The Premium mattress protector is a popular choice in Protect-A-Bed's® line of mattress protection products. Premium features a cotton terry towelling surface for superior comfort and excellent absorbancy. In addition, the Premium mattress protector is backed with our exclusive Miracle Membrane®. Miracle Membrane® is waterproof while remaining air vapor porous, and allows body heat to easily pass through. It also serves as a barrier for dust mites and allergens, which provides for healthy, irritant-free sleep. * Waterproof yet air vapor porous - acting the same way as human skin * Effective in preventing bacteria and dust mites from breeding in your pillow and mattress (a major cause of asthma, eczema and rhinitis) * Protects mattresses from stains (accidental spills, perspiration, bodily fluids) * Machine washable on hot, tumble dry on medium * Especially helpful in cases of incontinence * Ultra thin with four-way stretch does not detract from the comfort of the mattress * High Quality Fitted-sheet style * Soft and semi-absorbent
