Mezzadro Tractor Stools by Achille Castiglioni for Zanotta, 1970s Italian Design - Seating - Vintage Dimensions: 43.5 x 48 cm, height: 50.5 cm Materials: Steel - Metal - Wood Mezzadro stool designed by A. Castiglioni for Zanotta. Designed by the Castiglioni brothers, the Mezzadro stool for Zanotta transforms a simple tractor seat into an iconic object, revolutionizing the history of design and the Made in Italy label, while paying homage to Italian agricultural prowess. Composed of four simple elements, this metal-sprung seat is, above all, a clear message of freedom in defining domestic space. This piece is attributed to the mentioned designer/maker.
