This organic cotton waterproof mattress protector combines 100% GOTS-certified organic cotton jersey with a recycled polyurethane waterproof membrane. The polyurethane barrier provides a durable, waterproof layer that remains soft to the touch and is barely noticeable under your sheet. It fits mattresses up to 14" deep for Twin, Twin XL, and Full sizes, and up to 18" for Queen, King, and Cal King. Split King and Split Cal King options are available for adjustable beds.

Safe and sustainable, the protector uses two layers of soft organic cotton jersey laminated around a TPU coating, offering complete waterproof protection with no off-gassing, VOCs, or PVC. It is breathable and free from vinyl/PVC, phthalates, PBDEs, flame retardants, and other carcinogenic chemicals, and it carries GOTS, Fair Trade, and Oeko-Tex certifications. The TPU layer meets GREENGUARD Gold standards. It is machine washable with a 5-year limited warranty against production defects. For best fit, pre-wash before first use and expect minor shrinkage in organic cotton; if you’re using Split sizes, follow the pairing instructions: order two Twin XL protectors for Split King, or one Split Cal King protector (two protectors, one for each side).
