Although its straw-like construction makes it look flimsy, Patrick Jouin's OneShot stool is actually made of a sturdy polymer, unfolding from a rolled-up staff in a matter of seconds. The design has no screws, springs, axles or visible hinges, thanks to an efficient laser manufacturing process that crafts the whole stool from a single piece of material in "one shot."

We like Jouin's stool sample for its easy unfolding (just add gravity), efficient storage (its diameter is less than 5 inches folded up), and cool modern look. Plus stools are just better for your posture, kids. Although it doesn't look like you can buy a OneShot just yet, both MoMA and the Cooper-Hewitt Design Museum in New York grabbed it for their collections, so be patient. — Peter Pachal
