This chair is easy to setup. Directions are simple and easy to follow. I'm only giving this chair 3 stars because the seat does not recline with the back of the chair.
I purchased this because it looked similar to my Hyken. i also purchased another Hyken. I have to admit that this chair isn't as comfortable or flexible as the Hyken despite the higher cost. It's a decent chair so far but right away I can notice how this chair isn't as flexible adjustable or comfortable as my Staples Hyken chair. It's comparable but if you want a better chair for the same or lower price range I'd go with a Hyken. I will note on here that the Hyken I purchased isn't as nice as my previous one. The quality is cheaper and the adjustments arent' the same but that's a different review all together.
This chair fits me pretty well. I'm 6'2" and about 200 lb and I have a little room left for the width of the seat and plenty of room to the arm rests. The head rest doesn't go high enough to be very useful unless I am leaning back (my shoulder hit the bottom of the headrest if I sit up straight) but I rarely sit back while working so for me it's a minor issue. It rolls well and adjusts total height arm height lumbar support height and headrest height as needed.
I like the chair's firmness when leaning back and it's got a decent number of adjustments. The seat is a little stiff but I'm getting used to it. Fairly easy to assemble.
