This is a full-encasement mattress protector for a king bed, sized 78 by 80 inches, with a zipper that wraps the whole mattress rather than a fitted sheet style cover. The polyester shell is padded, waterproof and machine washable, and it carries OEKO-TEX certification for textile safety. It suits people protecting a mattress from spills, pets, bed bugs or dust mites, or covering an older mattress. Against fitted-sheet protectors it seals all six sides, but it is not breathable like cotton or bamboo covers and the padding is thin, so it will not soften a firm mattress.

Owners of zipper encasements like this generally value the full six-sided protection and easy washing. Common complaints are heat buildup, a plasticky feel and the effort of fitting a king mattress into a zippered shell.
