The bedrock of great sleep
Strong and sturdy
Engineered with solid wood, the foundation has been rigorously tested for durability and proven to stand up to years of sleep.
Perfectly spaced slats
Older box springs’ slats tend to be too far apart, leaving room for a mattress to sag. Our foundation’s slats are positioned a perfect four inches apart for optimal support.
Effortless assembly
It can be easily assembled and disassembled in a matter of minutes — and you don’t need to use any tools.
