There is a key fatal flaw to this chair (for me). If you want it free to lean backwards you must set it at the "neutral" setting. This causes the chair to lean slightly forward (not enough leg/thigh support?). There's no way to adjust the angle of the chair while also allowing it to lean backwards. I wouldn't recommend this chair to anyone.
The chair is comfortable and easy to manipulate. I would recommend it to friends and relatives who were looking to make such a purchase. It was given to me as a gift.
