This is the European version of the Costela chairs, manufactured under license by Forma, Italy. These so called Costela lounge chairs have rosewood plywood ribbed structure supported by a black painted tubular metal frame with brass feet. The chairs are in fantastic original condition and the seats have been newly upholstered in a nice white woven fabric. The Costela chair was an important design for the Brazilian mid-century modern movement in the 1950s. It became so popular that even outside Brazil there was a lot of requests for it. So, they decided to also produce this chair in Europe which was cheaper than shipping the chairs to Europe.
