If you’re looking for a fiberglass free mattress with natural materials, we’ve ranked your top selections based on safety, comfort, and affordability.

If better sleep is on our “in” list for 2024, toxic mattresses are certainly “out.” That includes mattresses laden with harmful chemicals like fiberglass — a combination of glass and plastic used in mattresses as a cost-saving insulation material and flame retardant. 

According to a study in the International Journal of Environmental Research and Public Health, it’s not always entirely clear what compositions make up a mattress, even if the mattress is marketed as chemical-free. How fun for consumers, right? And fiberglass is one of those chemicals. Because it’s woven into the mattress and only visible if you remove the mattress cover, it can go unnoticed unless you read the label. (This study specifically found that two of four tested mattress covers contained more than 50 percent fiberglass, posing possible risks to consumers.)

Why should you choose a fiberglass free mattress?

Consumer health is the primary concern behind fiberglass mattresses. Fiberglass can cause skin irritations and respiratory issues, especially if the mattress becomes damaged and the particles are airborne. Long-term exposure has even been linked to lung disease. Thankfully, there are better options. Wool, cotton, polyester, and rayon are a few examples of fiberglass alternatives in mattresses. 

When shopping for your next mattress, it’s essential to find out if the materials and insulation contain fiberglass. Manufacturers are legally obliged to disclose this information — all materials and their percentages must be listed on labels. Reading each ingredient and inquiring with the company if you have questions is a good first step. 

Additionally, you can look for brands that have organic and nontoxic certifications. While you’ll still want to ensure no fiberglass is listed on the label, sticking with a brand notorious for safe materials is a good bet.

Topping our list for organic, fiberglass free mattresses, we love Birch for its impressive list of organic certifications and materials, including the use of 100% organic wool from New Zealand as a fire retardant solution (the brand guarantees zero fiberglass in its mattresses). These mattresses are also hypoallergenic and use anti-microbial materials, making them an excellent option for those with allergies or respiratory sensitivities. Best of all, the 100-night sleep trial allows you to test this one out in your home to see if it’s a good fit for you and your family. (That’s right, Birch makes a fiberglass free mattress size for kids and adults!)

Our Editor’s Review | “After a month of sleeping on our Birch Luxe mattress, my husband and I are well-rested and clear on what we’ve missed out on all these years. We are delighted with this mattress; our 8 and 10-year-old daughters agree.

When it comes to fire retardants, Avocado uses GOTS certified organic wool instead of fiberglass (wool is naturally flame-resistant). The California-based brand boasts itself on the strictest organic and nontoxic certifications, so, of course, this is no surprise. Avocado is often one of our top picks for mattresses, especially when switching to a bed you (and your family members) can sleep on for years and years to come. We especially love that every mattress is handmade in sunny California and GREENGUARD Gold certified for low emissions. 

Our Editor’s Review | “Since receiving the Green Mattress, I’ve been getting better rest, and my sleep scores have reflected that. My chiropractor has noticed my spine health is looking great, too.

In addition to the natural and safe materials, we love the nine-inch contouring support core for pressure relief. This bed makes us feel like we’re protecting our health and improving our sleep, which is really all we could ask for when it comes to a mattress. Oh, and the forever warranty is a very nice incentive.
