CAN I USE A BOX SPRING?
The terms “foundation” and “box spring” are basically interchangeable - but sometimes the items can range in support and materials. With a Casper, you need the mattress to sit on a firm and flat support. If you want to use a box spring for durability or height purposes, we recommend purchasing the Casper foundation to ensure that you have an adequate support set. We spent over a year developing the foundation. It’s designed to perfectly support any Casper mattress. As an added bonus, it’s easy to assemble and it comes with the same 100-night trial.
