The organic cotton waterproof mattress protector features 100% GOTS-certified organic cotton jersey backed with a recycled polyurethane waterproof membrane. Soft to the touch and barely perceptible under your sheet, it provides dependable waterproof protection without sacrificing comfort. It fits mattresses up to 14 inches deep for Twin, Twin XL, and Full sizes, and up to 18 inches for Queen, King, and Cal King. Split King and Split Cal King options are available for adjustable beds.

Made with two layers of soft organic cotton jersey laminated with a TPU coating, this protector is inert and breathable with no off-gassing, VOCs, or PVC. It guards against allergens, pet dander, and dust mites and is free of vinyl, PVC, phthalates, and other chemicals. It’s machine washable and dryer-friendly, ships in eco-friendly packaging, and carries a 5-year limited warranty on production defects. For split sizes, order two Twin XL protectors for Split King or one Split Cal King protector for Split Cal King; pre-wash before first use to minimize shrinkage, and expect 2–5 wash cycles for the best fit.
