I bought this for my telecommuting home office very comfortable after week 1 Seems sturdier and better ergonomically than the similar model I had purchased previously at Costco.
Chair is comfortable and fine. The assembly specifically the headrest was problematic. The screws were not aligned correctly with the holes. I had to go to my workshop and drag out a vise and they force fit the parts. Someone without the strength and tools might find this difficult to put together.
I've had this chair roughly 2 years and it is literally falling apart and the mesh is torn away from the edges of the seat. I only weigh 160 pounds but use the chair daily. It is a comfortable seat and the best by a mile of Staples' offerings for my needs. I bought a SquareTrade who have made it nearly impossible to get it fixed and Staples won't let me take it to the store. So now I'm stuck with a ripped squeaky creaky chair that likes to fall down on its own. Tightening it up only goes so far and the hydraulic part is starting to fail. It's a poor man's Hermann Miller chair and you get what you pay for. Overall I think 2 years is fair for the price I got it for so I can't be too mad. :)
Chair is light and easy to sit and movein. You can work with support and ease with the adjustibility of head and arm support as wrll as height. And the price can not be beat!
