It was the first sofa to be designed without a traditional frame, and it was created in 1967 by the Florentine Radical group Archizoom.
It consists of two waves, each created from a block of polyurethane that has been split down the middle with an S-shaped incision, that may be stacked and interlocked to form various shapes.
Due to its portability and adaptable construction, it can serve many purposes: Superonda can double as a couch, bed, or even a lounge chair.
It, like many other Archizoom creations, subverts middle-class norms in order to unleash the user's imagination. The pop aesthetic is emphasized by the glossy leatherette cover's use of white, black, and red.
