We’re sure Carolien Laro didn’t design this stool as a prank, but any element of seating that goes spread eagle when someone sits on it, deserves recognition as a prank. You sit on the stool, it spreads a bit to manage your weight, you get up, it springs back to its original shape. Costs € 695 ($900), which makes it way too pricey for a prank thing.
