I tried out many chairs at the Staples store and settled on the Staples Dexley Mesh Task Chair because I like the mesh seating and back as well as the lumbar support. I also liked the adjustable arms. It was on sale so price was also a factor. It was easy to assemble in about 30 minutes using only an allen wrench which was provided. After these first several days and sitting for several hours each day I find the chair quite comfortable (I am 6'3"). I would recommend this chair as an excellent choice in its price category.
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!!
Overall this is a comfortable chair good for working at the desk. I have a smaller frame so the headrest sits a little high for my comfort and it would better if the arm rests could go in a little bit more. Great buy comparable chairs I've seen are much higher.
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.
