This arrived on time and in perfect condition.  All I had to do was unwrap it and let it expand for a couple of days.  Some other reviews have stated thst there was a chemical odor that lasted for awhile, but this one did not have any odor at all.  I have only slept on it one night so far.  It is really firm, which is going to take me some getting used to, my old mattress was a medium pillow top.  I would recommend this to someone that really likes a firm mattress.  The only thing I dont like about it is that the sides mash down quite a bit when you sit up to get out of bed. They do bounce right back up, just wish there was more support around the sides.
