Our take on the Zippered Mattress Encasement, Twin XL Size Waterproof Mattress Protector, Absorbent 6-Sided Mattress Cover

A six-sided Twin XL mattress encasement in white, built from soft microfiber over a waterproof TPU membrane. It seals with a zipper plus fabric flaps and a hook-and-loop closure, and fits mattresses up to 12 inches deep. That full wrap-around coverage is more than a fitted protector offers, and it is aimed at spills, sweat and bedwetting. It suits kids' rooms, guest beds and anyone who wants the whole mattress covered rather than just the top.
