The trio of designers at Brave Space must really love Tetris. And we absolutely love their video game inspired shelving system, appropriately called the Tetrad Shelving system. Just like the game, the walnut and ash shelves are composed of individual interlocking pieces that combine to make for a shelving space of ultimate visual interest. All wood pieces are certified sustainable by the Forest Stewardship Council (FSC) and the walnut veneer is layered on top of the birch using a non-toxic water-based adhesive for an eco-friendly shelving system. And you know you just have to listen to "Korobeiniki" while assembling the pieces together.
