Great mattress. Forms to the body well. I waited a couple of months to write this review due to the fact that at first the mattress is very stiff. This stiffness only lasted a few days to about a week. Once it has a couple of days out of the box, the mattress becomes very comfortable. If you are in the market for high quality low cost mattress, look no further.

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 you are a hot sleeper, 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 type in our collection. It is an all-foam mattress made with Breath Flex Foam, Align Memory Foam, and a Casper Core for those seeking the best affordable memory foam mattress experience. 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, making it the best choice for anyone looking for an inexpensive mattress upgrade.
Casper 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.
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.
