With exceptional functionality and aesthetics, the Jest by Tanju Özelgin reflects modular and flexible use as a rack unit. Providing a seamless architectural look with metal skeleton construction, the gesture creates a dynamic effect with the use of modularity. It allows constructing regular, irregular layout plans with compatible wooden boxes for each of the sections that make up the total structure. With these flexible usage features, the gesture is suitable for both private and public spaces. Office librarians can be used on school campuses or any other place needing a sleek bookcase. Thanks to its visual identity, it can be used as a divider panel in places. Metal profiles come in either white or black powder-coated colors. Boxes can be lacquered in the desired color or can be ordered in a veneer. Finally, shelves are in clear glass or painted. There are dual, triple, quadruple, and quadruple modules available.
