When to change your Sleep Number® setting

The ability to adjust the firmness of your mattress whenever you like is one big reason Sleep Number® Smart Sleepers love their bed. As your comfort needs change, your bed can change with you.


Your Sleep Number setting is impacted by your preferences and factors including body weight, sleep position and the volume of air in the mattress while you are in bed. We recommend adjusting your Sleep Number setting if you've experienced any changes that impact the feel of your bed. 

Changes to your weight

The air pressure in your mattress is impacted by the weight on the mattress. Pregnancy, weight loss or weight gain are an important time to change your Sleep Number setting. 

Working out

If you’re sore after an intense workout or a new exercise routine, lower your Sleep Number setting by 5 to 10 for a softer sleep surface.

Injury, illness and surgery

If you're recovering from an injury or surgery or dealing with an illness, we recommend adjusting Sleep Number setting to help relieve new pressure points or other sensitivities in your body. Always talk to your doctor if you are having trouble sleeping.

Children and pets sharing your bed

If you share your bed with your children or pets, make sure your Sleep Number setting accommodates the added weight. Typically, smaller pets (20 lbs. or less) will not impact your Sleep Number setting. Sleep Number bed owners who have children or larger pets sharing their bed often find that lowering their Sleep Number setting by five or ten helps everyone feel a bit more comfortable.

New sleeping position

Changing your sleeping position—from back to side, side to stomach, etc.— can affect your Sleep Number setting.

  • When you sleep on your back your weight is more evenly distributed. If you change from sleeping on your back to your side, you might be more comfortable if you increase your Sleep Number setting.
  • When you sleep on your side, your weight is more concentrated in certain parts of your body. If you change from sleeping on your side to your back, you might be more comfortable if you decrease your Sleep Number setting.

Environmental Factors

Temperature in the room and barometric weather changes may cause changes to the feel of your bed. If the number on your remote or Sleep Number app doesn't match the feel of your bed, this could have been caused by environmental factors. We recommend adjusting your Sleep Number setting to be more comfortable.
