Prince Chair

The Prince chair is a 1985 design by Swiss architect Mario Botta, part of his Sesta series. It has a tubular steel frame in a circle-repeat pattern — enameled black mesh — with the seat and back upholstered in black and white leather. Like much of Botta's furniture, it extends his architectural language of strong geometric forms (the circle in particular) into a piece of seating.

It's held in museum collections including SFMOMA, which acquired it in 2010.

Mario Botta (born 1943) is a Swiss architect and designer from Mendrisio, in the Italian-speaking canton of Ticino. He trained in Milan and Venice, and briefly worked with both Le Corbusier and Louis Kahn before establishing his own practice in Lugano in 1970.

He's best known for a distinctive style rooted in geometric massing — often symmetrical brick or stone buildings built from basic forms like cylinders, cubes, and truncated cones, frequently split by a central light-filled slot or atrium.
