The seat is characterized by a large and ergonomic three-dimensional wooden backrest, with and without armrest. The concept starts from a research on wood bending which led to the development of an innovative technology, now patented, where industrial design meets craftsmanship. Also innovative is the seat plate, designed to accommodate different types of base and backrest, wich allows the development of infinite configuration possibilities over time. The experience and in-depth knowledge of the materials has allowed Activa to tackle this innovative technology and the combination of different materials in a single project.
