In economics an industrial cluster is a combination of of closely interlinked companies, suppliers and institutions. Padded elements, coloured fabrics and structures are the three components of Cluster, which interconnect to build the first totally custom made seat, to form an overall force that produces imagination. The elements with and without armrests and the seat are cold foamed steel cores. French Tunisian designer Luigi Vittorio Cittadini designed Cluster as part of the Desall-design on demand contest, which counts more than 100,000 professionals registered among architects and designers from more than 200 countries around the world. Cittadini's product was chosen among 424 projects by 350 participants from 126 countries. Luxy accepted the fervent provocation and turned it into reality.
