All Sleep Number mattresses feature an air pump and remote control to customize comfort by adding or releasing air. The firmness can be adjusted from 0 to 100 in increments of five.

There are optional upgrades, including a base that elevates the head and foot position on either side, a foot-warming feature, and under-bed lighting.
