Avocado Organic Waterproof Mattress Protector review

Avocado's protector is the pick for people who care most about materials. Two layers of GOTS-certified organic cotton surround a thin polyurethane membrane made with a corn-derived ingredient, and the waterproof layer is only about 5% of the protector by weight. Avocado says independent labs tested every component for 679 PFAS substances and found none, and the protector carries GREENGUARD Gold, MADE SAFE and OEKO-TEX STANDARD 100 certifications. There are no fire retardants or antimicrobial treatments. The Standard Pocket fits mattresses 6 to 16 inches deep and the Deep Pocket up to 22 inches. Avocado is unusually candid about limits: the membrane holds back spills, sweat and occasional accidents long enough to clean up, but it is not meant for heavy or prolonged liquid exposure, and its performance can fade with washing. It cost $135 on sale against a $169 list price when we checked, with a 100-night trial and a 1-year warranty.
