The Flexform Wings Sofa, designed by Antonio Citterio in Italy for Flexform, is light, airy and clearly architectonic in character. The Flexform Wings Sofa has a slender metal base raised off the floor covered in leather. The almost invisible legs seem to make it float in the air and the back, a soft geometric parallel-piped, low and deep, is supported by slender metal parts fastened to the rear of the structure.
