I was hesitant at first to give this a good review.  I thought it was too firm.  My wife was the one that wanted a new mattress, I liked our current Sealy, as it was only 8 years old and was pillowtop as well.  Turns out, that super cushy soft pillowtop Sealy was the culprit for killing my back.  The firm support of this mattress is awesome and instead of waking up at 2, 2;30, 3, etc. I sleep till 5 am solid now.
