A drafting chair earns its name at the top of its range, and this one lifts the seat from 21.5 in all the way to 29.5 in, which covers a standard desk at the bottom and a standing desk or counter at the top. Working at that height leaves the feet unsupported, which is why the foot ring matters more than any other feature here: it measures 18 in across, adjusts through its own range from 8 to 15 in, and locks at any point by turning a knob, so the legs are carried at whatever height the seat happens to be set to rather than dangling. The armrests adjust too, moving through 3.5 in at the press of a button, and they sit between 28 and 36 in high with a length of 9.5 in each. Behind the back, an S-shaped backrest of 19.5 by 19.5 in follows the spine through both of its natural curves and carries a lumbar support at the lower one, which is where fatigue accumulates first during long sittings. The back panel is dense mesh for breathability while the seat is high density sponge faced in dirt-resistant PU leather, so the surface that takes the most contact also wipes clean, over a seat 19 in deep. A strong 5-claw base with five rolling wheels keeps the chair stable at full extension and easy to move. Rated capacity is 330 lbs or 150 kg, the chair spans 26 by 26 in and 41 to 49 in tall, and it weighs 25 lbs on the scale. Assembly is needed.
