The white KOYO will express space with office furniture. The LEGMAN height-adjustable legs will be demonstrated not only for tables and desks but also for applications like monitor stands. We will present a proposal-based exhibition under the theme "Changing space through functionality." - A demo unit of a height-adjustable TV lift with a monitor rotation mechanism using LEGMAN height-adjustable legs and a rotating plate This will overturn the conventional concept of office furniture, allowing for flexible changes in space.
