Brave Space is a Brooklyn-based furniture company that produces sustainable furnishings for the home and office. The designers at Brave Space have developed a style that is playful, modern and functional. Their Tetrad Shelving uses the Tetris-inspired shapes to create modular shelving. With wooden sides and multi-color metal backings, the Tetrad Flat is a lightweight shelving unit giving you endless configurations in your space. Blocks can be attached to one another, to the wall or left free floating for life-sized, living room game play. And no, the bottom line doesn’t disappear when you make that perfect configuration.
