Do All Memory Foam Mattresses Have Fiberglass? No.

Do All Memory Foam Mattresses Have Fiberglass - Feature Image

Sure, you expect natural mattresses like latex to come with wool or cotton instead of fiberglass for the fire barrier, but if memory foam mattresses don’t have fiberglass, what do they have? Do all memory foam mattresses have fiberglass?

Luckily, the answer is no. There are a ton of memory foam mattresses you can buy that have NO fiberglass at all. The ones that don’t have fiberglass usually use silica, sometimes mixed with wool to create the fire barrier. I’ve seen a ton of articles out there telling you about other mattress types that don’t have fiberglass, but I want to reassure you here that you CAN buy a memory foam mattress without fiberglass!

Here’s a list of 5 great memory foam mattresses with NO fiberglass:

  • Puffy. Puffy have a range of 3 well designed memory foam mattresses, all made in the USA. I talked with their customer service team to confirm there is no fiberglass inside their mattresses: instead they use a mixture of silica and wool. If you’re wanting a hybrid mattress that blends a coil support core with memory foam comfort layers, Puffy is the right choice for you. Learn more about the Puffy range here.
  • Tuft and Needle Original. This is a great mattress if you’re looking to buy your memory foam mattress on Amazon. You get a 100 night sleep trial, which is actually quite rare for Amazon. I’ve seen their customer service reps guarantee in the Amazon questions that there’s no fiberglass in this mattress. Do note this is not the case for all T&N mattresses, I’m talking specifically about the ORIGINAL. The Mint is also fiberglass free, but please note that the Tuft & Needle Nod and Nod Hybrid are NOT
  • Tempur-Pedic. Can you even talk about memory foam without mentioning the original brand? Tempur-Pedic mattresses have removable covers and no fiberglass, but they do cost quite a lot more than others I’ve listed.
  • Casper. Another well known brand that is sold on Amazon, the Casper Element mattress is a budget friendly option that doesn’t have any fiberglass. Hooray!
  • Snuggle Pedic is another amazing US made mattress available on Amazon with a silica fire barrier, but they’re so popular they are currently out of stock. Watch this space to see when they are back online.

Which Ones DO Have Fiberglass?

Here’s a list of 5 popular Amazon mattresses that DO have fiberglass:

  • Zinus
  • Classic Brands
  • Vibe
  • Ashley Furniture
  • Amazon Basics

Here’s some other brands that also use fiberglass:

  • Purple
  • GhostBed
  • DreamCloud
  • Nectar

Note: I couldn’t actually get a straight answer out of DreamCloud/Nectar (they’re the same company) which makes me assume they DO use it. Also, if you can’t get a straight answer from a company do you want to buy from them?

How Do I Know If My Mattress Has Fiberglass?

Do All Memory Foam Mattresses HAve Fiberglass - Zinus Label

There are three ways to tell if a mattress has fiberglass inside:

  1. Read the label to find what the mattress is made of. You’re looking for words like “fiberglass” (obviously), “glass wool”, or “glass fiber”
  2. Check your mattress instructions. If it states “do not remove the cover” (or words to that effect) that’s usually because there’s fiberglass in it. HOT TIP: some mattresses have zips on the cover, even though they have a “do not remove cover” warning. This zip is part of the manufacturing process, not an invitation to remove the cover. If you find yourself with a mattress that has a zip AND an instruction to never remove the cover, don’t touch that zip!
  3. Can’t find either of the first two? Here’s when I would assume a memory foam mattress contains fiberglass:
    • It was cheap (I’ll define this as under $500 for a Queen or King size mattress) AND
    • It’s made in China

What To Do If It Does:

So you’ve realized your memory foam mattress contains fiberglass. First of all, don’t panic! The fiberglass isn’t toxic, but it will be annoying and even hazardous if it gets out of the mattress (more on that further down the post). Here’s how you deal with your mattress to keep the fiberglass in:

  1. Don’t remove the cover. Fiberglass is used as a fire retardant layer above the memory foams under the cover. Remove the cover and you risk unleashing the fiberglass. Keep it contained!
  2. Use a mattress protector. If the mattress cover gets a hole in it, fiberglass could escape through it. Remember, these are often cheap mattresses, so the cover material may be thin or less durable than more expensive brands. Cover your mattress with a good quality protector as insurance against holes (and to extend the life of your mattress).
  3. Consider replacing it. If the idea of fiberglass in your mattress is just really freaking you out, it would be worth your peace of mind to just replace the mattress with a mattress that does not contain fiberglass. I’ve listed some great options for you earlier in this post.

Why Do Some Memory Foam Mattresses Even Have Fiberglass?

Why It’s Used

In the USA, all mattresses are required under federal law to have some sort of fire barrier or fire retardant in it.

Fiberglass is a popular choice of fire barrier because it’s low cost and non toxic. In the event of a fire it will melt in on itself (like liquid glass) without releasing toxic fumes.

While fiberglass is non toxic, (we use fiberglass all through our houses for insulation, etc), but it can be really annoying if it gets into the wrong spaces.

Why It Can Be A Problem

Ever touched an insulation panel that goes in a wall? Chances are it made you itchy. Fiberglass fibers are extremely fine but pointy, which can cause itching and irritation for some people.

If fiberglass escapes the mattress, it will be very hard to clean up. The fine particles can end up in your bedding, your clothes, your floor… and you could have to pay a lot of money to remove them.

This short video highlights both the hazards of fiberglass if it escapes from a mattress, and also how it is an EXTREMELY EFFECTIVE fire barrier (watch the mattresses burning at around 2 minutes in).
