The Hardoy butterfly chair has been around since 1938, but the design looks as fresh and new today as ever. To order, select a size B cover and then frame color. To buy a replacement cover for a vintage chair, measure your frame to determine the size that will fit best. Our canvas covers are finished with a matching edge, although any color may be ordered. Circa50 is the only supplier of Hardoy BKF chairs with heavyweight canvas and a 1-year warranty. Click swatch for large view. For distribution in Europe, click here.

Our service: The popularity of the BKF spawned millions of copies with exotic names such as Siesta Sitting; Africano; Pampeano... and the Butterfly chair. Our four replacement cover sizes fit most of those chairs, including authentic ones. If your frame does not match up to size A,B,C or D, we will create a perfectly-fitting cover just for you. For instance, if your chair measures 32" across the back but only 26" in front, we will combine our patterns to make a D/B cover to fit your frame. If you chair is larger than size D, ask for our custom extra-wide cover at no additional cost.
Our story: The BKF was developed in 1938 by Jorge Ferrari Hardoy along with Antonio Bonet and Juan Kurchan for an apartment building they designed in Buenos Aires. On July 24, 1940, the chair was shown at the 3rd Salon de Artistas Decoradores exhibition where it was discovered by the Museum of Modern Art. At the request of MoMA design director Edgar Kaufmann Jr., Hardoy sent 3 pre-production chairs to New York. One is in the MoMA collection and one is at the Frank Lloyd Wright house Fallingwater, but no one knows where the third chair went. Naming the BKF as one of the "best efforts of modern chair design," Kaufmann accurately predicted that it would become extremely popular here. Likewise, Hans Knoll recognized its commercial potential and added it to the Knoll line in 1947.
