During COVID, as remote work became more common, people realized the importance of chairs for work at home. That was a momentum for the development of the FOUR chair. Indeed, a wide variety of office chairs good in design and function already existed before that, but few that fit in the atmosphere of living and dining rooms at home. The elaborate and delicate design of the chair is the result of the collaboration of the four powers: namely, Actus and CondeHouse for development and manufacturing; Jin Kuramoto for design; KOKUYO for technical supervision. Please enjoy the functional chair made of wood, aluminum, and leather that show beautiful aging.
