Skeptic turned fan. Several months ago I was on a hunt for a new bed. Sadly, the bed I spent $1000 on a year prior was already losing its comfortability and was already feeling lumpy and causing lots of back pain with many sleepless nights. As a last resort, after comparing prices at all the other mattress stores, I walked into a sleep number store. A bit intimidated at first with all the advanced setups and beds. However, I was quickly greeted by a nice representative to take me through all the options and find out my sleep number. In short, it's been 9 months, no back pain with the adjustable firm/soft settings, less tossing and turning, and waking up feeling refreshed. A bit on the expensive side but these beds will last you several years longer than a standard or high end spring mattress.
