The product is a piece of furniture and a system suitable to display, work and store, indoor and outdoor, using only one constituent, laser-cut and bent metal sheets (steel, corten, aluminum), of 2 and 5 mm thick. The metal sheets fit one inside the other, as a modernized “mortise-and-tenon joint”, and form a discrete freestanding structure resistant and stable. This technique makes the best use of a recyclable raw material, creating a sustainable and smooth manufacturing process: no scrap or wasted components are generated, no glue, no screw, no welding are used. As for the user, the furniture is easy to handle: no tool or mounting accessories facilitates assembly and disassembly, no special maintenance (anti corrosion treatment) is needed, and, when in aluminum, the furniture is light. The system allows versatility and flexibility through dimension, finishing and accessory: up to 240 cm height and to 400 cm width, numerous depths, at least 213 RAL colors (matt and glossy), several raw metal finishes and various fixtures such as drawers, cupboards, and semi shelves. Configurations are endless. Concerning the aesthetic quality, the lines are refined; the volume is neat. Everything is structural: the design sobriety enhances the furniture functionality. In a way, this furniture is a design challenge intending to combine visual lightness and material strength and aiming to draw attention to the content rather than the container.
