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 Mattress Protector

Waterproof & breathable

The waterproof layer keeps your Casper clean and dry, while still letting it breathe.

Silent Mattress Protector

A silent partner

Designed to supplement the Casper, the protector is quiet and doesn't affect the feel or comfort of our sleep surface.

Firts Just Right Mattress Protector

Fits just right

It perfectly hugs your Casper (and any mattress up to 16”) with unique elastic skirting and a 360-degree grip.
