Not many adjustments (only up and down.) Seat is a little soft and a tiny bit tilted (could be the way I put it together.) I actually find it comfortable but fear it will not last. For $90 I can't complain too much more expensive options were less comfortable.
I am 81 year old woman and I enjoyed putting the chair together by myself. No one was here to help me. Easy read instructions and all the parts fitted correctly. Very comfortable chair.
