Arrived promptly the at scheduled time.  We opted to have the "Deliver to room of choice" option and the 3 delivery men were just outstanding...this job required some skillful maneuvering and they came through big time (we did tip each of them for this extra effort).  
We opened it up the next day (easily done) , tried out the mattress (quite comfortable), and closed it back up (no problems).  The casters seem to be of good quality; it was fairly easy to move around on the carpeted floor.
I couldn't be happier with the entire process.  I am one happy lady!
