This Butterfly Stool was designed by Sori Yanagi and originally manufactured by Tendo in Japan in 1956. As its name implies, it looks like a butterfly flying through the air. This piece was first introduced at the Yanagi Sori Industrial Design Exhibition, held in Tokyo in 1956. It is very simply made with two pieces of molded plywood connected at the seat with two bolts and one rod of steel as a stay. The manufacturing of this stool has almost become a symbol for the manufacturer Tendo and highlights the Japanese principles of simple, efficient, smooth designs. It is a form that is both modern and timeless, and it has won critical acclaim and prizes and been included in major museum collections, such as the Museum of Modern Art in New York. Labeled “TENDO,” this specific piece was most likely produced around 1980.
