The starting point for the design is a minimalist and timeless bright design. Simplicity. A strong and powerful image. Maximum seating comfort with minimal design. Sustainable use of materials. Materials which are readily available and respected the Earth. A simple but strong construction. And the ability, after transport, mounting the chair fast and simple. All materials used within this draft can easily disassembled and reused in other products. The Birchen Chair is the basic model of this design, made of Birch plywood. A more durable version is the Bamboo Chair, made of a radial bamboo sawed plate. Bamboo grows fast and is abundant. The material has also a warm and contemporary look.
