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
Cotton and wool mattress protectors, with any waterproof layer clearly identified.
Protecting a mattress does not always require a plastic barrier. Absorbent cotton and water-resistant wool offer alternatives, although neither is automatically waterproof. We avoid PVC and added PFAS treatments and explain any other barrier material so you can choose the level of protection you need.

White Lotus Home Waterproof Cotton Mattress Encasement
ORGANIC COTTONUSA PRODUCTION
Why we recommend it: Two organic cotton knit layers surround a thin TPU plastic barrier for spill protection, with a three-sided zipper enclosing the mattress. Handmade in the USA; the cornstarch-derived film is still a synthetic waterproof layer.

Materials: organic cotton · TPU waterproof film

Soaring Heart Organic Cotton Mattress Protector
GOTSORGANIC COTTON
Why we recommend it: Organic cotton catches sweat and body oils in a washable layer, so routine cleaning does not require washing the mattress itself. The GOTS-certified fabric absorbs moisture rather than forming a waterproof seal.
Materials: organic cotton
$99–$289

Bedecor Cotton-Terry Waterproof Mattress Protector — Queen
COTTON
Why we recommend it: Cotton terry loops form the absorbent surface, with polyurethane plastic beneath to block spills and a polyester skirt for fit. This washable Queen cover fits 9–18-inch mattresses; its cotton claim applies to the face, not the whole protector.

Why we recommend it: For full-mattress spill protection, this washable encasement adds a zippered closure to a polyester cover with a polyurethane barrier.

RestTwill Mixed-Fiber Waterproof Waffle Protector — Twin
ORGANIC COTTON
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

RestTwill Mixed-Fiber Waterproof Waffle Protector — Queen
ORGANIC COTTON
Why we recommend it: An elastic skirt fits mattresses 8–18 inches deep, and TPU waterproofing makes this Queen cover practical for spills. The declared blend is 67% polyester, 12% organic cotton, 12% rayon and 9% TPU, rather than entirely organic cotton.

Woolroom Deluxe Washable Wool Mattress Protector — Queen
ORGANIC COTTONWOOL
Why we recommend it: British wool adds a thin cushioning layer beneath unbleached organic cotton, without polyester filling or a waterproof film. A fitted cotton skirt helps hold it in place. Woolroom discloses a chlorine-based washability treatment, so this is not untreated wool. Assembled in the EU; wash on a gentle wool cycle and line-dry. It will not protect against spills soaking through.
Materials: British wool · organic cotton · elasticated edging

Back Science Kool-Flow Cotton-Surface Mattress Protector — Queen
ORGANIC COTTONUSA PRODUCTION
Why we recommend it: A cotton sleep surface provides light moisture protection without a separate waterproof plastic backing. The stretch fabric helps it follow the mattress, but polyester sides and elastane mean it is not all cotton. Made in the USA. The manufacturer says its Eco Dry finish is free of PFAS; that is not an independently verified test result. Choose it for small spills and perspiration, not full waterproof protection.
Materials: 52% organic cotton · 47% polyester · 1% elastane · Eco Dry water-resistant finish

Comfort Pure Natural Cotton Futon Mattress Cover — Queen, 8-Inch
COTTONUSA PRODUCTION

Choose the correct mattress depth, spot clean as directed, and let both cover and mattress dry fully before storage.
Materials: cotton cover fabric · cotton storage straps · zipper, material unspecified

Kelly Green Washable Wool Puddle Pad

Obasan Organic Cotton Mattress Protector — Twin, 6–8 in. Depth
ORGANIC COTTON
Why we recommend it: A stretchy cotton knit cover takes the everyday wear from body moisture and skin oils and can be removed for machine washing.

Rawganique Homesteadville Waterproof Cotton Mattress Encasement — Twin, 5 in.
ORGANIC COTTONUSA PRODUCTION
Why we recommend it: This zip-around cover protects the mattress on more than just its top surface, with organic cotton knit on both sides of a waterproof membrane.

Made in the USA; match the depth carefully and wash cold, then air-dry.
Materials: organic cotton knit · bio-based TPU waterproof membrane · metal YKK zipper · zipper tape and sewing thread (fiber not disclosed)

Why we recommend it: Wood-derived lyocell supplies the filling beneath a cotton cover, offering a wool-free option without polyester batting.

Sleeping Organic Cotton and Wool Mattress Encasement — Queen, 10-Inch
ORGANIC COTTONWOOL
Why we recommend it: A cotton-and-wool zip cover encloses stacked latex layers on every side, helping keep them aligned and shielded from everyday dust and handling. Sleeping Organic hand-sews it in the USA. The perimeter zipper is acrylic plastic, so this is not a plastic-free cover. The listed Queen version fits a 10-inch build; the mattress is separate, and custom covers are nonreturnable.
Materials: organic cotton and wool shell · acrylic plastic perimeter zipper

Sleeping Organic Cotton Knit Mattress Protector — Queen

Why we recommend it: This USA-made fitted cover puts a substantial organic cotton knit over the mattress without a waterproof film.

The cotton fibers are imported; the perimeter elastic's composition is not specified.
Materials: organic cotton double-knit top and jersey skirt · elastic perimeter (composition unspecified)

St. Dormeir Wool Mattress Protector — Twin
COTTONWOOL
Why we recommend it: Wool quilting and a cotton terry surface absorb everyday perspiration without relying on a waterproof membrane. The terry includes a polyester base for durability, so this is not an all-natural-fiber cover. It is a washable layer for keeping the mattress fresh, not protection against large spills. The 16-inch pocket fits mattresses up to 12 inches deep.
Materials: wool · cotton pile · polyester base · elastic

ORGANIC WOOLUSA PRODUCTION
Why we recommend it: This quarter-inch wool pad adds a washable moisture-resistant layer beneath a fitted sheet without a laminated waterproof backing.
