The installation was straightforward. All parts fit nicely together. Adjustment of height and tilt is good. Only issue I have is every so often when you sit down on it the chair sinks and you have re-adjust the height. It's not happening as often as my old chair before ended up replacing the cylinder.
This is a great chair for the price. Extremely comfortable easy to assemble and very straight forward directions. My only complaint is I wish the headrest was height adjustable. At 6' 3" it is basically in between my shoulder blades if sitting up straight.
I got my first one over a year ago and it has held up amazingly well. I like the back support and the fact that it can be adjusted for every height as well as having adjustable arms. My son loved to borrow it so much that he bought one for gaming. I haven’t found anything that I don’t like about it.
This is a wonderful chair - good lumbar support the back tilts back so you can 'rock' and is very comfortable. Unfortunately the head rest protrudes too far forward and gave me a headache so I took the head rest off. Would highly recommend this chair.
