Casper Sleep Box Spring Foundation for Full Mattress

The Casper full foundation provides excellent support under any mattress and can be assembled in minutes -- no tools required. Older box springs' slats tend to be too far apart, leaving room for a mattress to sag. The Casper foundation's slats are positioned a perfect four inches apart for optimal support. Engineered with solid wood, it has been rigorously tested for durability and proven to stand up to years of sleep.
