You spend 8 hours a night with your face pressed into your bedding.
Do you know what's in it?
The forever chemicals in your bedroom
PFAS — per- and polyfluoroalkyl substances — are a class of over 12,000 synthetic chemicals engineered to repel water, resist stains, and prevent wrinkles. In bedding, they show up in places you'd never think to check:
- Waterproof coatings on mattress protectors
- Stain-resistant treatments on sheets and pillowcases
- Wrinkle-free finishes on cotton and cotton-blend fabrics
- Water-repellent treatments on pillow fills and duvets
They're called "forever chemicals" because they don't break down — not in the environment, not in water treatment, not in landfills. A 2022 study published in Environmental Science & Technology found PFAS in a significant share of consumer textiles tested, including products marketed as stain-resistant or waterproof.
Regulators are responding. The U.S. EPA established its first-ever national drinking water standards for six PFAS compounds in 2024. The European Chemicals Agency has proposed the broadest restriction on PFAS ever attempted, covering all 12,000+ substances. California's AB 1817 banned intentionally added PFAS in most textiles as of January 2025. New York passed similar restrictions.

You check food labels. Why not your bedding?
You read ingredient lists at the grocery store. You research what goes into your skincare. You filter your tap water. You might even know what your mattress is made of.
But the sheets? The pillowcases? The duvet cover you pull up to your chin every night?
Most people never think about it. And most brands don't make it easy to find out. The majority of bedding companies don't test their products for PFAS. Many don't know whether their supply chain introduces these chemicals during manufacturing.
When customers ask, the standard response is: "We comply with all applicable regulations." Which, in the United States, means very little — federal PFAS regulation for textiles is still catching up to the science.
