The allure of a Sleep Number bed is the user's ability to adjust the firmness of the side of the bed he sleeps upon, while the person sleeping on the opposite side of the mattress can do the same. This type of bed is designed to accommodate the comfort of each person sleeping on the mattress. Adjusting the firmness is accomplished via a remote, and it's a simple process if you wish to change the sleep number setting at any time.
Lie on your back on the side of the bed you desire to adjust. If you have a remote that has "L" and "R" buttons for left and right, select the one that corresponds to the side of the bed on which you are lying.
Press and hold the up arrow button to increase the firmness of the side of the bed you are attempting to adjust. Note the increase in the sleep number as you hold the button down. Release the button when you reach the desired amount of firmness.
To increase softness in the bed, press and hold the down arrow button until you reach your desired level of comfort.
Repeat steps 2 and 3 until you find the level of comfort that meets your needs. Release the button and note your personal sleep number for future reference. The number will stay programmed into the remote until you reset it.
