Air Lumbar

Proper lower back support is crucial to a healthy seated posture. With the backrest height set to fit the curvature of your lower back (lumbar region) the Air Lumbar® can be inflated to adjust the firmness of the backrest by pumping air into the lumbar area. To inflate the backrest, press the black rubber bulb with your thumb or fingers until the lumbar area is noticeably firmer. To let the air out, press the black button.
