You won't let just anything into your bed! The Glideaway Fully Encased High Profile Mattress Protector encloses and zips around your mattress to defend it against water, dust, and even nasty bed bugs. The 100% polyester knit fabric is breathable, but also completely waterproof which makes it great for spills, incontinence, or bed-wetting. You'll also sleep with peace of mind knowing that it also serves as an anti-microbial dust mite barrier. Made for high-profile mattresses 14 to 18 inches thick, you can find a protector that fits your specific size bed. Twin, twin XL, full, queen, king, and California king sizes are all available at an affordable price.
