The Sleep Number bed is the only bed that lets you track and optimize your sleep with SleepIQ technology. Sensors work directly with Sleep Number DualAir technology inside the Sleep Number bed to measure your average breathing rate, heart rate and movement to track how you’re sleeping. Every morning, you'll see your SleepIQ score and know how you slept. You can also view comprehensive details of your night, including restful time in bed, goal time in bed, average heart rate, average breathing rate, movement and bed exits. You can view your SleepIQ® score and all of your data at the simple touch of a button via your SLEEP NUMBER remote, smart phone, tablet or PC. As a member if Smiley 360 which you can join at http://h5.sml360.com/-/iil1 i went to my local Sleep Number Store and tested the bed which can be as soft or firm as you would like and my number is 40. I really fell in love with this bed. It is so comfortable and roomy.
Disclaimer: I went to the store to try this bed and for doing so i will be compensated with a pillow.
