TERRY COTTON MATTRESS ENCASEMENT: This Guardmax Mattress Encasement is made a high quality Terry Cotton. The looped pile on both sides in the weave design makes the mattress encasement extremely soft and plush. The Terry Cotton also is much better at absorbing liquids than regular cotton or polyester. 100% WATERPROOF MATTRESS PROTECTOR: The Guardmax mattress protector does exactly that. It protects your mattress against any and all liquids. Whether it is a drink or urine no liquid spill will penetrate through the TPU laminate membrane. BED BUG PROOF MATTRESS COVER: Many mattress encasements make the claim that they are bed bug proof. Only Guardmax makes that claim and backs it up by being manufactured in an EPA Registered Facility. Our nylon coil zippered encasement is state of the art to ensure nothing gets in or out once the mattress has been sealed shut. ZIPPERED MATTRESS PROTECTOR: The Guardmax Mattress Protector is made with a nylon coil zipper, which will prevent the zipper from trapping or snapping as is the case with other mattress encasements on the market. If there was such a thing as state-of-the-art zippered technology. Guardmax's mattress encasement would be it. It is a zipper made with durability in mind. SIZE AND DEPTH: Guardmax's Terry Cotton Mattress Encasement is soft, comfortable, and hypoallergenic. This mattress protector is waterproof and bed bug proof. The mattress encasement has a strong and durable zipper with an air tight zipper. The Guardmax mattress cover can give your mattress a new look or can protect your mattress from any liquid, stain, or spill.
