These 9 chairs were designed in 1970 by Rodney Kinsman for Bieffeplast. They were made of curved steel rod and galvanized perforated steel sheet in various colours. The slim, technical line and stackable feature have made it an iconic and often reproduced chair. This original series from the 70s features the brands on all pieces and is made up of 4 white, 2 green and 3 black. It is in very good vintage condition, with few signs of wear and age. This piece has an attribution mark, I am sure that it is completely authentic and take full responsibility for any authenticity issues arising from misattribution
