A good chair for long hours of work while sitting in one place. The adjustable height allow me to change position relative to my workspace. I wish the adjustable back had more options that just straight up and recline but other than that it's a great chair.
I purchased this chair for my home office. Chose mainly this chair because it seemed to be the best fit to help with my lower back and the price was not bad either. I sit at my computer for long spans and since I've had this chair it really has supported my lower back. It's also very comfortable. It even tilts back and has adjustable arms. Highly recommended!
The chair is well constructed. I would change three things to make it "perfect" for me. 1) The headrest if attached is not height adjustable. It should be height adjustable. It is too low for my head so I am leaving it off the chair. 2) The seating surface is not expandable toward the front of the chair. I have long legs. Were there to be an adjustment to extend the length of the seat cushion it would make sitting on the chair for an extended period much more comfortable. 3) The instructions call for tightening down the screws every week. I suggest using LockTite or a similar product on the screws after the chair's positions have been optimized so that the screws stay in place.
