  • Our take on the Waterproof Mattress Protector - Twin through King

    The Naturepedic Organic Cotton Waterproof Mattress Protector uses a three-layer design: soft GOTS-certified organic cotton flannel on top, organic cotton muslin on the bottom, and an ultra-thin waterproof barrier in the center. It blocks liquids, dust mites, and other allergens while allowing some water vapor to pass through, so it breathes better than vinyl or PVC protectors. The stretch knit fabric is quiet and flexible, making it a good fit for anyone who wants organic materials and a cooler, drier sleep. Compared with common waterproof protectors, it avoids questionable materials like vinyl, PVC, phthalates, and latex, but it costs more and may require more careful laundering.
