This fun and flexible furniture is called a polymorphic bench and it has a unique mechanical design that will change shape when someone sits down on it.
An interactive balance board and 119 interconnected sections form the core of the structure. Each section is connected via a pivot and bolt system which lets the bench bend and flex according to each person's unique physical profile. It's supposedly comfortable like a hammock, but made of wood.
You're supposed to sit, lounge, climb, jump, rock, or push the bench. You can even crawl inside, if you're not too claustrophobic. [Polymorphic Bench]
