The chair was easy to put together and the arm rests are comfortable, but thats all the good I can say about this chair. Im 53 and find that the back of the chair and the neck rest are very uncomfortable... I consistently end up with a sore neck after only 10 minutes of working because I have to lean back too far to rest my back against the chair while the neck support holds my head forward... and although the chair has a nice foam lower back support, the massaging mechanism in it sticks out and digs into my back. Finally, I think seat is too firm and could be improved.
