The Shuffle Chair is an interesting furniture experiment by design engineer Niklas Hagemann. "Inspired by the idea that two telephone-books, when shuffled together, are virtually impossible to pull apart (see Mythbusters), I created a paper chair held together by the friction between individual sheets of recycled paper," he writes.
"With a single paper clip to stop the bottom two pages from unravelling, the chair is held together entirely by the friction between the pages (~500)."
"Sketches showing how the paper slots onto the frame."
"Tests with old newspapers proved the principle, a first frame prototype buckling under load, making the final steel frame, close-up of the pins which were inspired by the way paper slots into a ring-binder."
