All of our mattresses are specifically designed to sleep cool. We run thermal imaging tests and sweat tests to make sure our mattresses feel nice and breezy throughout the night to keep you comfortable.

If sleeping hot is a challenge for you, Snow Technology is our most advanced solution to nighttime overheating. The combination of HeatDelete™ Bands, Phase Change Material, and cooling Snow Cover keep you comfortably cool from the moment you crawl into bed.

The “One” is the firmest mattress in our collection. It is an all-foam mattress made with Breath Flex Foam, Align Memory Foam, and a Casper Core. The One is firmer than our previous value model, The Casper.

If you loved The Casper, you'll love the upgraded One. This all-in-one sleep solution is slightly firmer but still has the signature Casper feel. The all foam mattress is made with Breath Flex Foam, Align Memory Foam, and a Casper Core

A mattress in a box is a mattress that’s compressed in an air-sealed bag and rolled tight so that it can fit into a box that’s easier to maneuver than a traditional mattress. Allowing you the flexibility of picking your mattress online and having it easily delivered to your door.

When you receive the mattress, all you’ll need to do is pull it out of its packaging, lay it flat on your bed frame or floor, and let it expand.

The mattresses can be slept on almost right away but may take up to 48 hours to expand fully. Our Snow mattresses are primarily made with memory foam and can take up to 72 hours to expand fully.
