Advanced fabric uniquely constructed for powerful mattress protection without sacrificing breathability and comfort. After the mattress cover is sewn, attach extra interior bindings to cover seams and eliminate stitch holes. This process seals the cover to help prevent bed bugs and dust mites from entering or escaping. Encasements are designed with an exclusive triple-seal closure system including an inner flap, a hook and loop corner seal, and a nylon zipper for additional security coverage. In addition to premium waterproof and stain-resistant protection, each mattress protector boasts soft and breathable knit fabric.
