There are SO many memory foam mattresses that DO have fiberglass that it makes it hard to find the ones without it. I’m sure that if you’re here reading this article you’ve seen the issues that fiberglass can cause, and you’re wanting to steer well clear of it. Lucky for you, I’ve got 3 memory foam mattress without fiberglass options for you where I’ve seen confirmation direct from the brand that their mattress is indeed fiberglass free. Wohoo!

Memory Foam Mattress Without Fiberglass: Close-Up On The Top Three

1. Tuft & Needle Original: A Wildly Popular Top Seller I Couldn’t Leave Out

TUFT & NEEDLE - Original Queen Adaptive Foam Mattress, CertiPUR-US, 100-Night Trial
  • Pressure Relief - Our T&N Adaptive foam is engineered based on customer feedback, and provides pressure relief where you need it most. An open-cell structure provides a flexible sleep surface that adjusts to you as you move throughout the night.
  • Support - The T&N Original Mattress is ideal for back and stomach sleepers. We complemented the T&N Adaptive foam with a base layer of supportive foam to prevent sinking into the mattress.
  • Cool Sleeping - Our open-cell cooling technology foam works with the heat-conducting graphite and cooling gel-infused in our T&N Adaptive foam to wick away heat and moisture for a deep, restful sleep.
  • Versatility - We designed our mattress to be compatible and complementary with most frames and foundations including: traditional frames, box springs, platform frames, slatted frames, bunky boards, and adjustable frames
  • Questions - We pride ourselves on customer service and urge you to reach out to us directly if you have any questions at any point, our expert customer service team will be available to help you through any of your hesitations, problems or questions

What Do They Use Instead Of Fiberglass?

Tuft & Needle use a totally different fire barrier than other brands in their memory foam mattresses without fiberglass (the Original and the Mint): they use salt! Yes, you read that right, they use salt in the sock that encases the foams.

A lot of people seem to doubt that the Tuft & Needle Original mattress is actually fiberglass free, here’s a shot of them confirming over (and over) that yes, it is fiberglass free. I even asked them myself so you can be really sure.

Tuft & Needle Original Memory Foam Mattress Specs

  • 100 Night sleep trial (very rare for mattresses sold on Amazon, you’re usually stuck with the 30 day returns policy)
  • Made in USA
  • Medium firm feel will feel comfortable to most people
  • Breathable cooling cover
  • 2 foam layer construction, with graphite and cooling gel infused into the memory foam

2. Puffy Royal: Best Luxury Mattress Packed Full Of Features

What Do Puffy Use Instead Of Fiberglass?

Puffy use silica in their mattress fire barrier, mixed with wool. The wool is a nice luxury touch, and contributes to the char barrier while also adding temperature regulating benefits.

I didn’t save a picture for you (my apologies!) but I DID chat directly with the Puffy customer service team in March 2021 to confirm this for you.

Puffy Royal Memory Foam Mattress Specs

  • 101 Night sleep trial and unbeatable lifetime warranty
  • Made in USA
  • Medium plush feel – I think this mattress will be comfortable for everyone except heavier stomach sleepers
  • Extra stretchy cover embossed with Puffy’s signature cloud design
  • Luxury 14 inch height with 4 layers of comfort foams designed for targeted support (one of them has different pressure zones), temperature regulation (gel beads and ventilation channels) and deep comfort

The coils in combination with the foams in this mattress gives you all the high quality features you could ever ask for really. Puffy Royal is pretty much my idea of an ideal mattress.


3. Casper Element – Best Budget Choice

Casper Sleep Element Mattress, Queen
  • Balance: The Element is engineered to combine both softness and support. The top layer of memory foam comforms to your body to relieve pressure.
  • AirScapeTM: A layer of AirScapeTM perforated breathable foam increases airflow and circulates air so you don't get too hot at night. The tiny holes move hot air and body heat away.
  • Support: The durable base foam is engineered to prevent sinking and sagging while supporting your whole body.
  • Certified by our Sleep Lab
  • 100 night trial and free returns within 100 days of receipt of shipment on products sold by Casper

What Do Casper Use Instead Of Fiberglass In The Element Mattress?

Like many other fiber glass free memory foam mattress brands, Casper has also opted for silica in their Element mattress. Here they blend it with rayon (cotton) and polyester.

Mattress Specs

  • 100 Night sleep trial (very rare for mattresses sold on Amazon, you’re usually stuck with the 30 day returns policy)
  • Eco friendly stretch cover made from recycled materials – a really nice touch.
  • Medium firm feel
  • 10 Inch height with 2 foam layer construction (this is how Casper keeps the price low: using two foam layers instead of 3)
  • The top foam layer is perforated to allow airflow

I think it’s pretty incredible that Casper can offer a memory foam mattress without fiberglass at this price point, AND with a 100 night sleep trial. This is pretty exceptional in my opinion. Great budget choice.
