This is surprisingly more comfortable than I expected. The arms adjust up and down as well as the chair height. Easy enough to put together. Might need a 2nd person. In the pic the arms are at the shortest height.
This is comfortable but does not have a tilting back. The only real issue for me is the width of the arm rests. Even at the narrowest setting I find need to spread my arms somewhat to rest comfortably on them. I used some washers to tilt the arm rests inward and that has improved it.
