The Sealy 12” Medium Memory Foam Mattress with Cool and Clean Cover by Sealy is a very well made mattress. It came in a small box and once the plastic is taken off it needs 24 hours to fully expand. The mattress was comfortable but it does take a couple of nights to get used to. My husband complained of a sore back after the first night but that went away by the next night.  Overall a good mattress.
