The USB, which combines modern design with functionality, derives its durability from two vertical supports fixed from floor-to-ceiling or floor-to-wall. With adjustable shelf spacing according to needs and space, it can be used as a completely open shelving system. Additionally, it can transform into an all-in-one working and storage system with the integration of cabinets, drawers, and desk top attachments in its lower sections. Maximizing space efficiency in work and living areas, the USB can also be used as a display-storage unit positioned in front of a wall or as a separator that divides spaces and creates semi-transparent areas.
