My boyfriend purchased this for me for Christmas. It's Ahhhhh-mazing! He said it was easy to put together ( foot part to the whole unit). I use it every other day and have tried all the different functions and preset massages, there are 12. It talks to you and you can talk to it. There's a USB outlet to charge your phone and to listen to music through the speakers near your head. It's manually adjustable to your body exactly if the scan is a little off. Looks good, not too big for our house, but dies need clearance to use the zero gravity function. There is even heat for your massage, as well as adjustments for intensity and speed.
