Designed by ITO Design (Germany), G20™ brings harmony between form and function. Cast aluminum and highly tooled nylon bring out delicate edge details and create a sharp profile. Whether you lean back to swipe a tablet, or move forward to review project details, each task requires a different posture. A four-position synchro-tilter control makes seat and tilt adjustments simple, with control levers at fingertip level. G20’s unique lumbar tension system adjusts to pressure and body shape ensuring comfortable back support.
