Experience a soft, protective layer that respects both your mattress and the planet. This organic cotton waterproof mattress protector uses 100% GOTS-certified organic cotton jersey backed by a recycled polyurethane waterproof membrane, delivering a quiet, breathable barrier that remains comfortable under your sheet. 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, with Split King and Split Cal King options for adjustable beds.

Designed with safety and sustainability in mind, the waterproof barrier relies on a inert polyurethane coating that is breathable and free of off-gassing, VOCs, and PVC. The two-layer construction combines soft organic cotton jersey with the TPU coating in between for reliable protection, while remaining free of vinyl/PVC, phthalates, and other hazardous chemicals. It guards against allergens, pet dander, and dust mites, and is machine washable and dryer safe. For best fit, pre-wash before first use to minimize shrinkage; the product is covered by a 5-year limited warranty on production defects, though excessive shrinkage or damage from high-heat drying or bleach is not included.
