After owning and using this chair for nearly a year I can't say that I would recommend this chair to anyone. The only reason I leave 2 stars instead of 1 is for the customer service for replacing the seat and seat base as the chair had a slight lean to the right. The plastic and mesh are of passable quality the metal of the seat base is poor quality and easily deforms. The chair is overall uncomfortable. The padding at the front of the seat cuts off circulation it also sits too far forwards so you often end up sitting on the plastic at the back of the seat-pan. The lumbar support is too low and tends to fall even lower as it fails to maintain position. The armrests are decent although a bit too far apart. Go with the Hyken if you must have a cheap chair from this company. I wish I had went that route. I'll probably be looking for something by Steelcase after this.
I've been using this chair for a few weeks and am mostly happy with it. The seat height arm height lumbar support neck support and back tension are all adjustable. The only issue for me is that the seat back is a bit too inclined in its fully upright position and a task chair works better with a more upright seating position. I improvised a fix by inserting a few washers where the seat back attaches to the chair to tilt it forward a bit but its not the ideal solution and its difficult to implement. Overall though not a bad value for the price.
The chair was very easy to assemble and is made of good quality materials. The firm seat and back with support adjustments make it comfortable for sitting hours at a time.
My son wanted this chair to replace the old peeling pleather one he's had for the past 4 years. Apparently this is similar to the ones his school has in one of their meeting rooms (uni) and so far so good. Comfortable ergonomic. Took a bit for him to put together as the last couple of holes didn't line up which was frustrating. Good deal at Staples too!
