The Sancarlo armchair is a treatise on statics, ergonomics, function and geometry. Achille Castiglioni has taken up again the idea of the Sanluca, designed a few decades earlier with his brother Pier Giacomo. The result is the breaking-down of the seat into a series of cushions which curve to each part of the body they have to support. Sancarlo is a reissue of a classic designed by Achille Castiglioni. Both versions, armchair and sofa, are composed of a simple, linear, curved tubular frame, on which a number of upholstered cushions are positioned. A ground-breaking concept when it was first presented, it has now been made even more effective with differentiated foam filling, in which the density varies according to the region of the body to be supported. Full of character, Sancarlo is a veritable icon of 20th-century design.
