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.

If you loved the Original Hybrid you'll love the upgraded Dream. This hybrid mattress features Zoned Support and a Breathe Flex Foam top layer that is ergonomically engineered to provide the right amount of soothing comfort level and bounce — making it an excellent choice for anyone looking for a hybrid memory foam mattress upgrade.

Casper hybrid mattresses are designed to work on a firm, solid surface like our foundation, platform, or adjustable bed frame. Having the correct support ensures the performance and longevity of memory foam mattresses.

For slatted frames, we recommend using bed slats that are flat (not bowed), wooden, and no more than 4 inches apart.

We do! For those who aren’t familiar, a split king basically means the frame comes in two parts. With an adjustable base, the two parts are able to work separately or sync together — so you can use the base with two twin XL mattresses or a single king mattress.

Our Cal king adjustable base is also split, but can only be used with our Cal king sized mattress.

Zone Support™ is engineered to keep your spine in ergonomic alignment by providing support where your body needs it most, with firmer foam under the hips, waist, and lower back. Zoned Support Max™ combines our firmer center foam with a second layer of precisely cut channels to cradle the natural curve of your body while adding support to your hips, waist, and lower back for the ultimate ergonomic relief with our hybrid memory foam design. 

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 and convenience 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.

Foam and hybrid 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.
