I love these chairs. I just bought this one for a second office so now I have one at each desk is use! I can spend an 8 hour work day in them without issue. The mesh is very comfortable and the head rest adds a nice touch when you have a minute to kick back!
I'm 6'1" and 200lbs and this unit would be great if I were about 2-3" shorter. However I can feel the head rest with the top of my back and shoulders when sitting properly. Everything else is great though. I may be missing something that would allow me to raise the backrest to position the headrest higher but then I think the lumbar support would be too high... Like I said in the title good for the money.
