How it works
Hover over a card, or tap it, to see how it works.
-
Manual Tension Control
Turn the knob under the seat. Turn to + for a firmer rock, − for a softer, easier lean.
-
Seat Slide
Lift the lever at the front and slide the seat in or out. Leave a 2–3 finger gap behind your knees.
-
Back Height
Lift the backrest — it clicks up a notch at a time. Go past the top and it drops back to the bottom.
-
Inflatable Lumbar
Squeeze the pump to inflate the cushion in the backrest for firmer support. Press the release valve to let air out.
