Finding Comfort & Alignment

Learn how to tell when your spine is aligned and how that impacts your comfort, so you can feel more confident adjusting your Sleep Number® setting or choosing a pillow. 

What comfort and alignment look like

Through the use of DualAir™ technology, the Sleep Number® mattress conforms to your body—and gives you incredible comfort and support.

At your ideal Sleep Number setting your neck and back should be aligned in the same position as when you’re standing.

  • If you sleep on your back, the mattress should “fill in” to support the small of your back.
  • If you sleep on your side, the mattress should “fill in” to support the curves of your side.

Pay attention to how you feel 

How you feel in the morning is an indication of how well you slept. At the right setting, your body will feel relaxed and supported. If your mattress is too firm or too soft you may tense up to compensate for a lack of support. Adjusting the firmness of your mattress can help with that. 

  • If your hips are lower than your shoulders your mattress is probably too soft. Try increasing your setting until you feel the pressure relieve in your hips and knees.
  • If you're tossing and turning or feeling stiff your mattress may be too firm. Try lowering your setting until you feel yourself relax into your mattress. 

Keep in mind, your sleep position affects the air pressure in your bed and your bed may not be as supportive while sleeping in the center of a dual chamber bed or on the edge of the bed. 

Finding your Ideal Sleep Number setting

It's normal for your Sleep Number setting to be different than the one you found in the store, because you may have purchased a different model. Each mattress model offers a different amount of support inside the mattress, so it's best to find your Sleep Number setting on your bed. 

It's also normal for your Sleep Number setting to change over time. DualAir™ Technology allows you and your sleep partner to change your Sleep Number setting whenever you need a different level of support. 

Finding the right pillow

When lying on your bed, your pillow should help your head and neck maintain their alignment, same as if you were standing upright. 


Replace your pillow every 1-2 years or when your pillow has obvious signs of wear and aging. 

Visit a Sleep Number store or take our pillow quiz for help finding the right pillow for you.
