Pair of vintage armchairs by Geoffrey Harcourt for Artifort Netherlands 1960s

Very rare set of 2 model 040 lounge chairs. Designed by Geoffrey Harcourt for Artifort in the 1960s. The frame is made from steel and rosewood. The seats were upholstered some years ago with wool fabric (probably by "de ploeg) and are still in good condition. One of the seat cushions has a repaired hole but this invisible because it is on the underside. Very hard to come by model and a set is near to impossible to find. Seat height: 42cm.
