These are nice, unfortunately you actually have to be a profitable trader to afford one, so no one here would be interested:

Quote from cstfx:
Best type of chair I have found so far for trading is a stiff back, wooden chair. It forces me to sit up straight as opposed to slouching back like you do in those reclining chairs often found at work desks. The only drawback is the viewing angle on a stacked-monitor desk stand. The straightback sitting position also has me paying attention better to what I should be during trading hours.
But that's just me.
