Happy with the physical chair.  Was not happy with the delivery on different  days 2 on Friday and 1 on Monday. I was expecting delivery on Wed. the 25th. As I'm a senior and they left it on the door step  I had a very difficult time just toget it in the house.  The setup instructions were  in a black plastic envelope in a side pouch. Almost missed them (found them by schear  chance  No book or paperwork on controls  or warranty
