A Sleep Number is a setting between zero and 100 that represents the ideal combination of mattress comfort, firmness and support for your body. A Sleep Number can only be found on a Sleep Number Bed by Select Comfort. Best of all, each side of the Sleep Number bed can be quickly and independently adjusted to the precise comfort level each partner prefers.

Finding your Sleep Number is fast and fun. Just lie down on a Sleep Number bed and use the hand-held remote to electronically adjust the amount of air, until your body feels perfectly cushioned and supported. When you have found your ideal comfort level, the number shown on the digital display is your Sleep Number

All Sleep Number beds include: a 20-Year Limited Warranty, 30-Night In-Home Trial, No Charge Shipping

The air pressure is controlled by a hand-held device about the size of a TV remote controller, connected to an electric air pump. There are four models, $300, $500, $700, and $2,000, so it can be a major investment. But considering how much time we spend sleeping and how important sleep is to health (90% of healing takes place while you sleep), it's worth considering. We've had one for several years and it's certainly the best mattress we've ever had.
