associated with having fiberglass in your home. These tiny glass fibers can readily attach to your clothes, body, and hair, making them tough to remove. More significantly, they can create some health problems.

There is currently no evidence that long-term exposure to fiberglass causes permanent health issues. However, being exposed to fiberglass can irritate your skin and cause your eyes to become inflamed, red, and painful.

Furthermore, breathing fiberglass may cause discomfort to your throat or nose. Inhaling fiberglass has even resulted in certain cases of severe bronchitisVerified Source National Library of Medicine (NIH)World’s largest medical library, making biomedical data and information more accessible.View source. This can be particularly risky for allergy sufferers and youngsters.

Fiberglass exposure and inhalation can result in acute problems that can linger for days. This can result in swelling and itching, as well as skin redness and irritation of the nose, mouth, and eyes. In addition to the bronchitis indicated above, someone exposed to fiberglass for an extended period may cough for days and even leave the house to allow the fiberglass to escape the environment.

If a small area in your house is overly exposed to fiberglass particles, it might infiltrate your ventilation system, heater, or air conditioner, causing even more harm and increasing the difficulty of cleaning the fiberglass up.

As a result of fiberglass contamination in the ventilation system, people in the past have been forced to leave their homes and engage specialists to clean up the fiberglass pollution. This method can cost up to ten times as much as paying for a good-quality latex or organic mattress.

At this time, fiberglass is not considered carcinogenic or associated with chronic risk. Scientists, on the other hand, continue to investigate it and discover more about its possible consequences, sparking fresh discussion. There is an ongoing debate about researchVerified Source National Library of Medicine (NIH)World’s largest medical library, making biomedical data and information more accessible.View source linking fiberglass and mesothelioma, a deadly tumor.

Is It Safe to Use a Fiberglass Mattress?

The answer is, unfortunately, “it depends.” Fiberglass is an excellent fire retardant. It’s a low-cost approach that allows producers to make inexpensive, fire-resistant mattresses without employing harmful chemical flame retardantsVerified Source National Library of Medicine (NIH)World’s largest medical library, making biomedical data and information more accessible.View source in their fire barriers.

However, if the fiberglass escapes from the mattress, you’ll have fine strands all over your bed, bedroom, and house. This can result in discomfort, inflammation, and even minor wounds. Because the strands are so thin, cleaning the fiberglass off the mattress will be practically difficult.

This implies that if you buy a mattress with fiberglass, you may be sure of a solid fire barrier. Still, you must remember never to remove the mattress cover.

Furthermore, because fiberglass is commonly present in lower-cost mattresses, you should consider the cover’s durability. Despite your best efforts, if the cover tears or breaks down, you will end up with fiberglass contamination.

The most straightforward approach to avoid this problem is to place a mattress protector over the mattress, which you will want to do anyway to keep the mattress in good condition.

There are also many one-stop-shopping web retailers who have a reputation for selling mattresses with fiberglass, including Zinus mattresses:

• Amazon mattresses
• Wayfair mattresses
• Walmart mattresses
• Home Depot mattresses

How Do You Determine if the Zinus Mattress has Fiberglass?

Fiberglass is found beneath the mattress cover in Zinus mattresses. They encircle the foam to keep it from catching fire if it comes into contact with a flame, melting under the heat to create an improvised encasement.

It is not recommended to actively look for fiberglass while purchasing a mattress with fiberglass, such as Zinus. If you do this by opening up the cover, you may release fiberglass into the air, which can be disastrous for the immediate area.

Besides opening up a mattress you’ve just purchased, here are some other ways to tell if it includes fiberglass:

• If you buy your mattress online, the description should state how much fiberglass it includes.
• The materials used in your mattress should be listed on the labels. You can see if fiberglass is on the sticker or not, though it may be another term like “glass fiber” or “glass-reinforced plastic.”
• A mattress that advises you not to remove the cover also means the bed likely contains fiberglass.
• Price is another red flag that might help determine if a Zinus mattress contains fiberglass. Mattresses sold at modest to cheap rates frequently use low-cost components such as glass fibers. This flame retardant is uncommon in high-end luxury mattresses.

Reading information like this will also assist you in determining whether or not a Zinus bed includes fiberglass. You may always contact the company if none of these sites address your query. A well-known manufacturer, such as Zinus, should disclose the presence of fiberglass in its beds. If customer service tries to dodge the question without answering it, take it as a warning sign and look elsewhere.

It is fairly important that you can determine if a mattress has fiberglass in it before buying, especially if you have a sensitivity.

What if I Already Have a Zinus Mattress?

If you already own a Zinus mattress, it’s important to take proactive steps to minimize any risks associated with the fiberglass layer. Here’s what you can do:

Avoid Removing the Mattress Cover: Never remove the mattress cover, even for cleaning purposes. The cover is designed to contain the fiberglass layer and prevent it from becoming exposed.

Inspect for Damage: Regularly check the mattress cover for any signs of damage, such as tears, holes, or fraying seams. If you notice any damage, contact Zinus customer support for guidance on how to address the issue.

Use a Mattress Protector: To provide an additional layer of protection, consider using a high-quality mattress protector that fully encases the mattress. This can help prevent accidental damage to the cover and reduce the risk of exposure.

Handle with Care: When moving or handling your mattress, be cautious to avoid dragging or puncturing the cover, which could potentially expose the fiberglass layer.

If you suspect that fiberglass has already been released from your mattress, it’s important to take immediate action to clean up the affected area and prevent further exposure. You may need to consult a professional cleaning service experienced in dealing with fiberglass contamination.

Time to Decide to Replace a Zinus Mattress

Deciding when to replace a Zinus mattress involves considering several factors, including the mattress’s age, condition, and personal comfort. Signs that might suggest it’s time to replace your Zinus mattress:

Visible Damage: If you notice any damage to the mattress cover, such as tears, holes, or significant wear and tear, it’s crucial to consider replacing the mattress. Exposed fiberglass can pose serious health risks.

Sagging or Loss of Support: Over time, foam mattresses can lose their ability to provide proper support, leading to sagging or indentations. If your mattress no longer feels comfortable or is causing back or joint pain, it may be time for a replacement.

Worsening Allergies or Respiratory Issues: If you or your family members are experiencing an unexplained worsening of allergies, skin irritation, or respiratory issues, it could be due to fiberglass exposure or other allergens trapped in an old mattress. In such cases, replacing the mattress can improve your health and comfort.

Age of the Mattress: Most mattresses, including those from Zinus, have a 7-10-year lifespan. If your mattress is approaching or has exceeded this age, it may no longer provide adequate comfort and support, making it a good time to consider a replacement.

Should I Purchase a Zinus Mattress?

When considering whether to purchase a Zinus mattress, it’s important to weigh the benefits and potential risks. 

Zinus mattresses are popular for their affordability, comfort, and variety of models catering to different sleep preferences. They are particularly attractive to budget-conscious shoppers looking for a decent-quality mattress at a lower price point.

However, the presence of fiberglass as a fire retardant is a significant factor to consider. While many users have had positive experiences with Zinus mattresses, the potential health risks associated with fiberglass exposure should not be overlooked.

Consider purchasing a Zinus mattress if:

• You’re looking for an affordable mattress that offers decent comfort and support.
• You are aware of the presence of fiberglass and are committed to following the care instructions to avoid exposure.
• You plan to use a high-quality mattress protector for added safety.

Consider alternative options if:

• You’re concerned about the potential health risks associated with fiberglass exposure.
• You prefer a mattress without fiberglass or are willing to invest in a mattress that uses alternative fire-retardant materials.
• You have a history of skin sensitivity or respiratory issues that could be aggravated by fiberglass.

Protecting Yourself from Fiberglass in Mattresses

To protect yourself from potential exposure to fiberglass in mattresses, it’s important to take certain precautions:

• Never Remove the Mattress Cover: The most critical step is to avoid removing the mattress cover under any circumstances. The cover is designed to contain the fiberglass layer; removing it can release fibers into your home.
• Use a High-Quality Mattress Protector: Invest in a durable, fully encasing mattress protector. This adds an extra layer of protection between you and the mattress, reducing the risk of damage to the cover and exposure to fiberglass.
• Regularly Inspect the Mattress: Periodically check your mattress for any signs of wear, tears, or other damage to the cover. If you notice any issues, contact the manufacturer immediately for advice on how to proceed.
• Handle the Mattress Carefully: When moving or rotating your mattress, do so gently to avoid puncturing or tearing the cover. Dragging the mattress or placing sharp objects on it could damage the cover and expose the fiberglass layer.
• Keep Pets and Children Away: Ensure that pets and young children do not jump on or scratch the mattress, as this could potentially damage the cover and expose fiberglass.

How Do You Maintain a Fiberglass Mattress?

By following these care tips, you can help ensure that your fiberglass mattress remains comfortable and supportive for years to come. Proper maintenance not only extends the lifespan of the mattress but also enhances your overall sleep experience.

• Rotate your mattress every three to six months to promote even wear. This helps prevent sagging or indentations, which can develop if the mattress is used in the same position for an extended period. Regular rotation ensures that the mattress maintains its shape and provides consistent support.
• Vacuum your mattress regularly using a vacuum cleaner with an upholstery attachment. This helps remove dust, dirt, and allergens that can accumulate over time. Be gentle when vacuuming to avoid damaging the mattress cover.
• If you accidentally spill something on the mattress, clean it up as soon as possible. Use a clean, damp cloth to blot the area, then let it air dry completely. Avoid soaking the mattress, as excessive moisture can lead to mold and mildew growth.
• Ensure that your mattress is placed on a sturdy, supportive foundation or bed frame. A proper foundation prevents the mattress from sagging and helps maintain its structural integrity. Check the foundation regularly to ensure it remains in good condition.
• Although it might be tempting, avoid jumping on the mattress or placing heavy objects on it. Excessive pressure can damage the mattress and reduce its lifespan.
• To keep your mattress fresh, air it out occasionally. Remove all bedding and let the mattress breathe for a few hours. This helps reduce moisture build-up and can keep your mattress feeling fresh.
• If you need to store your mattress for an extended period, make sure it is stored flat in a dry, well-ventilated area. Avoid placing heavy items on top of it during storage, as this can cause the mattress to lose its shape.

Zinus Fiberglass-Free in 2025

In 2025, Zinus shifted in response to growing consumer concerns and legal pressures by introducing fiberglass-free mattresses. The move came after a series of lawsuits were filed against the company, causing significant harm to consumers. 

The lawsuits highlighted incidents where the fiberglass escaped from the mattress, leading to the contamination of homes and severe health issues for those exposed.

Acknowledging the gravity of these concerns, Zinus decided to eliminate fiberglass from its mattresses entirely. Instead, it adopted alternative fire-retardant technologies that provide the same level of safety without the associated risks. This decision was part of Zinus’s commitment to improving product safety and regaining consumer trust.

The introduction of fiberglass-free models reflects Zinus’s responsiveness to legal and consumer feedback and reinforces its dedication to delivering safe, comfortable, and reliable sleep solutions. 

Customers can now enjoy the benefits of Zinus mattresses with the added assurance that they are free from fiberglass, making them a safer choice for any household.

FAQs

Is there a case pending against Zinus mattress company due to fiberglass?

The growing number of reports of fiberglass in these mattresses has resulted in a Zinus mattress lawsuit. Several homeowners have filed complaints against Zinus, seeking reimbursement for damages. The lawsuit aims to represent anyone who purchased a Zinus mattress with glass fibers.

Did Zinus stop using fiberglass in their memory foam mattresses?

As of this writing, Zinus uses fiberglass in its beds. They still haven’t switched to a different, safer flame retardant. However, more individuals are aware of the hazardous fiberglass in Zinus mattresses.

Are Zinus mattresses dangerous?

CertiPUR-US® has certified the production of Zinus foams. As a result, they do not contain harmful compounds like formaldehyde.

However, CertiPUR-US® does note that they only look at the foams, not the flame barriers or surrounding textiles. The main issue is that fiberglass can harm your temporary respiratory health and taint your house if it escapes the mattress.

Do Zinus mattresses contain any chemicals?

Zinus beds cannot be classified as containing organic materials. They do, however, contain extremely few chemicals, and Zinus foams are CertiPUR-US® certified. As a result, you don’t have to worry about inhaling contaminants.

What are some chemicals that are used in mattresses as flame retardants?

Mattresses often contain various chemicals as flame retardants to meet safety regulations. These include Polyurethane foam additives, such as phosphates and nitrogen-based compounds, which are used to reduce flammability. 

Boric acid is a natural flame retardant often found in mattresses but can be irritating in large quantities.

Melamine is another flame retardant that releases water vapor when exposed to high temperatures to cool and suppress flames. 

Halogenated Flame Retardants (HFRs), like brominated flame retardants, effectively reduce flammability but raise concerns due to their persistence and potential toxicity. 

Graphite, found in some specialty mattresses, forms a protective char layer when exposed to high heat, acting as a flame retardant.

Can an air purifier remove fiberglass from the air?

An air purifier can help reduce the number of fiberglass particles in the air. The effectiveness of the air purifier depends on the type and size of the fiberglass particles. 

High-efficiency particulate Air (HEPA) filters are highly effective at capturing small particles, including fiberglass. A quality air purifier equipped with a HEPA filter can trap fiberglass fibers, reducing their presence in the air. 

However, HEPA filters are not foolproof and may not capture very small fibers or those that have not yet become airborne. Additionally, air purifiers will not remove fiberglass fibers that have settled on surfaces. 

To complement the use of an air purifier, thorough cleaning practices, such as vacuuming with a HEPA-equipped vacuum cleaner and wiping down surfaces, can help manage and reduce fiberglass contamination in the home.

Is it possible to obtain a Zinus mattress without fiberglass?

Fiberglass is present in all Zinus mattresses. As a result, if you seek a fiberglass-free bed, you might consider alternative manufacturers such as Amerisleep, which uses silica as a flame barrier. Many individuals like Zinus beds because of their low cost. These cheap mattresses, though, contain fiberglass.

Is a Zinus Mattress Right for Me?

Regardless of your opinion on the dangers of fiberglass or lack of, you will see that Zinus is one of the more popular low-cost mattresses in the United States. After learning that it includes fiberglass, you may be unsure if you should purchase a Zinus mattress.

Understandably, its pricing may sway you toward this brand. At this price, though, you may want to seek out a different fiberglass-free mattress with better protection from exposure. There are other mattresses under $500 to consider, after all.

Given that you won’t be able to obtain a Zinus mattress with no fiberglass, it is also worth considering spending more on a quality mattress. If you can stretch your budget and look at mattresses under $1000, you’ll find a number of affordable high-quality options that are free of fiberglass.

We do not advocate buying this bed for regular use if you are worried about fiberglass contamination because the cover will likely eventually wear out, and the fiberglass will pollute your room. While finding the best mattress can be challenging, it’s worth it to get a bed you’re comfortable with. If you must go with Zinus, avoid removing the cover and, if feasible, invest in a mattress cover.
