I have purchased over 10 desk chairs in my life and have never bought one anywhere near this bad. The chair tilts too far back even with the tilt lock in place and with tilt tension all the way up. If you use the backrest like you are supposed to you will sit at a 110 angle if u remove the tilt lock thing. You will sit at a 140-degree angle. The 110 angle is a terrible position and uncomfortable for your neck and back. For the price the quality of the parts is far below what should be expected. I highly discourage anyone to purchase this chair. I am extremely dissatisfied and will never purchase another chair from staples. I would return the chair if it was worth the time to take it apart. I will be buying a new chair from somewhere else.
Love the chair. I replaced the Hyken as its seat base mesh wore out after five years. Even though it was covered under warranty I thought it was time to try a new chair. Compared to the Hyken the Dexley is wider and deeper in the seat base. The arms also sit a bit wider than the Hyken. I'm 5'11" and 200lbs. The Hyken feels a bit tight compared to this now. For someone smaller the Dexley may be too big. The Hyken headrest height seemed to go higher than the Dexley. At the Dexley headrest max height I had to tilt the headrest all the way up to be able to rest my head. The headrest also feels a bit further back than the Hyken. When you lock the back in place the Dexley still has a little give before it stops. The Hyken was a much tighter lock. I like the all-black look of the Dexley compared to the Hyken. The chairs roll pretty much the same way not too free on a hardwood floor but generally stays in place on a level floor. Overall very happy with the chair.
I bought this chair for my new stay at home office. I needed a very good lumbar support and this chair has one. It was very easy to put together. It's comfortable and adjustable including the lumbar.
