This clever piece by much acclaimed Japanese designer Naoki Hirakoso has been recently revealed at the Tokyo Designers Week. The Yata Stool, a seemingly simple three-legged item, can do so much more than providing a place to sit. Thanks to the special grooves on the bottom of each leg, Yata can be stacked to create sturdy and elegant storage. It can also be arranged into a bench or a coffee table. And thanks to its star-like shape the stool fits into any corner beautifully. You can also stack these stools by crisscrossing and store them away without using too much space.
