Found this at a good deal and price im 6'2 and 200 lbs the headrest is too short even at its highest position but i knew that going in. The chair itself is fine and easy to set up but the mesh that you sit on that keeps you raised and pretty much the most important part of the chair broke after 3 months of use. Stay away hopefully they will exchange or send a new mesh base.
Staples had a variety of chairs to choose from. The chair we chose was the Staples Dexley Mesh Task chair in black. It was in our price range and most of all VERY comfortable!!
It seems to be a nice chair. The lock to make the chairback stay straight up allows for a 6" movement backwards which shouldn't happen. It is the "play" in the mechanism.
