We thought about getting the Sleep Number, but we both like completely different settings - which you would think is ideal except for the fact that if you like to snuggle or sleep holding each other, you end up directly in the middle. The middle part is like a regular mattress, it is a few inches wide and doesn't adjust. Therefore, my side (the soft side) had a pretty dramatic drop off from the middle. It's hard to explain, but try it out in the store. Don't just lie there on your back on your respective sides and be impressed. Really lay down and put your arms around each other like you normally would and see what I mean. Whatever you decide, I hope you are happy with your choice. My DH is still trying to talk me into one!
