I had one of the memory foam ones and while it was comfortable most of the time, it holds body heat terribly which was too much of a drawback for me. I ended up with a good pillowtop mattress, and replace it about every five years. I have a bad lower back, the wife has a bad lower as well as her neck and shoulder spinal area and we both do pretty well with it, of course there are always "those" nights when I don't think we could get comfortable in any bed. We can't afford to try one of the Sleep Number beds, if it didn't work out that would be too much money down the tube.
