The BKF chair was designed in 1938 by architects Bonet, Kurchan and Ferrari-Hardoy, all of whom were committed to modern design. They founded the Austral Group in Argentina.
The BKF armchair is also known as the Butterfly chair, it is an iconic seat that rose to fame thanks to the fact that the architect Edgar Kaufman bought a copy for the permanent collection of the Museum of Modern Art (MOMA) in New York and also acquired another example for the "Waterfall House" designed by Architect Frank Lloyd. It is also in the permanent collection of the Museu del Disseny de Barcelona.
Isst Atelier is the only firm in the world that handcrafts the BKF chair with a loyalty accredited by the Bonet family and by the Museu del Disseny de Barcelona.
BKF has been produced since 1954 Isist Atelier, which takes on the challenge of handcrafting this icon of rationalism, originally designed for industrial production, using very high quality leather with 100% vegetable tanning and a solid rod structure. Each copy is signed and numbered from the workshop. The fidelity of the production is accredited by the family of the architect Antonio Bonet, who gave the original drawings of the chair to Isist Atelier, and by the Museu del Disseny de Barcelona.
The architects Bonet, Kurchan and Ferrari-Hardoy, designers of the Butterfly chair, coincide working in Le Corbusier's studio where they learn about the new rationalist currents that bet on modern design and reject the decorative style. Back in Argentina is when they design the BKF, a name that is formed from the initials of their surnames.
Isist Atelier produces the BKF armchair, by hand, taking care to give the highest quality to the product and with a perfect finish. A design icon since the mid-twentieth century, since it was designed in 1938.
The SOFT leather finish stands for oiled natural leather.
