Sella is a true icon of the design and work of Achille and Pier Giacomo Castiglioni. Work of art and / or object of common use ... Sella was born from Castiglioni's desire to design a comfortable seat that allows you to sit, but not completely, to move, to stand up and sit back freely ... It is also a "ready-made" created from existing objects, but with a different purpose, a tribute to the work of Marcel Duchamp. Sella is designed starting from a bicycle seat fixed on a pink painted steel axis and a hemispherical cast iron base. It is part of the collections of the largest international museums, but above all it remains an extraordinarily pleasant object!
