Chassis is a multi-purpose chair weighing just 11.9 pounds. It works well in conference  rooms, informal meeting areas, cafeterias, showrooms, lobbies, hotels or dining rooms. It consists of two materials that are easy  to recycle. The frame is made of high-performance steel metal,  in graphite black, cement grey, grey-white, flame red or brown-green and is powder coated. The shell is either color-matched  with the frame and made of through-dyed polypropylene (graphite black, cement grey, grey-white) or textile-covered  polypropylene. The plastic glides are suitable for both hard and soft floorings. Chassis versions with polypropylene shells with no covers can be stacked up to four high.
