This mattress is perfect.  It arrived in an easy to handle box.  The mattress is rolled up inside packed through vaccum suction so easy to manuver into place.  Once the packaging is removed it come to fill size.  Brilliant way to ship.  I was able to take care of everything without assistance.  The mattress is exactly as the specifications and information says.  It is very comfortable.  Probably the best mattress I have bought.  You cannot go wrong in buying this.
