GOTS certified organic cotton mattress protector with waterproof protection — no vinyl, PVC, phthalates, or butane rubber. Soft, quiet, and breathable, with a fitted skirt that works on mattresses from 9" to 16" deep. How It Works Three layers: GOTS certified organic cotton jersey on top and bottom, with an ultra-thin TPU polyurethane barrier in the center. The barrier blocks liquids while allowing water vapor to pass through — Naturepedic's proprietary DrySleep™ Technology. The result is waterproof protection that doesn't trap heat or cause the sweaty, clammy feeling common with conventional protectors. The stretch-knit fabric is soft, flexible, and completely silent — no crinkling. Beyond liquid protection, the protector acts as a barrier against dust mites and pet dander, keeping your mattress surface cleaner without relying on chemical treatments.
