Watch our video for a step-by-step assembly guide.

To assemble the Casper foundation, first confirm that you have all the materials you’ll need. The box comes with:

- 4 corner pegs
- 2 (longer) side rails
- 2 (shorter) end rails for the foot and head of the foundation
- Support beam that will run down the middle of the foundation, head to foot orientation. **Please note that Twin & Twin XL sizes have no support beam, Full and Queen have one support beam, and King and CAL King have two support beams.
- 2 rolls of slats
