The Casper Foundation works like a standard box spring - meaning you can put it on an existing bed frame or platform base. Of course, we recommend pairing your Foundation with Casper's Metal Bed Frame that seamlessly lifts the foundation and mattress off the ground!
Regardless of what you put the foundation on, it adds height and ensures your Casper mattress has the support it needs. If you use another bed frame, check to make sure that it's sized to hold the foundation and able to support the combined weight of the Foundation and Mattress.
