Sofa, Pierantonio Bonacina, PALLET SOFA, Piero Lissoni, 2011. Pallet is the first outdoor - indoor sofa collection by Piero Lissoni for Pierantonio Bonacina. The Pallet collection takes inspiration from the shape and the functionality of an everyday-use industrial object. The materic beauty of the wooden slats frame is the leitmotif of the project: naturalness and environmental sustainability. The largeness of the upholstered components establishes a brand new concept for the outdoor sofas. Frame in solid iroko wood, seat and backrest cushions in syntetic canvas and 100 percent cotton canvas, removable.
