I got this mattress for my son's Christmas gift, and he was excited!  I noticed some people said that the mattress had an odor for a day or two.  I received the mattress on 1226, but my son did not return from his Christmas vacation until 16.  I asked him about an odor, and he said there was none--very happy with that!  After a few nights sleeping on the mattress, his comment was that he slept great!  I am very happy with the purchase!
