Any Sleep number bed owners here?

The wife and I have tried all sorts of different mattresses to try to find something that works. The Tempurpedic was the most comfortable but they only last a few years before collapsing in the hip area. We are now using a mattress from a company called Reverie. It was kind of pricey, but we are now on 7 years of comfort. They use a unique approach as they are using individual latex "coils". You can change the layout to suit your need. If you find a section of the bed starts getting a little softer in a spot that you sleep in you just move the coils around and no more soft spot. If you want to switch from soft to firm, you just rearrange the coils. It works pretty well. It was definitely worth the price.
