The term mattress cover can refer to a range of products designed to be placed over a mattress, but it most accurately denotes a product that combines protection with a degree of comfort enhancement. It often serves as a lightweight, removable layer that may offer minimal moisture resistance but primarily focuses on shielding the mattress from dust, dirt, and general abrasion. Unlike a dedicated waterproof protector, a standard mattress cover might be made from a stretchable knit fabric, terry cloth, or a simple poly-cotton blend without an integrated impermeable membrane. Its purpose is to keep the mattress clean and provide a slightly softer feel, and it is usually the layer upon which the fitted sheet is placed. In application, a mattress cover is ideal for situations where liquid spills are a low risk but protection from dust and skin cells is desired. For example, in a guest bedroom that is used infrequently, a mattress cover will prevent dust from settling into the mattress fibers during periods of non-use. It can also be used in conjunction with a waterproof protector for layered defense; the waterproof protector goes on first for liquid security, followed by the mattress cover for comfort, and then the sheet. When choosing a cover, key aspects are fit, fabric breathability, and ease of washing.
