Foldschool, Swiss designer Nicola Enrico Stäubli's new series of DIY cardboard furniture for kids takes cardboard furniture in a much more pointy direction—and the best part about it is that it's free. Three different designs, a stool, chair and rocker, exist on his site as downloads that can be easily printed onto standard paper sizes. He includes hints and instructions on his site as well and nowhere are the Foodschool pieces available for sale; "the process of crafting your own piece of furniture is fundamental to the attitude of foldschool."

Aiming to make good design more accessible (a grant from IKEA helped fund the project), Nicola chose cardboard for its ability to easily form ergonomic curves, sustainability and because it's "lightweight, it has soft and warm properties and the kids can paint on it."

Also on Cool Hunting: Nicola designed the packaging on the Victorinox Urban Survivor series.
