DO I NEED TO USE A FOUNDATION OR BOX SPRING WITH THE ADJUSTABLE BASE?

Nope. Foam mattresses like Casper’s really just need a firm, solid base, and our adjustable base definitely does the trick! Though it can be tempting to want to add another piece to ensure your mattress gets the support that it needs, the Casper adjustable base is all that your mattress needs to sleep comfortably for years to come.
