Frequently asked questions
- What setup do you recommend for the Casper mattress?
We designed the Casper mattress to be versatile, so it can work with all standard foundations. As with all foam beds, you want as much direct support under the mattress as possible. A wooden slatted or platform bed offers the most support.
- Why is the Casper mattress better than its lookalikes?
The engineering behind the Casper mattress goes far beyond aesthetics. Our mattress is the result of intensive research and continuous development by our 30-person San Francisco R&D team, who collectively hold more than 50 patents. Unlike putting a cover over an off-the-shelf construction, our approach allows us to quickly respond to customer feedback and continually enhance our mattress. As a result, the Casper mattress has received high praise from Consumer Reports, was named one of Time magazine’s best inventions, and holds multiple industrial design awards.
