Designed in 1967 by the Florentine Radical group Archizoom, this was the first sofa without a conventional frame. It is composed of two waves made from a polyurethane block cut into two parts with an S—shaped incision, which can be interlocked and stacked to produce different configurations. The lightness and modular design permit a range of various uses: Superonda can be a sofa, a bed or a chaise longue. Like many of the pieces designed by the Archizoom group, it challenges bourgeois conventions, stimulating the creativity and fantasy of the user. The shiny leatherette cover in the basic colors of white, black and red accentuates the pop image.
