Frequently Asked Questions
A Sleep Number bed requires a firm flat surface to evenly support the air chambers inside your bed. A traditional box spring does not provide the support required for a Sleep Number mattress. The firm solid surface offered by our Integrated Base, a FlexFit™ Smart Adjustable Base or a platform bed is the ideal surface for your Sleep Number mattress.
