Combining the rational and clean design of the body with a wide choice of frames and finishes, the Tweet Chair range ensures maximum adaptability. The Tweet Work Chair has a polypropylene seat shell with a die-cast aluminium swivel central base with a gas lift. The base comes with 4 spokes on castors or glides. The seat shell is available in a single colour or in a bi-colour with a matte scratch-resistance finish on the front to contrast the glossy finish of the back.
