With a die-cast aluminum frame and molded laminate seat, this system bench enables a continuous extension of the seat area without leaving any spaces in between. This makes it possible to form flexible, changeable layouts within the installation space. The units are also stackable, and can be used to respond flexibly to varying types of use and quantities of users. The corner pieces, made using the new technology of three-dimensionally molded laminate, represent an exceptionally high level of technical intricacy. A familiar-seeming product that is yet new and unprecedented, this design provides seating comfort, outer visual appeal, and satisfying functionality.
