Elda Bellone has designed a set of tables designed to stylishly stack on top of one another. The aptly name tABLE is actually two tables, one red and one transparent. The transparent table is the thinner of the two, and is designed to seamlessly sit atop the red table.
The transparent table can be slid off of the red one without affecting the performance of either. This simple design lets you easily double the space of your current table or add another table to the room. A design like this is relatively fresh, as most that can be stacked are meant to do so only for storage purposes. I wouldn't mind seeing a whole line of furniture built around the premise of stacking. The space saving possibilities are endless.
