Do Latex Mattresses Have Fiberglass? 

A while back, fiberglass was mainly used in memory foam mattresses. However, these days, you can find this harmful flame retardant in innerspring and even hybrid mattresses. But what about latex mattresses? Can you find fiberglass in this type of mattress? Well, that’s going to be the main focus of today’s article.

Do Latex Mattresses Have Fiberglass?

The chances of finding fiberglass in a natural or organic latex mattress are very low. As a matter of fact, it’s next to impossible. Mattress manufacturers who undergo the rigorous process of harvesting and processing natural latex are more likely to use an organic flame retardant instead of fiberglass. This is done to keep mattress manufacturing standards high.

Unlike memory foam, latex mattresses are designed with luxury, comfort, and quality in mind. That’s why they have a higher price tag. Latex is a natural mattress material or ingredient. Therefore, it would be illogical for a brand to pair it up with dangerous materials like fiberglass.

However, there are some exceptions when it comes to the use of fiberglass in latex mattresses. Are you familiar with synthetic latex? This is a material that is produced to copy the features of natural latex. Instead of being harvested, synthetic latex is manufactured using petrochemicals.

When it comes to synthetic latex mattresses, there is a probability of finding fiberglass in such a bed. The reason synthetic latex mattresses exist is because they are a cheaper alternative to organic latex. And when cheap is part of the discussion, fiberglass can easily find its way in because it is a cost-effective flame retardant.

The key takeaway here is that; It’s rare for natural latex mattresses to have fiberglass. However, in synthetic latex mattresses, there is a possibility of finding fiberglass under the cover. If you are shopping for the latter type of latex mattress, please proceed with caution.

What Fiberglass Alternatives Do Latex Mattresses Use?

Instead of fiberglass, organic latex mattresses use natural flame retardants like wool or cotton. When you look at popular latex mattresses like the Zenhaven or Saatva Latex Hybrid, you will notice that they strictly use a natural thistle barrier that’s made out of wood pulp.

These fiberglass alternatives in latex mattresses are way better because they are safer. Unlike fiberglass which will irritate your throat or skin, natural flame retardants have no side effects when you are exposed to them. This means that every time you go to bed, you don’t have to worry about a harmful flame-retardant leaking through the cover and risking your health.

Sometimes, latex mattresses, especially the synthetic versions can use silica or rayon instead of fiberglass. Before buying a latex mattress, it’s crucial to figure out the flame retardant that is used by that particular brand. Above, we have shared a perfect example of Saatva who only use a natural thistle barrier in their latex mattresses.

It’s important to mention that these alternatives are equally as effective as fiberglass when it comes to preventing the spread of fires in mattresses. Therefore, your latex mattress with a natural flame-retardant will be sufficiently protected in case of a fire outbreak.

What is a Latex Mattress Made Of?

Latex mattresses are made out of the sap of a rubber tree. These trees grow natively in the Amazon but they are also grown here in the US under regulated conditions.

Latex beds are usually divided into two;

  • Dunlop Latex – The Dunlop latex is poured into a mould in one step which results in a mattress that’s softer at the top and firmer at the bottom. This unique combination offers exceptional pressure relief and comfort.
  • Talalay Latex – Talalay latex is made through several steps. The sap is partly poured into a mould and allowed to expand in a vacuum. This results in a mattress that has a consistent feeling from the bottom to the top.

Apart from these two types of latex, this mattress type is also combined with other natural materials to promote comfort and breathability. You can always confirm what your latex mattress is made of by going through the label or description.

How Can I Tell If a Latex Mattress Has Fiberglass?

Because of synthetic latex mattresses, there is a probability of finding fiberglass in some of these beds. To ensure you completely avoid this flame retardant, here are some ways you can check if a latex mattress has fiberglass;

  • If fiberglass is listed on the label. If you see XX% fiberglass, glass fiber, or fiberglass-reinforced plastic, then that latex mattress contains fiberglass.
  • If you are not allowed to remove the mattress cover, there is a good chance that fiberglass is woven below the cover.
  • If the manufacturer doesn’t want to disclose what flame retardant they are using, it’s probably fiberglass.
  • If there are allegations of fiberglass usage from other customers. Never ignore a comment about fiberglass when shopping for latex mattresses.

Is Fiberglass in Latex Mattresses Safe?

Even though fiberglass isn’t commonly used in latex mattresses as is the case with memory foam beds, it’s crucial to familiarize yourself with the safety concerns associated with this material.

As long as fiberglass remains intact inside your latex mattress, you need not be worried. However, when it starts leaking through the cover, then you, your family, and your home will be in big trouble. Sleeping on a fiberglass latex mattress is quite dangerous. These particles can scratch your skin leading to the development of rashes or an annoying itch.

You can also inhale some fiberglass particles which will irritate your respiratory system. The same thing will happen when fiberglass gets into your eyes. Apart from putting your health at risk, fiberglass leaking from a latex mattress can spread all over your home through the air. It’s stubborn to remove from clothes and furniture and you may end up discarding these items.

Fiberglass is not a safe material to have in your latex mattress. That’s why you should avoid it as much as possible.

Why Do Some Manufacturers Use Fiberglass in Latex Mattresses?

The few latex mattress brands that use fiberglass in their beds do so because it is a cheap material that enables them to pass the flammability regulations. In 2007, the US Consumer Product Safety Commission passed allow requiring all mattresses to have a flame retardant. This law was enforced to keep sleepers safe because mattresses are mostly made using highly flammable materials.

Even though there are other safer flame retardants, some manufacturers prefer fiberglass because it is inexpensive. Therefore, its usage keeps mattress production costs low. The use of fiberglass in latex mattresses is unethical because these companies are well aware of the dangers of this flame retardant.

What Should You Do If a Latex Mattress Has Fiberglass?

After discovering your latex mattress has fiberglass, do not remove the cover to check what’s inside. Instead, carefully place the mattress in a zippered plastic bag and get rid of it. This applies to fiberglass mattresses whose covers are torn or worn out. If the cover is in good condition, look for a mattress protector and put it over the latex mattress. This will keep you safe from the fiberglass.

In the future, when you are buying a latex mattress, always confirm that it does not contain fiberglass. This will minimize any risks and you will enjoy peace of mind knowing that you are safe.

What are the Advantages of Latex Mattresses?

The fiberglass issue aside, what makes latex mattresses better than other types of beds? We all know that they are organic. But are there other benefits of sleeping on such a mattress? Let’s find out!

  • Latex mattresses are durable – The rubber tree sap is capable of creating a highly durable mattress that will resist sagging for years. it doesn’t matter whether you are a light or heavy sleeper, a latex bed will maintain its shape and perform better every night.
  • Latex is elastic – Because latex is an elastic material, it conforms better to your body shape, movements, and weight.
  • Latex is hypoallergenic – Are you always sneezing every morning because of dust or hay? You need to get yourself a latex bed. Due to its structure, latex is more resistant to dust mites and other allergens. You will always wake up feeling rejuvenated and fresh.
  • It’s organic and environmentally friendly – The trees from which latex is harvested produce millions of tons of oxygen per annum. This makes latex mattresses quite eco-friendly.

On the downside, latex mattresses tend to be very heavy. Latex is a dense material and when it’s processed into a mattress, it’s heavier than the typical memory foam. These beds are also very costly. That’s attributed to the intense manufacturing process.


Most latex mattresses on the market do not contain fiberglass. However, there are few models that do, especially those made out of synthetic latex. If you are shopping for a quality latex bed, it’s best to consider fiberglass-free mattresses that use safe flame retardants like wool, cotton, and plant-based fibers.
