Protect your baby’s crib mattress from spills, leaks, and diaper accidents with our GOTS-certified Organic Waterproof Crib Mattress Protector. Two soft layers of organic cotton surround a thin, breathable polyurethane membrane, made with a corn-derived ingredient, that lets water vapor pass through while holding back liquid long enough for cleanup, without the crinkle of vinyl or PVC covers. It’s OEKO-TEX® STANDARD 100 Class I certified, the product class for baby items; GREENGUARD Gold certified for low chemical emissions; and MADE SAFE® certified nontoxic. It’s made with the same construction as our Organic Waterproof Mattress Protector, whose components were lab-tested for 679 PFAS substances, with none detected. Fitted to stay snug on standard 28" x 52" crib mattresses up to 8" deep, it’s machine-washable and tumble-dries on low. Awarded the Good Housekeeping Quality Seal.
