Best Mattresses without Fiberglass 2024

What Is the Nectar Mattress Company?

Nectar Mattress is a famous mattress brand that offers memory foam mattresses, made with a blend of durable and comfortable foams. They are owned by home furnishing company Resident, a parent company of other mattress brands like DreamCloud, Awara, and Level Sleep.

Nectar mattresses do not rely on flame retardant chemicals for safety. Evidence suggests they instead use fiberglass in the sock that encases their foam layers beneath the mattress cover. Should a fire break out in the bedroom, the sock suffocates the oxygen needed for fuel and the fiberglass melts to keep the insides from catching fire.

In October 2024, Nectar reached out to us and disavowed the use of fiberglass in their mattresses. However, they did not respond to our requests for elaboration on what they used instead. We suggest shoppers keep this lack of transparency in mind as they look at mattresses.

Why Do Nectar Mattresses Have Fiberglass?

Nectar mattresses do have fiberglass, which is often used in some of the most popular memory foam blends. Nectar mattresses have fiberglass included to provide additional fire retardant protection. Memory foam mattresses are prone to catching fire when exposed to an open flame, due to their synthetic materials. And the fiberglass provides an extra barrier to help prevent this from happening.

By law, all mattresses made in the USA must meet stringent flammability safety guidelines. In other words, a US-made mattress must be able to resist an open flame for a set amount of time, and fiberglass is a common way to do so. However, some people worry about potential fiberglass exposure while using these mattresses.

What Is Fiberglass?

Fiberglass is a material made from fine strands of glass that are woven together and reinforced with plastic. It is commonly used in mattresses as a more flame resistant and retardant addition, such as in Nectar memory foam mattresses.

Fiberglass is a popular component of many mattress types, particularly in memory foam mattresses. But why is fiberglass included in such a mattress? The answer lies in its aforementioned fire-retardant qualities.

Many mattress brands and companies use fiberglass as a cheap way to make mattresses safer for consumers. Fiberglass naturally does not burn easily, so it can help protect against fires caused by house fires, smoking or other sources of ignition.

However, there are some drawbacks to using fiberglass in mattresses. For example, the material can leak out and cause skin irritation or respiratory problems if not properly contained within the mattress layers. For this reason, many shoppers find it important to avoid mattresses that contain fiberglass, such as Nectar mattresses.

When buying a new mattress, it is important to look for one that uses a higher-quality flame retardant material such as sheep’s wool, flame-resistant plant fibers, graphite powder, etc., instead of relying on cheaper materials like fiberglass. This will help ensure that you get the best protection from your mattress without putting yourself at risk of health complications due to exposure to fiberglass particles.

Is The Nectar Mattress Safe To Use?

When it comes to fire safety, many consumers are asking if Nectar mattresses are safe. It is important to consider the flame retardant materials used in mattresses and if fiberglass contamination could be a concern.

Nectar mattresses do have fiberglass inside. This means that there is a potential risk of inhaling fiberglass particles from a Nectar mattress or getting it on your skin if the mattress cover wears away, as can happen with extended use.

You can use a mattress protector as an extra barrier against fiberglass exposure. However, this should be looked at as a stopgap measure rather than a true solution. It’s best to research all options carefully before making any decisions when it comes to buying a new mattress.

How Dangerous Is Fiberglass In A Mattress?

When it comes to buying mattresses, fiberglass is an important consideration. Many companies claim that their mattresses are made with the best quality materials, but if they contain fiberglass, it can pose a health hazard. As these tiny fibers can irritate the skin and cause rashes and even worse symptoms upon exposure, it’s important to exercise extreme caution when choosing a mattress.

The mattress industry has been using fiberglass in fire barriers for decades, as it is incredibly flame resistant and inexpensive. It’s been used in the home industry as insulation for similar reasons.

It should be noted that fiberglass isn’t the only potentially harmful ingredient mattress manufacturers use. The following are some of the more risky compounds utilized by manufacturers:

  • Boric acid
  • Oxide of decabromodiphenyl
  • Diphenyl ethers polybrominated
  • Melamine
  • Trioxide of antimony
  • Chloride of Vinylidene

Chemicals such as these are why many consumers wonder if memory foam mattresses are safe, and the answer usually boils down to “it depends on the manufacturer.”

However, this means that consumers need to be aware of what they are buying and make sure any mattress they choose doesn’t contain fiberglass. As such, it’s essential to check company claims against independent reviews from reputable sources before making a purchase of the right mattress. Ultimately, finding a quality mattress without fiberglass is the key to safety and comfort.

Signs of Fiberglass in a Mattress

If you’re wondering if your mattress has fiberglass, the best way to find out is to contact the manufacturer. However, not all manufacturers are reliable and honest, and you may encounter sellers who try to deceive or downplay that their mattresses contain fiberglass. Some typical signs your mattress may have fiberglass include.

Greenwashing terms: Greenwashing is 1 Verified Source National Library of Medicine (NIH) World’s largest medical library, making biomedical data and information more accessible. See the source when marketing uses misleading terms to make materials sound natural that are not. 

Price: As low-cost mattresses tend to use fiberglass as a cheap flame retardant, you want to be careful when looking at budget mattresses, particularly mattresses under $500.

Made in China: Mattresses made in China and elsewhere overseas may also include fiberglass, for the same cost-cutting reasons. We should note that in 2018, Nectar settled with the Federal Trade Commission after falsely claiming its mattresses were assembled in the United States, when really they were made in China.

Reminder, all Nectar mattresses are made with fiberglass. This means that the Nectar mattress is not safe from any potential health hazards that could arise from glass fibers. Other brands that have also come under question for using fiberglass include:

So when you’re looking for a mattress that offers both comfort and safety for a good night’s sleep without the use of fiberglass, Nectar memory foam mattresses may not be the best choice for you.

Can I Clean Fiberglass out of a Mattress?

Removing fiberglass from a mattress is all but an impossible task, as there’s no feasible way to open up a mattress cover and safely extract every single particle of fiberglass. Even if you were to accomplish it, the gains would hardly be worth it as you would have removed the primary material used to create a flame-resistant mattress. And it’s a challenge to clean up fiberglass after it’s escaped the mattress.

If you’re ready to purchase a new mattress but want to make sure it’s free of any hazardous materials like fiberglass, then researching some of today’s best mattresses is a good idea. For those looking for an alternative, there are many other mattress brands, companies and manufacturers who offer mattresses with wool, plant fibers, silica, and flame-resistant textiles.

Doing so can help ensure that you buy an entire mattress that won’t put your health at risk later down the road. So don’t forget to check reviews and look for any warnings about potential hazards when looking for a new type of mattress.

Frequently Asked Questions

Why do so many mattresses have fiberglass?

Mattress makers frequently use fiberglass to make cheap mattresses and satisfy fire safety regulations. When exposed to flame, the fiberglass melts and encases other flammable materials to ensure sleeper safety. However, when mattress coverings are unzipped or removed, these same sleepers can suffer from fiberglass exposure.

Is it safe to sleep on a mattress with fiberglass?

The bed should be secure as long as the fiberglass is kept inside the mattress. Still, it’s wise to weigh up the potential effects of fiberglass exposure if you’re debating replacing your mattress.

Exposure to fiberglass can cause coughing, a sore throat, red eyes, stomach problems, itchiness, and other irritation symptoms. There are no known long-term health risks associated with it, but more research may be required to state definitively that fiberglass is completely without long-term risks.

How do I know if my mattress has fiberglass?

Usually, your mattress label should clearly state this. If the label on your mattress reads “XX% glass fiber” or similar terms such as glass wool, that means fiberglass is present. Do not remove the cover as this is what causes the fiberglass fragments to be released into the air.

You can also inquire with a company about what materials they use to meet U.S. fire safety standards. Customer service should provide a straightforward explanation if you directly ask whether or not they use fiberglass inside their mattresses.

What are the symptoms of fiberglass exposure?

After being exposed to fiberglass, your eyes may become red and you have itchy skin. Inhaling fibers may also cause soreness in the nose and throat. Such fiberglass exposure can make asthma and bronchitis worse. If fibers are swallowed, a stomach ache and other digestive issues may result.

Fiberglass exposure symptoms can linger because of free-floating particles in the air. These particles can be difficult to clean up without specialty equipment like a HEPA vacuum cleaner, which is why it’s often best to minimize the chances of fiberglass exposure with a mattress free of fiberglass.

Do all memory foam mattresses have fiberglass?

No, not all memory foam mattresses have fiberglass. The type of flame-resistant barrier material used varies across memory foam, latex, and more traditional mattresses.

It’s not difficult to locate a good memory foam mattress made without fiberglass, but they can be expensive. Most foam mattresses created with this material come from low-cost manufacturers.


Nectar mattresses are a popular choice for those looking for a quality affordable mattress. However, it is important to be aware of the presence of fiberglass in a mattress before making a purchase, as it can be dangerous if exposed or inhaled.
