Furniture Design The Once Collection Seating by Kristof De Bock At Dasein Products, they are always looking for an unique approach without compromising in functionality or comfort. In this case a chair and a barstool. These seats are made of a laser-cut metal construction and with cowhide upholstered foam cushions. The metals form a strong single legged chair but split again to become supports for the cushions. The seating cushion is directly fixed on the metal. The backrests are connected by a hinge so that they can adapt to the seated person.
