This chair is so worth it. It was easy to assemble. Parts separated in different packaging. # rd. Clear directions with pictures. Allen head tool enclosed. Chair is adjustable. Buy this chair!
At the tilt-lock position the chair back leans entirely too far back and exacerbates my back pain. If you like to sit up and have good ergonomic back support look elsewhere.
The chair is excellent.....best I've every had. It's so much better for my aching back and the headrest is a nice touch to relax the neck muscles on and off throughout the day. The sales rep is super....helped me find a better price on line than what was in the store.
If you spend hours sitting at your desk this chair is a MUST HAVE. Very comfortable and the perfect about of support. If you're comfortable you will be more productive.
