The chair is as described. Seat is firm. Instructions to install the seat back with retention pin is lacking. Sensible adjustments to raise and lower chair. Adjustment for seat tilt is crude. It is quite a chore to assemble but the instructions are straightforward except for the seatback pin.
Nice chair. Went together easily. Just had to remove the arms because my wife types a lot using it and the arms do not adjust low enough. Otherwise an excellent purchase.
