Looks like i missed out on groupon deal with the one with arm rest.
I work in balcony on workbench / bar table. Need ergonomic chair which can go higher than usual.
Better than this and with arm rest:

I have a Herman Miller Setu stool for use at my hobby workbench but they're priced way higher than the one you linked to so not sure if it'd be something that interests you.
