Anyone else experiencing the lumbar adjustment knob digging in the middle of their back while leaning into the seat.
You "could" feel the knob if you leave the lumbar adjustment very loose.
Review the adjustment process.
Pull the knob down to release and allow the knob to turn counterclockwise which releases the support.
Push the knob up and click... and turn ratchet adjustment until the seat is firm and supporting your lumbar area. With it moderately tensioned, there should be an inch or more between seat back and knob. If not, the knob is not engaged and functioning. It takes a bit of force to release and engage the knob.
The lumbar is shown in detail at 2:25
