Your mattress is an investment. Treat it like one. The Linenspa Smooth Top Premium Waterproof Mattress Protector keeps spills, sweat, accidents, and liquids from ever reaching your mattress thanks to AquaTight™ technology, a totally waterproof barrier that does its job quietly. That's the part worth saying twice: quietly. The brushed polyester finish is smooth, soft, and completely noiseless, so you get a waterproof mattress cover that protects without the crinkle-every-time-you-move situation. It slides on just like a fitted sheet—flexible enough to fit mattresses up to 14 inches thick—and stays securely in place all night. The breathable fabric lets air move through, so it doesn't trap heat or change the feel of your mattress. You sleep cooler, your mattress stays protected, and you won't even know there's a waterproof cover. When it's time to wash, just toss it in the washer and dry on low heat. Simple! Backed by a 10-year limited warranty. Available in Twin, Twin XL, Full, Full XL, Queen, King, and Cal King.
