The mattress arrived less than a week after ordering.  Came in one heavy box, but was easily maneuvered up my steps.  Took less than 5 minutes to cut off the plastic wrap and unroll.  There is a slight smell, but hardly noticeable.  The instructions state to allow the mattress to settle for 48 hours before sleeping on it.  It has been difficult, but I will finally get to sleep on it tonight.  Feels plush.
