This bed is like sleeping on a cloud. Or it can be like sleeping on a firm cloud. I like the adjustability involved. If I want a firmer mattress, I only have to adjust it with a little remote control. None of the manual adjustments that are sometimes required to make a bed comfier. I used to have back pain and after I purchased this bed, I found the most comfortable setting for me and have had no complaints since. The mattress is big enough for two to sleep comfortably, or one to have tons of space to mkve around in. I was very pleased with the reasonable price I got it for. I would rcommend this sleep number mattress...but if not this model, at least one. They all seem fairly comparable.
