“New” means used less than 15 seatings! I believe this chair has all the possible adjustments, except I have not found how to raise/lower the lumbar support. Pictures show all the adjustment levers, knobs, settings, etc. Note arm angle is adjustable (shown with one arm max in, the other max out), adjustable in height (relative to the seat), and removable. Seat adjustments are height, tilt, tilt limiting and tilt tension. Has full lumbar support, both adjustable and removable. The PostureFit adjustment, knob on right works with the tilt limiter to support your natural alignment and provide lower back comfort. The footring height can be adjusted for your feet to rest flat on the footring, based on your leg length. Note also in the photos that the footring raises and lowers with the seat height. As you are comparing these chairs, note the difference in the footrings: the flat ones are only found on the original chairs. The replacement rings are round steel. Personally, my feet arches can really tell a negative difference when resting on a tubular footrest. Aeron Size B is recommended if you weigh between 130 and 230 pounds or your height is between 5 feet 3 inches and 6 feet 5 inches. Seat Height adjusts from 24.75 – 29.25. There is a 6 min 44 sec, 2018 youtube video on the Aeron production production process which shows not only how it’s made but also how all the adjustments work.
