The Mattress Protector
Everything-proof your Casper
Our waterproof mattress protector keeps your mattress looking and feeling brand new by guarding against dirt, spills, and normal wear and tear.
Select a size
Air moves through, stains stay out
We engineered our mattress protector with the same waterproof material used in premium outdoor gear. Its microscopic pores are small enough to keep spills out but large enough to let air in, so your mattress stays cool, clean, and comfortable for longer.
Waterproof & breathable
The waterproof layer keeps your Casper clean and dry, while still letting it breathe.
A silent partner
Designed to supplement the Casper, the protector is quiet and doesn't affect the feel or comfort of our sleep surface.
Fits just right
It perfectly hugs your Casper (and any mattress up to 16”) with unique elastic skirting and a 360-degree grip.
