We've had ours for a couple years, and we love, love, love it! Before we got our sleep number bed, I woke up every morning with my back hurting. Even on weekends when I wanted to relax and sleep late, my back hurt so bad I had to get out of bed - I could just lay there and relax. Since we bought the sleep number bed, I have not had any back problems. I like that I can adjust the bed to what is comfortable to me at the time. I can make it more firm when I want to sit up and read. DH likes his mattress more firm than I do so the sleep number allows us both to be comfortable. My only regret is that we waited so long to get it. We will be purchasing my DD one in a couple months.
