How to get
The SX4 Box Spring Foundation is a solid surface foundation designed to stand in for a traditional box spring while giving your mattress a stable, even base. It can be placed directly on your existing bed frame to complete your setup with less guesswork.
Built to pair with a Stearns Foster mattress or the bed you already love, this foundation helps support your sleep surface so it can perform as intended night after night. It is also upholstered to blend in with a wide range of bedroom styles for a clean, finished look.
If you are refreshing your bed or replacing an older box spring, our Sleep Experts® can help you confirm the right foundation for your frame and mattress because we make sleep easy.
