This mattress came quickly. It did not smell bad when opened. We have used it for about 2 weeks. I had a lot of back pain with my spring mattress. I don't have it any more, which is why I bought this bed. It is very supporting and contours to your body. No residual movement from the person you share the bed with or the kids that jump up on it. It was packaged well and is very attractive. I would get another one for one of our other bedrooms at some point.
