Is it safe to use old PFAS-treated fabric couches during pregnancy?
Use caution. Older stain-resistant fabric can add PFAS to house dust.
What's actually in it
Many older couches, carpets, and fabric protectors used PFAS to repel stains, oil, and water. You cannot confirm PFAS by looking at a couch. But older fabric furniture labeled stain-resistant, water-resistant, or treated with a fabric protector deserves caution.
PFAS can move into house dust. During pregnancy, that matters because dust gets on hands, food, floors, and baby gear.
What the research says
A 2026 pilot study in J Expo Sci Environ Epidemiol tested vacuum dust from 20 homes in Rochester, New York. Researchers found 43 PFAS. Some PFAS groups were detected in every sample, and homes with more upholstered furniture had higher levels of some PFAS in dust.
A 2026 study in Environmental Science & Technology measured PFAS in matched maternal serum, cord serum, and placenta samples from 102 mother-infant pairs. All 16 PFAS measured were detected, and the study showed PFAS can cross the placenta.
You do not need to panic-buy a new couch. Lower the dust first. Use a HEPA vacuum, wet-mop floors, wash hands before meals, and use a washable cotton cover if the couch is old or treated. For baby items that touch skin often, choose organic cotton when possible.
