This is one of the coolest modular shelving units I have ever seen and it is eco-friendly made from sustainably-harvested woods or bamboo. The Tetrad Shelving is comprised of various geometric shapes, like the ones in the Nintendo Tetris game. The tetrad shapes allow you to arrange and stack the shelves however you like. They can be attached to each other to create one unit or they can be attached to the wall individually.

Tetrad Shelving is made by Brave Space Design whose slogan is “Made Green in Brooklyn”. The shelving comes in 4 different styles. The Tetrad Mega has a shelf depth of 11 inches. The Tetrad Mini has a shelf depth of 7.5 inches. The Tetrad Flat (pictured at top) has colored metal backings for each piece. The Tetrad Bamboo is a beauty in two-tone (pictured below).

A 10-piece set of Tetrad Flat shelving is available at Brave Space Design for $1315. The Tetrad Bamboo starts at $1730. We found a smaller Tetrad Flat set at Modern Tots for $750 that includes one each of the 5 tetrad shapes.
