Home of Wool Virgin Wool Mattress Protector — Twin
WOOL
Why we recommend it: Virgin wool adds a washable layer between your sheets and mattress, absorbing moisture while elastic corner straps hold it in place. It is not a waterproof membrane; the maker offers lanolizing guidance for greater water resistance.

Mattress protectors
Kids mattress protectors in cotton and wool with any waterproof layer identified and free of PFAS where possible.
Mattress protectors sit between the child and the mattress for many hours. Waterproof coatings often rely on PFAS. Cotton and wool with identified, lower-concern waterproof layers keep the barrier effective without persistent chemicals.

Utopia Bedding Polyester-Bamboo Viscose Protector — Twin
BAMBOO-DERIVED RAYON
Why we recommend it: A TPU plastic backing makes this fitted Twin cover washable spill protection for mattresses up to 15 inches deep. The textile is 80% polyester and 20% bamboo-derived viscose—a regenerated fiber, not natural bamboo fabric.

Welfibr Organic Cotton Surface Waterproof Protector — Twin
ORGANIC COTTON
Why we recommend it: Organic cotton forms the surface, while TPU plastic blocks spills and a polyester skirt secures the Twin cover. Cotton represents 26% of the declared overall content, so the organic claim does not describe the entire waterproof protector.
Materials: organic cotton · TPU waterproof film · polyester

RestTwill Mixed-Fiber Waterproof Waffle Protector — Twin
ORGANIC COTTONRAYON/VISCOSE
Why we recommend it: A washable TPU barrier adds spill protection beneath a waffle-knit surface. The declared blend is 67% polyester, 12% organic cotton, 12% rayon and 9% TPU, so this Twin protector is not an all-cotton or all-natural choice.
Materials: polyester · organic cotton · TPU waterproof film

Kelly Green Washable Wool Puddle Pad

Why we recommend it: Virgin wool adds water-resistant protection held in place by elastic straps, rather than relying on a waterproof film. The maker uses undyed, unbleached wool; wool-specific washing helps preserve its natural moisture repellency.
