Busnelli is being involved for half a century in the production of upholstered furniture signed with the silver brand. The experimental care of the searchers of Centro Studi & Ricerche Busnelli (Study & Research Centre) and the co-operation with professional architects and designers, generated high qualitative and design products which denoted the Company's history. Many of these products, characterized by innovative forms, time-proof materials, versatile structures, have contributed to the design history; Fiocco and Libro, original chairs of 1970, are part of the Permanent Collection at the Museum of Modern Art in New York.
