Have any furniture you don’t plan to use with your new bed removed from your bedroom before your delivery. Sleep Number Value mattresses and modular bases ship via UPS with simple assembly instructions. Some re-assembly is required if you plan to move your bed. Check out our easy to follow moving instructions or, if you’d prefer, contact customer service to request disassembly or assembly service before or after moving, service fees apply A Sleep Number® mattress 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 a Sleep Number base, platform furniture or slats no more than 2 inches apart is the ideal surface for your Sleep Number mattress.
