Your mattress works hard. The least you can do is keep it clean. The Linenspa Premium Encasement Waterproof Mattress Protector wraps your mattress in complete 360-degree protection — top, sides, and bottom — with a secure zippered closure that seals out spills, dust mites, allergens, bed bugs, and whatever else the night throws at it. No half-measures, no exposed sides, no “oops.” The waterproof lining does its job without the noise. You know the kind — that plastic-crinkle soundtrack that follows every time you move. Not here. This protector is smooth, soft, and completely noiseless, so it never gets between you and a good night’s sleep. Getting it on and off is actually simple: slide it on like an envelope, zip it closed, and you’re done. When it’s time to wash, just toss it in the machine on hot and tumble dry low. Fits all standard mattresses up to 12 inches thick. Available in Twin, Twin XL, Full, Full XL, Queen, King, and Cal King. This protector is backed by a 10-year limited warranty. Because a mattress is a real investment, and a waterproof zippered mattress encasement is the smartest way to protect it.
