Protect your dorm mattress with a durable, fully zippered encasement designed to create a clean and comfortable sleeping surface. Made from heavyweight waterproof vinyl, it surrounds the entire mattress and features electronically sealed seams, a patented BugStop seal, and a self-locking, rust-resistant polyester zipper. An antimicrobial treatment helps slow the growth of mould, mildew, and fungi, while the encasement also provides protection from dust allergens. It has been independently tested and certified as bedbug-proof and is treated for flame resistance.
