Vintage armchair R3 by Jacob Ruchti for Branco & Preto

R3 chair was designed in 1952 by Jacob Ruchti for a Brazilian collective Branco & Preto. It was set up by a group of visionary architects in São Paulo in 1952. Production runs were kept small. Instead, emphasis was placed on high-quality workmanship and use of the best Brazilian materials. Their furniture expressed a simplicity and lightness through the use of geometric patterns and lines.
