There are only 2 levers and a knob. The knob controls the lumbar. The lever to right I believe ratchets the seat up and down. The lever near the backrest controls the tilt. There's also a bar under the seat that controls forward and back functions.hmmm I assumed that was the up/down function. wonder how you do move it up down then. I assume the lever is for recline, and I dont see a 3rd lever.
