The chair is very comfortable and supporting. What I like the most is the mesh. It breaths and allows great air flow to keep you from getting hot and sweaty in the chair.
At 5'6" you would think that the arm height could be lowered enough to allow a touch typist to type comfortably. The lowest height did now work; could not keep arms in correct position for touch typing. Chair is comfortable. Took the arms off and now the chair works for me.
The chair is quite comfortable. My only wish is that it would go downward a little more as I like to be seated slightly below the height of my knees (I'm 5'7")
