H.12.1 is an object at the interface of a spatial structure, a big puzzle game and a wooden stool or side table. It is composed of twelve individual pieces with distinct geometry, manufactured from solid wood. Through tinkering and toying with spatial relationships, constructing the chair becomes a puzzle-like experience, traces of which remain visible once it has been assembled. The H.12.1 is available in two sizes, and three types of wood: rich American walnut, balanced European oak and light maple.
