Sleep Safe ZipCover Vinyl Bed Bug, Dust Mite, and Allergen Proof Mattress Encasement / Box Spring Protector /Cal Long Twin 9''

Vinyl encasements are constructed with a reinforced sewn in zipper that is fully sealed and encapsulated for no tear construction. Compare this with all other vinyl encasements that consist of a zipper that is either glued or heat sealed onto the vinyl which results in easy lifting and/or tearing off the zipper from the material. The reinforced seams provide up to 50% greater durability than the low performing economy branded encasements. These premium vinyl encasements have added size variance to ensure an easier fit on large oversized mattress and box springs in contrast to the routinely shortened dimensions offered by inferior economy branded encasements. The encasements are anti-bacterial treated on both sides with Ultra Fresh DM-50 to retard mildew, mold, rot, and fungi.
