The Wassily Chair, also known as the Model B3 chair, was designed by Marcel Breuer in 1925-26 while he was the head of the cabinet-making workshop at the Bauhaus, in Dessau, Germany.
After the War years, Gavina picked up the license for the Wassily, along with the Breuer designs previously sold Standard-Möbel, Lengyel & Co., and introduced the more recognized Wassily version that replaced the fabric with black leather straps, though the fabric version was still made available. In 1968 Knoll bought the Gavina Group of Bologna. This brought all of Breuer's design into the Knoll catalog.
The chairs has Gavina's label on the back of the tube below the sit.
