Frequently asked questions
Do I need two separate mattresses for a split setup?
Yes. If you have a split king and you want each side to operate independently, you will need to purchase two Twin XL mattresses. Our king adjustable base comes standard as a split king, so you only need to purchase one frame. Frames can also be synced so they move together.
Can I set up the adjustable base myself?
The Casper adjustable base comes with detailed instructions in the box and can be assembled in about twenty minutes. That said, it is a solid, heavy product, so we’d strongly recommend grabbing a friend to help you with the heavy lifting.
What are the benefits of an adjustable base?
The Casper adjustable base can lift your head, your feet, or both at the same time. Lifting up both means you can enjoy a good book or the TV show you’re binge-watching from bed, but each position comes with its own set of benefits.
