Our take on the PlushDeluxe Zippered Cotton Mattress Encasement, Waterproof Mattress Protector for 9-12” Mattresses, Twin XL

The PlushDeluxe Zippered Mattress Encasement is a six-sided waterproof protector for Twin XL mattresses 9 to 12 inches deep. It wraps the whole mattress in cotton terry with a zipper hidden under a flap, and it is made without dyes or additives. It suits people who want full coverage against spills, dust and stains rather than a fitted sheet-style pad. Against fitted protectors it covers the sides and bottom too, but it takes longer to fit and the cotton terry surface is not as smooth as a knit pad.
