Do Purple Mattresses Have Fiberglass? What You Need to Know About Their Materials and Layers

If you’re searching for a mattress that’s both comfortable and safe, you’ve probably come across concerns about fiberglass in mattresses. This material is often used as a fire barrier, but it has raised red flags due to its potential to cause skin irritation and respiratory issues. So, the big question is: Do Purple mattresses have fiberglass?

Let’s clear the air and explore not only the answer to that question but also what materials are used in the construction of Purple mattresses.

Do Purple Mattresses Contain Fiberglass?

No, Purple mattresses do not contain fiberglass. This is one of the key safety features that sets Purple apart from many other mattress brands. Instead of using fiberglass as a fire barrier, Purple uses fiberglass-free, non-toxic flame retardants that are safe and effective.

The flame barrier in Purple mattresses is made from a knit blend of rayon, polyester, and silica—materials that meet federal fire safety standards without posing health risks. There’s no need to worry about fiberglass particles becoming airborne if the cover is removed or damaged, a concern that exists with some lower-cost memory foam mattresses.

If you’re specifically shopping for a mattress without fiberglass, Purple is a reliable and transparent brand to consider.

Why Avoid Fiberglass in Mattresses?

Some mattress manufacturers use fiberglass as a cheap flame retardant. However, if fiberglass escapes the mattress—often through a ripped cover—it can spread tiny glass shards throughout your home. Exposure can cause:

• Skin irritation
• Respiratory issues
• Contamination of furniture and air ducts

That’s why many consumers today are actively searching for fiberglass-free mattresses, and why Purple’s design is considered safer and more advanced.

What Materials Are Used in Purple Mattresses?

Purple mattresses feature a proprietary combination of materials engineered for support, airflow, and comfort—without sacrificing safety. Here’s a breakdown of the main layers:

1. Purple Grid (Hyper-Elastic Polymer)

The star of the show is the Purple Grid, a patented comfort layer made from a hyper-elastic polymer. It’s:

• Flexible and responsive to pressure points
• Naturally cool and breathable
• Hypoallergenic and free from fiberglass and toxic chemicals

This material gives Purple mattresses their signature feel—soft where you want it and firm where you need it.

2. Comfort Foam Layers

Under the Purple Grid, you’ll find layers of polyurethane foam that provide transition and support. These foams are:

• CertiPUR-US® certified (free from harmful chemicals, heavy metals, and ozone depleters)
• Designed for enhanced pressure relief
• Supportive without adding heat retention

3. Individually Wrapped Coils (Hybrid Models Only)

Purple Hybrid and Purple Hybrid Premier models include a base of individually wrapped coils that:

• Add bounce and edge support
• Improve durability
• Increase airflow

These coils are encased in fabric, helping reduce motion transfer and noise.

4. Support Base

• Foam models: High-density support foam
• Hybrid models: Reinforced coil system

These bases provide long-lasting structure and spinal alignment.

5. Fire Barrier and Mattress Cover

• No fiberglass fire barrier – Instead, a safe blend of rayon, polyester, and silica is used.
• The mattress cover is a soft, stretchy knit fabric that’s breathable and enhances the mattress’s contouring ability.

Is Purple a Fiberglass-Free Mattress?

Absolutely. If you’re looking for a fiberglass-free mattress that doesn’t compromise on comfort or support, Purple is one of the best options on the market. You’ll get:

• No fiberglass
• No toxic flame retardants
• Premium materials designed for comfort and cooling

In an era where mattress safety is just as important as pressure relief or motion isolation, Purple checks all the boxes.
