The SmartFit® Conform Back Rest takes seated comfort to a new level. With patented back support technology that works in nearly any type of chair, the SmartFit System allows you to customise the height of the back rest to your personal comfort colour for maximum support and comfort for your spine and lumbar. Ventilated back panels conform to your body type via four independent springs which articulate when you shift your posture. Because the panels are ventilated, the back rest dissipates heat to keep your back cool and dry throughout the working day.
