As the chair is only used for short sessions the comfort factor was not critical. Easy to assemble and adjust. Comfort fine for average of 30 minute sessions.
Not many adjustments (only up and down.) Seat is a little soft and a tiny bit tilted (could be the way I put it together.) I actually find it comfortable but fear it will not last. For $90 I can't complain too much more expensive options were less comfortable.
For the price seems like a nice sturdy chair. Easy assembly instructions. Hope it lasts as long as the last chair I bought from staples back in the 1990's. Comfortable easy to adjust and priced right.
