What a great chair! The cat ruined my old desk chair so I was concerned she'd go after this one ... but nope she leaves it alone. Only complaint is the store put the armrests on backwards had to fix when I got it home but that was fairly easy to do. Overall very very comfortable!
The assembly is easy for most parts. The head rest is a little tricky. When finished the seat is really comfortable. Ergonomically. But pay attention to one common thing of this kind of chairs the plastic is hard it could form some hard edges on the seat and hard support on the side of the head rest.
This chair was great at first and seemed durable. Fast forward a couple of months and the tilt lock no longer worked. Fast forward about a year and it squeaks like no other no matter what I tried to alleviate it. It rocks side to side because some of the wheels have somehow become uneven. Thankfully the mesh is still intact which appears to be an issue with some of the other reviews I've read. I thought spending a little more on what appeared to be a nice budget friendly chair I would get longer use of it. Unfortunately I will have to start shopping for a new chair soon after only a couple of years.
This is a very well made chair that's easy to put together. But...I found the seat (not the back) to be uncomfortable. My suggestion would be to go to a Staples and sit in it before you buy. My solution was to use part of my old chair which has cushion rather than mesh and for me that did the trick. I now love my "hybrid" chair.
