Twin Mattress Cover

We built a machine-washable mattress cover to complement the best attributes of our mattresses, from heat dissipation to a snug fit. We topped the waterproof protective film with a soft, comfortable cover to mimic the feel of our mattress. The fitted-sheet style of our mattress protector fits mattresses up to 14 inches and allows for easy removal when you’re ready to wash.

The last thing you want as you’re drifting off to sleep is a mattress protector that crinkles and crunches with the slightest movement. Safeguard your investment and sleep soundly with the GhostProtector, our cooling mattress protector with a completely waterproof barrier and allergen-eliminating technology. Most mattress protectors are made of plastic, with a reputation for overheating during the night. Not ours. The GhostProtector uses a soft knit fabric that wicks moisture away and provides quiet breathability so you stay cool, calm and collected.

Everything-proof your mattress. Keep your mattress looking and feeling brand new by guarding against dirt, spills, and normal wear and tear. The best mattress protectors match utility with comfort. You don’t want anything that squeaks or smells, but you need a quality mattress protector that actually protects you and your bedding. To meet these standards, a waterproof mattress cover should use a material that’s liquid-proof and breathable—like Casper’s thermoplastic sheeting. Additionally, full and fitted coverage is crucial. Unlike a waterproof mattress topper, covers need to guard all exposed surfaces (top, sides, and at least partial bottom). We use a clinging stretch design that never slides or shifts, providing maximum waterproof protection.
