The Sleep and Beyond organic cotton waterproof mattress protector combines 100% GOTS-certified organic cotton jersey with a recycled polyurethane waterproof membrane. This two-layer construction is soft to the touch, breathable, and designed to feel barely noticeable under your sheet, while providing reliable protection for your mattress. It fits mattresses up to 14" deep for Twin, Twin XL, and Full sizes, and up to 18" for Queen, King, and Cal King, with split options for adjustable beds to suit your setup.
Featuring a breathable, inert TPU waterproof coating between two layers of organic cotton, it offers durable, off-gassing-free protection with no vinyl, PVC, or harmful chemicals. The protector is machine washable, designed to reduce allergens, pet dander, and dust mites, and backed by a 5-year warranty on production defects. For best results, pre-wash before first use and allow a few cycles to reach its ultimate fit and comfort, with sizing up to 2–3 inches larger to accommodate natural cotton shrinkage.
