Furniture Design Minimal Techno Arm Chair by Sebastiaan Van beest This is a prototype arm chair which is constructed from recycled solid steel and repurposed bamboo hardwood flooring. It has a matte black coating with brushed brass screws to hold the hardwood slats in place. Even though the design is delicate, the matte black and brushed brass add a certain sense of robustness. This piece is designed to feel as if it does not take up much space, yet has a very strong presence in any room.
