IN is a family of stools formed by two pairs of objects born from the ideas of encounter and complementarity. Each pair is made of the same number of elements of the same shape and size. The slight misplacement of the composing parts allows the other to join, forming a single item. The union of the elements creates a space that can contain a smaller identical pair. IN is produced locally using sustainable birch plywood, combining both CNC technology and hand finishing. The product has been developed as a flat-pack with self-assembly in mind. That makes the customer become involved in its construction and allows them to fully appreciate its structure.
