Since the 1950s the organically shaped seat shell of the Plastic Arm Chair has been combined with various bases and produced in the millions. In the current polypropylene version the Arm Chair provides even greater seating comfort. PACC (PACC = Pivot Armchair Cast Base on Castors) transforms the Arm Chair into a swiveling, height adjustable office chair. Can be ordered with Soft or Hard glides dependent on the floor you have (we will contact you to confirm which one once we receive your order).
