'I wanted to create a sense of space,’ says Scarpa of his original design for the Pigreco chair. He chose a triangle as the base of the chair for its ‘dynamic’ nature, and the shape can be found as the supporting structure under the seat. However, he notes, the triangle had an ‘integral defect’ and to ensure the chair’s stability, he played with the concept of a four-legged chair, experimenting with geometry to achieve a piece that consists in intersecting triangular and semi-circular shapes. The defining element of the design are the back ‘sister legs’, as he called them, separated by a narrow gap and united through an ingenious wooden joint, that offers structural strength to the chair. The low backrest is shaped in Scarpa’s words, like a big horn and the semi-circular seat is a flat cushion, upholstered in leather or textile.
