How to get
Give your mattress a stronger, steadier base with the Sealy SX Foundation. Designed specifically for Sealy mattresses, it delivers supportive stability that helps your mattress feel more consistent night after night.
Compared to a traditional box spring, the SX Foundation is designed to absorb motion and provide a more supportive platform. That can help reduce the feel of movement across the bed and help prevent mattress sagging over time.
With two height options, it is easy to choose the profile that fits your bedroom setup and the look you want. If you are unsure which foundation height is right for your space, our Mattress Firm Sleep Experts® can help, because we make sleep easy.
