It is not what I expected it to be.  However, a mattress is such an individual taste issue that I'm not saying it was bad.  It was not comfortable for me at 5'2", 150 lbs.  I expected the top layer to be firmer and more resilient.  I'm a side sleeper and I just need a bit more loft.
UPDATE:  I tried to sleep on this for several weeks and decided it was too uncomfortable.  I have been trying to return this for over a month now and can't get it picked up.  I'm very unhappy at this point and probably will not buy from Wayfair again as a result.  I hate that but the service this time has been horrible.
