wall shelf
No wall plugs and no supports needed: A single board and gravity are enough to stabilize this shelf.
Five shelf boards are lasered out of a large multiplex plate. They are placed horizontally across the plate and held by a steel bracket. When books or other objects are placed on the boards, they press against the wall, thus stabilizing the whole shelf, which casually leans against the wall. Pretty amazing!
The Wall Shelf is 95 centimetres wide, 34 centimetres deep and 208 centimetres high.
A demonstration of good design using very little material.
