From South Korean design studio DesignJoo comes the Giro One, the piece that lets you put your own spin on your shelves, lighting, and side tables. The concept is simple: shelves can be added and their height adjusted by spinning them up or down a central pole, at whose top are fixed two LED lamps. Set a shelf low enough, you've got a side table. Need more space for your library? Add on a few more shelves, and you've got a full, three-way bookshelf.
At TreeHugger, we love furniture that can adjust, transform and multitask, and look cool doing it. The Giro One isn't a great space saver; the downside of the three-way shelves is that to use them, you can't tuck the thing into a corner. And it looks like you can't turn the shelves without changing their height, risking messing up the whole feng shui of the room. But it's still a cool design, which lets you change up the design of your living room without buying new furniture, or even dragging it around.
