Lacquered wooden chairs with fabric, 1970s, set of 4

Set of 4 chairs from the 70s with a white lacquered wooden frame and a circular padded seat in fabric. The circular seat is accompanied by a backrest that follows its curved shape, typical of the space-age aesthetic of the 70s. The sturdy structure of these chairs is still in excellent condition. No restoration work has been carried out and, apparently, they do not require any; even the seats are still in good condition.
