SIGLA is a design studio working on design in its broad sense. It has two partners that achieved their experiences in collaborating with important Italian and foreign companies. The different skills and interests that they brought in Sigla enable them to work with flexibility in a wide range of design activities: product design, exhibit design for exhibitions and installations, interior design, and organization of design workshops. Marina Bani graduated in architecture at Politecnico di Milano with a thesis on glass, the material, its history and its new opportunities. She collaborated with important furniture companies on industrial products research development. Marco Penati has been responsible since 1970 for the research and engineering of some most important furniture companies. He has held seminars and workshops in Italy and abroad on research and development of industrial products, materials and technologies.
