The Tab series is a humanistic response to the various ways we sit in a chair. Created with elegance, creativity and discipline by Alain Berteau, the back has a flex which provides a comfortable and ergonomic seat. The front of the chair is padded and upholstered; the back is a hard shell in lacquer or natural wood finish. The base is available in cantilever, sled and height-adjustable 5-star with castors. The sled base chair is stackable and available with interlocking connectors.
