It took somewhat longer to get the mattress, but it was worth the wait.  I love that it is black, has handles, and easy to take out and place on my bed frame.  The only thing I didn't like was that it was not as firm as I thought it would be, yet it is very comfortable.  The middle of the matters seemed to bunch up like a hill, but over time it's settled down.  I thought maybe I had not given it enough time to take its regular shape, but it no longer does this.
