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 this year, 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.)
What is fiberglass?
Fiberglass might not be the first thing that comes to mind when you think about mattresses, but it plays a surprisingly important role behind the scenes. In many mattresses, thin layers or fibers of fiberglass are added as a flame-retardant barrier, helping the bed meet safety standards without relying on harsh chemical treatments. It’s lightweight, effective, and unobtrusive — hidden beneath fabrics and foam, doing its job without changing the feel of your sleep surface. That said, because fiberglass can irritate skin and lungs if exposed, proper encasing and handling during manufacturing and unpacking are crucial. In essence, it’s one of those invisible materials that quietly makes mattresses safer, proving that some of the most important innovations are the ones you don’t even notice.
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 asking the company questions if you have any 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.

1. Awara
Best For | An organic mattress with pressure relief
Fiberglass Free Materials | GOLS & FSC certified organic latex, 100% GOTS-certified New Zealand wool, OEKO-TEX certified materials
Features | 365-night trial, lifetime warranty, free shipping

Awara has two cozy organic mattresses we love — their new Natural Luxury Hybrid Mattress and their Premier Luxury Hybrid Mattress are both are fiberglass free. Instead, the brand uses a chemical-free fire retardant option in the form of 100% organic New Zealand wool. In addition to the natural and safe materials, we love the individually-wrapped coils that provide customized contouring 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.
Customer Review | “I purchased a queen size to replace the mattress in my camper. Love this mattress! I get the best sleep when camping and don’t experience back and joint pain after waking up. Going to eventually replace my king size mattress at home with this same one!” – Tammy W. (Read all reviews.)

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.

We’re big Saatva fans when it comes to our home — from comfy pillows to breathable sheets and luxurious bath towels. So it’s no wonder we also love the Saatva mattress collection for organic, fiberglass free bedding solutions. That’s right; Saatva promises the cleanest mattresses to its customers. Rather than fiberglass, the brand uses natural thistle (plant-based fiber made mainly from wood pulp) and organic New Zealand wool as a flame retardant. Likewise, the all-natural Talalay latex is hypoallergenic and resistant to mold, microbes, and dust mites. Every mattress also comes with a lifetime warranty. Yes, please.
