From 1963 to 1966 the architects Afra and Tobia Scarpa collaborated with the Italian company Cassina, designing a series of furniture characterized by the use of solid wood, the study of the joint, and the assembly of the parts with screws. Among these pieces of furniture are the 121 chairs (a model created in 1965) which is probably the most famous and the most desired by collectors and design lovers. The chair was made with various materials and finishes. The 4 chairs for sale have the frame made of plywood and the seat and red leather.
