What is Fiberglass?

Why is it Used in Mattresses?

Definition of Fiberglass

Fiberglass is a synthetic material made from fine fibers of glass. In the context of mattresses, it’s often used as a fire barrier to meet safety regulations. Some people also refer to fiberglass as glass wool.

Composition and Properties

Fiberglass comprises silica, alumina, and other elements that melt together and spin into fine fibers. These fibers are woven into mats used as fire-retardant layers in some mattresses.

Fiberglass is known for being strong, durable, and resistant to heat and fire. However, if the fibers are disturbed, they can become airborne and potentially pose health risks.

Fiberglass: Reasons for Use in Mattresses

Fire Retardant Qualities

According to Poison Control, one of the main reasons fiberglass is used in mattresses is its flame retardant properties. Mattresses need to meet specific flammability standards.

Fiberglass effectively slows the spread of flames, providing an added layer of safety in case of a fire.


Fiberglass is often used in mattresses due to its cost-effectiveness. It’s a more affordable option compared to materials like wool or specialized chemical treatments that provide fire-retardant properties.

This allows manufacturers to produce mattresses at a lower cost, making them more affordable for consumers.

Are Fiberglass Mattresses Safe? Health Risks

Skin Irritation

If the fiberglass layer in a mattress is disturbed, the fine fibers can become airborne and settle on the skin.

This can cause irritation, itchiness, and even minor rashes for some folks. It’s particularly concerning for those with sensitive skin or existing skin conditions.

Respiratory Issues

Breathing in airborne fiberglass fibers can be risky for your respiratory system. It can cause symptoms like coughing, wheezing, and shortness of breath.

If you’re already dealing with asthma or COPD, you’ll want to be extra cautious, as long-term exposure could worsen things.

Indoor Air Quality

When the fine fibers of fiberglass become airborne, they can circulate throughout your home, contaminating the air you breathe.

Bad indoor air quality can worsen allergies and cause other health problems like headaches and tiredness. Plus, once those fibers settle, they’re a pain to eliminate completely. It will take a lot of cleaning or even some professional help.

This poses a long-term risk, especially for households with children, elderly members, or pets more susceptible to air quality issues.

How to tell if you have a Fiberglass Mattress

Check the Label

The most straightforward way to determine if your mattress contains fiberglass is to check the label.

Manufacturers are required to list the materials used in the mattress, including any fire-retardant materials like fiberglass.

How to read a Mattress Tag

Focus on the section that lists the materials used in the mattress. This is often found under headings like “Materials,” “Contents,” or “Made From.”

If you come across terms like “glass fiber” or “fiberglass,” it clearly indicates that your mattress contains this material.

Research the Mattress Brand

If the label is unclear or you’ve discarded it, research the brand and model of your mattress online.

Many manufacturers provide detailed information about the materials used in their products on their websites.

Contact Customer Service

When in doubt, contact the mattress manufacturer’s customer service for clarification. They should be able to provide information on whether your specific mattress model contains fiberglass.

Regulations and Standards

Federal Regulations on Flammability Standards

One key federal regulation impacting mattress manufacturing is the flammability standard set by the Consumer Product Safety Commission (CPSC). This standard, known as 16 CFR Part 1633, requires that all mattresses sold in the United States must resist the spread of fire to a certain extent.

This is often why some mattresses use materials like fiberglass as fire barriers. However, alternative materials meet these standards without posing the health risks associated with fiberglass.

Research and Data on Fiberglass Mattresses

Incidence of health issues related to fiberglass mattresses

Although exact numbers are hard to come by, anecdotal evidence and individual case studies suggest a correlation between health issues and exposure to fiberglass from mattresses.

These health issues range from mild skin irritation to more severe respiratory problems, emphasizing the need for caution when choosing a mattress with a fiberglass fire barrier.

Class Action Lawsuit

There are ongoing legal investigations into the health risks and property damage caused by fiberglass in mattresses. Lawsuits are being considered against manufacturers for not adequately warning consumers.

Issues range from respiratory problems to widespread home contamination. Zinus is notably facing multiple class action lawsuits for such concerns.

What is an Eco-friendly Mattress?

In a world increasingly concerned with sustainability and health, the term “eco-friendly” has become more than just a buzzword.

Definition of Eco-Friendly

An eco-friendly mattress is one that is made from sustainable, renewable resources and is free from harmful chemicals.


A non-toxic mattress is free from harmful chemicals like formaldehyde, phthalates, and volatile organic compounds (VOCs).

The mouthful of works are just substances that can off-gas and pollute your indoor air, posing health risks.


Organic mattresses are made from materials that are grown without the use of synthetic pesticides or fertilizers.


A fiberglass-free mattress is one that uses alternative fire-retardant materials.

Materials to look for in Eco-Friendly and Organic Mattresses

  1. Organic Cotton: Grown without synthetic pesticides or fertilizers. It is soft, breathable, and biodegradable.
  2. Latex: Harvested from rubber trees. It is a renewable and biodegradable material that offers excellent support.
  3. Organic Wool: Often sourced from sheep raised under ethical conditions. Wool is natural, renewable, and biodegradable and has natural fire-retardant properties.
  4. Hemp: Plant-based material that is durable, breathable, and grown without pesticides.
  5. Coconut Coir: Made from the husk of coconuts, it is renewable and biodegradable. It is often used as a firmer layer in organic mattresses.
  6. Organic Flax: Flax is a sustainable, biodegradable material often used as a fire barrier.
  7. Bamboo: It’s soft, breathable, and grows rapidly without pesticides.
