We bought this chair for my office and I liked it so much we purchased another for our home office. The two major pluses for us are the lumbar support of the back and the headrest! The tension of the amount of tilt is adjustable so you can choose to lay back or be straight up. The instructions were straight-forward and a quick easy assembly. We would highly recommend this comfortable office chair!
This was my second Hyken chair the first being used several hours every day these past 7-8 months and still holding up very well. I use these chairs on hardwood/resilient floors and find them comfortable and easy to adjust. I am short on dexterity and strength but did not have difficulty with assembly. It would be nice if the seat came fully assembled like some similar chairs purchased in about 2005 but all in all the Hyken is better than average for the money.
