Description

A cleaner, more comfortable sleep environment starts with complete mattress coverage. This National Allergy encasement is crafted from 100% cotton with a tightly woven 2.6-micron structure that supports a hypoallergenic, dust proof design while preserving the natural softness and breathability of cotton. No laminates, no vinyl, no trapped heat. The full 6-sided encasement surrounds your mattress completely and secures with an auto-lock zipper plus an internal fabric flap that helps maintain a consistent dust proof seal. Because the cover contains no waterproof films, it stays flexible and silent, moving easily with your mattress for an uninterrupted night's sleep. This encasement is AAFA and OEKO-TEX Standard 100 certified, providing independent assurance of material quality and textile safety. Reinforced seams enhance durability, and the fully machine-washable design simplifies routine care. King size fits mattresses 12" to 16" deep. Measure for best results. With breathable cotton, a quiet feel, and dependable 6-sided protection, this encasement offers a natural way to keep your mattress cleaner, fresher, and more comfortable.
