Mid-century Hardoy / Butterfly / BKF chairs

A Hardoy chair, also known as a Butterfly chair or BKF chair, is a type of chair that has a simple yet distinctive design. It was created by three Argentine architects - Jorge Ferrari Hardoy, Juan Kurchan, and Antonio Bonet - in 1938. The design consists of a folding metal frame that supports a suspended seat made of leather or canvas. The seat and backrest are designed to give the chair its characteristic shape, which resembles the wings of a butterfly. The chair became popular in the mid-20th century and was featured in many modernist homes and public spaces. It was admired for its lightweight, durable design and its ability to be easily moved and stored.
