This is Casper's waterproof mattress protector, a fitted cover that shields the mattress from spills, sweat and accidents while keeping the mattress's own feel. It fits mattresses up to 16 inches deep, so it works with most standard and pillow-top beds, not just Casper's. The waterproof layer is the main draw: it protects the warranty and the mattress without the crinkle and heat of a cheap vinyl cover. Owners rate it well overall, though some find it warmer than expected and a few say it runs snug on thicker mattresses.
