Sleep & Beyond Organic Cotton Waterproof Mattress Protector Review

A close look at the current construction, waterproofing, fit, care and warranty claims—without pretending we personally tested it.

Editorial note: This review is based on current manufacturer-published specifications. We have not represented it as hands-on testing.

Quick take

Sleep & Beyond currently lists this protector with two layers of organic cotton jersey and a TPU waterproof layer. The product is designed for waterproof protection across the top and four sides, and the adult sizes are listed for mattresses up to 18 inches deep.

Feature	Published specification
Textile	Two layers of organic cotton jersey
Waterproof layer	TPU
Protection	Top plus four sides
Adult fit	Up to 18-inch pocket depth
Warranty	10 years

The detail that matters most

The cotton and the waterproof layer are not the same material. If you are shopping because you want organic cotton next to the sleeper while still requiring a waterproof barrier, that combination can make sense. If your goal is to eliminate synthetic waterproof membranes entirely, compare a different product type.

Care deserves attention

The merchant warns that medium or high drying heat can damage the TPU lining. That is a useful reminder that the most heat-sensitive component—not the cotton—often sets the care rules for a waterproof protector.

Best fit for

Shoppers who want an organic-cotton textile with waterproof protection.
Mattresses where side protection is useful, not just top-surface protection.
Deeper adult mattresses that need up to an 18-inch fitted pocket.

Compare before buying if

You want a non-waterproof, all-fiber protector.
You prefer a wool-filled design.
You need a zippered encasement rather than a fitted protector.
