Arrived well packaged with no damage.  Very little assembly required.  It fit right inside my king size bed frame with no modification needed.  This bed is amazingly comfortable.  0n the firm side but i can walk normally when i get out of bed in the morning unlike my old mattress.   It has under bed led lights, a flashlight right on the remote, numerous presets including zero gravity, which is really cool, and of course massage.  I can't think of anything i don't like about this bed.  My son spent almost three times as much for a lesser quality bed.
