How to tell if mattress has fiberglass?


When it comes to purchasing a mattress, it’s important to consider various factors such as comfort, support, and durability. However, one concern that often arises is the presence of fiberglass in mattresses. Fiberglass is a material commonly used in insulation, but it can also be found in some mattresses. In this article, we will explore how to tell if a mattress has fiberglass and discuss the potential risks associated with it.

Understanding Fiberglass in Mattresses

Fiberglass is a type of reinforced plastic made from fine fibers of glass. It is known for its strength and heat resistance, which makes it a popular choice for insulation in buildings and appliances. In mattresses, fiberglass is sometimes used as a fire barrier or as a component of the mattress cover.

Visible Signs

One of the most obvious signs that a mattress contains fiberglass is the presence of small white particles or fibers on the surface. These particles can be easily seen and may resemble tiny pieces of cotton or lint. If you notice any unusual white debris on your mattress, it is advisable to inspect it further for fiberglass.

Inspecting the Cover

To determine if your mattress contains fiberglass, you can inspect the cover. Look for any labels or tags that indicate the use of fiberglass as a fire retardant or fire barrier. Manufacturers are required to disclose this information, so it should be mentioned on the mattress or its packaging.

If the cover does not provide any clear indication, you can try peeling back a corner of the fabric to check for fiberglass. Be cautious while doing this, as fiberglass particles can become airborne and cause skin irritation or respiratory issues. It is recommended to wear gloves and a mask during this inspection.

Professional Inspection

If you are unsure about the presence of fiberglass in your mattress, you can consider seeking professional help. There are companies that specialize in mattress inspections and can provide accurate information about the materials used. They have the necessary expertise and equipment to detect fiberglass or any other potentially harmful substances.

Risks Associated with Fiberglass

While fiberglass is generally considered safe when properly contained, there are some risks associated with its exposure. The fine fibers can become airborne and easily irritate the skin, eyes, and respiratory system. Inhaling or ingesting fiberglass particles can cause discomfort, coughing, itching, and redness.

If a mattress containing fiberglass is damaged or improperly handled, the fibers can be released into the air, posing a risk of inhalation or skin contact. This is why it is crucial to handle mattresses with fiberglass carefully and avoid tearing or damaging the cover.


In conclusion, determining if a mattress contains fiberglass can be done through visible signs such as white particles on the surface or by inspecting the mattress cover for labels indicating the use of fiberglass. It is important to handle mattresses with fiberglass carefully to avoid any potential health risks associated with the release of fiberglass particles. If in doubt, seeking professional inspection can provide accurate information about the mattress composition.
