We purchased this mattress because of all the talk on how great it is for your back.  Well not my back!  Let me warn you that if you have back pain in your middle back, on the outer curve of your back, do not buy this kind of mattress.  It puts too much pressure on that part of your back and it becomes very uncomfortable.  This foam mattress is way to firm.  When you press on the foam it looks as though it is soft and you will just sink into it. However, in reality, when you lay down on it, your weight is distributed out through your entire body and you don't sink in much at all.
