This beautiful flat pack stool has just four parts and can be put together in seconds—by simply screwing a plumbing value right through its centre.

The Yodessa stool by Tizumuka has a simple stool top, two sets of legs, and the required screw-in valve. Taken apart, it can be packed into a 680 x 400 x 50mm package—and no tools are required to put it together.

The chair won a Red Dot Concepts award, though there's currently no official word on it going into production. We sure hope it does. [Tizumuka via Design Boom]
