I chose this model because it was a slimmer fit than others on the Staples floor and it works well for my skinny carcass. So far so good tho its seat is a bit unforgiving compared to my last seat (tho not uncomfortable). Adjustments work well tho I haven't got the back as stiff as I'd like; it leans back ever so slightly. Overall a very good chair for a good price.
Like the all mesh seat back headrest for cool comfort & extended sitting. Somewhat stiff if wanting that kind of support. Adjustment knobs are not the best or easiest to use as compared to other chairs.
