This organic cotton waterproof mattress protector features 100% GOTS-certified organic cotton jersey backed with a recycled polyurethane waterproof membrane. Soft to the touch and unobtrusive under your sheet, it protects your mattress without changing the feel you enjoy. 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.

Built with two layers of soft organic cotton jersey laminated with a TPU coating, it delivers a breathable, no-off-gassing barrier that remains completely waterproof. It guards against allergens, pet dander, and dust mites, while remaining free of vinyl, PVC, VOCs, phthalates, PBDEs, flame retardants, dyes, and other potentially harmful chemicals. The protector is machine washable and dryable and carries GOTS, Fair Trade, and OEKO-TEX certifications, with a five-year limited warranty on production defects; please note shrinkage guidance: pre-wash before first use and expect some shrinkage after multiple washes.
