Breathing Chair hides a comfortable seat inside a foam cube

This may look like a weird, foam cube. And it is! But it's also a chair, one of the cleverest I've ever seen.

Look closely: in the middle of the cube, the triangular voids are larger. They're meticulously placed, actually, so that when you sit down it forms to you and makes the shape of a chair. When you stand up, it goes back to being a cube. So awesome.
