The Tab Chair 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 makes comfortable and ergonomic seating. 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, sledge and height-adjustable 5-star with castors. The sledge base chair is stackable and available with interlocking connectors.
