This was delivered on time and carried in by the UPS guy.  We had it a week before opening it because we had to put the bed together.  It was great fun to open.  It was vacuum sealed and rolled up.  Once the bag was cut you could hear the air being sucked into the bag.  It expanded quickly and after 24 hours it looked like it had never been squished.  This is for our guest room and mostly only small children will be sleeping on it.  I would not recommend it for a teenager or adult for every day use.  My friend has one and said that it develops a "valley" where her son sleeps.... and the edge does tend to collapse when you sit on it.  But for an occasional guest, it is quite comfortable!
