When Aeru hosts workshops and events, the shelf rotates flat into the wall to accommodate seating. "The cabinet changes form according to the occasion—it can be used to display products, or it can be used as a desk and bench," states the firm in its description of the concept. "Thus, it allows one to use the shop space freely and flexibly. With this cabinet at its core, this shop reflects the fascination of Japanese craftsmanship."
