This is a high quality mattress and we have been so impressed.  We previously had a mattress that came in a box and felt like you were sleeping on an air mattress.  This mattress is so solid and feels very well made.  I will say, the firmness is a bit too much, so we did end up buying a topper for it, but overall we love it. I definitely notice less back/neck pain than what I experienced on our old mattress.
