How is that an ultimate Trading chair? @SunTrader A normal Executive Chair like the one I'm sitting on right now would be fair more comfortable and functional than the one in OP.
It looks exotic (the wood, the leather) and is of high quality Make sure the metal parts and rollers are of high quality too. I had quite a few bad experiences; - the metal part broke and I almost knocked my head - the metal bushing (brass material) cracked - piston jam - castor wheels jam (because of hair)
There are only two seats in the world that make one feel powerful: a captains chair at a trading desk front seat in a double decker bus
