I'm changing my review on this mattress. I originally gave it 1 star because I found it to be very firm and uncomfortable. However, after sleeping on it for about a week I either got used to it or broke it in because it seems softer to me now. There is still an odor after several weeks, though. I can smell it whenever I walk into the room. I just purchased a zippered mattress protector so hopefully that will reduce the odor.
