This is absolutely perfect!  It comes in a  medium size , tall, square box.  I thought, uhoh, this is not good.  WELL, was I mistaken. It is really shrunk down, wrapped neatly in light plastic, and when the plastic is opened and unwound, it makes the funniest noise...the mattress pops up and it is truly nice. In my pictures, I had just opened it and it is not fully done. It actually took less than 10 minutes
