We can confirm that Nolah mattresses do not contain fiberglass. However, they do use silica as a flame retardant.

Where are Nolah Mattresses Made?

Nolah mattresses are made here in the US. One of the signs of mattresses with fiberglass is that they are often imported from China or Asia. In the East, the mattress manufacturing standards aren’t as strict as here in the US. Therefore, most beds there use fiberglass as a flame retardant because it is a cheap material.

The fact that Nolah mattresses are made here in the US under stringent manufacturing regulations is more confirmation that they do not use fiberglass.

What are Nolah Mattresses Made Of?

Since we are looking into the materials Nolah mattresses are made of, it’s also crucial that we list other ingredients you can find in these beds.

In any Nolah mattress, you will find an organic cotton cover. This is used to add comfort and also make the mattress surface more breathable. Cotton is a pretty safe material and you won’t get any allergic reactions from sleeping on it.

Beneath the cover, you will find a silica flame retardant. It’s pretty lightweight and thin. Therefore, you won’t even feel its presence. Next to the flame retardant is AirFoam, which is a version of memory foam made by Nolah mattress. AirFoam is free of viscoelastic materials which trap heat. Instead, it has more channels that promote airflow within the mattress.

Below the AirFoam, you will find regular memory foam. This memory foam is denser and offers extra support and bounce. In the base layer at the bottom, there is a seven-inch high-density foam that supports all the layers on top. In the hybrid model, you will find coils instead of memory foam.

What is Fiberglass and Why Is It Used in Mattresses?

As you try and find out if Nolah mattresses contain fiberglass, you need to understand what this material is and why is it used in some mattresses.

Fiberglass is a woven layer of reinforced plastic and glass. It’s an excellent flame retardant that protects flammable mattress materials. When it was first manufactured, fiberglass was commonly used in construction for insulation. With time, it entered the mattress industry and today, you will find it below most mattress covers.

Manufacturers like using fiberglass as a flame retardant because it’s cheap, widely available, and a good fire barrier.

Is Fiberglass in a Mattress Dangerous?

As long as fiberglass remains woven tightly beneath your mattress cover, you don’t have to be afraid of it. But if you remove the cover of a fiberglass mattress or if the cover gets torn, these particles will escape into the air and severely contaminate your home.

When fiberglass particles escape your mattress, they spread to the bedding and surrounding furniture or clothes. These pieces of glass don’t come off easily and if you touch them with bare skin, you may experience a rash, an itch, or blistering. If you happen to breathe in these fiberglass particles, you may start sneezing and feeling irritation in your mouth, nose, and throat. You are at higher risk of getting these symptoms if you are asthmatic.

It’s these side effects that mattress brands like Nolah have decided not to use fiberglass.
