What Does Memory Foam Do?

Contouring & Pressure Relief

When you lie on a memory foam mattress or pillow, your body heat softens the foam in the areas where you exert the most pressure, allowing the material to contour closely to your body shape.

This provides excellent support and helps relieve pressure points, reducing the risk of pain in areas like the shoulders, hips, and back.

Motion Isolation

Memory foam absorbs energy and isolates motion, which means that when one person moves or gets out of bed, their partner is less likely to be disturbed.

This feature is particularly beneficial for couples or those who share a bed with pets or children.

Supports Spinal Alignment

Due to its contouring nature, memory foam can help maintain the natural curvature of the spine by providing even support along the body’s length.

This can be especially beneficial for side sleepers.

Why Do Memory Foam Mattresses Have Fiberglass??

Here are the primary reasons why some memory foam mattresses comprise this substance.

Flame Retardant

First, several mattress companies have added materials to improve the performance of consumer product safety at their will over the years.

Besides that, Lawmaking has intervened in the production of these products. According to SPSC regulations, all furniture products must include flame retardants. Hence, materials like fiberglass are compulsorily added to a mattress.

All mattresses, including memory foam, are effortlessly set on fire. The main reason is these items are made of synthetic materials, making them easily flammable and release toxic when burnt.

Cheap Cost

Among flame retardant elements, this is one of the cheapest, most effective fireproof, and long-lasting supplements. Likewise, it is the fireproof barrier meeting the fire requirements of USA Federal Law.

However, not all memory foam mattresses contain fiberglass. Some types of foam mattresses use high-quality materials to ensure the risks to their user’s health.

Highly Heat Resistant

Fiberglass in memory foam mattresses offers excellent heat resistance and an insulating effect. On the other hand, this element is a warmth absorber. Thus, it is employed to adjust sleep conditions and product safety to compensate for this flaw.

Fiberglass is a cheap cost and effective fireproof material

What Risks Can You Face If Your Mattress Has Fiberglass?

Although this material has some benefits, especially its role as a fire retardant in the foam mattress to follow safety commission. However, it still causes problems for users. Here are some of the risks we can face due to fiberglass:

Risk To Health

If you need to remove the mattress cover, your room’s atmosphere may get polluted because of fiberglass particles. It can irritate your nose, throat, and eyes, especially causing respiratory diseases.

The cost you have to pay even is higher if you let these shards fly into your air conditioner. Fiberglass particles will spread throughout your house when you turn on this device.

Air Pollution

Some consumer products are reported that they even have to move to another new accommodation because the air in their house is full of fiberglass particles.

Wool: Wool is a natural fire retardant. It’s inherently resistant to flames and can char without burning. Many organic and natural mattress brands use wool layers as a fire barrier, providing both safety and comfort.

Organic Cotton combined with Baking Soda: Some manufacturers use a combination of organic cotton and baking soda to create a fire barrier. While not as inherently flame-resistant as other materials, when used in specific combinations, they can meet fire safety standards.

Silica: Silica-based fire barriers are derived from sand and are used as a safer alternative to fiberglass. They are non-toxic and can effectively resist flames without the potential health concerns associated with fiberglass.

Natural Latex: Natural latex, derived from the sap of rubber trees, is less flammable than synthetic foams. Some mattresses use thick layers of natural latex as both a comfort layer and a fire barrier.
