Set of four Dialogo model chairs by Afra and Tobia Scarpa for B&B, produced in the early 70s. The most distinctive feature is the light wood structure with a trestle construction. The crucial aspect is the exposure of the joints and construction details, which are not hidden but become aesthetic and characterizing elements, almost with a Brutalist or industrial aesthetic. The padding consists of a fiberglass shell covered in brown leather (cognac) upholstery. The shape is ergonomic, with a curve that embraces and supports the back.
