Story
A Ponti and Cassina chair
The sheet places the Principi in the golden age of the partnership between Ponti and Cassina. It credits the chair to a wish, shared by the company and the designer, to try a production model that was innovative for the furniture industry and based on cooperation between designer and manufacturer.
Four colours
Per the sheet, the iconic design is made more modern by four colour choices, white, Vermillion red, Sky blue and black, taken from ceramics that Ponti also designed.
