Making a chair may not seem like a particularly creative task. Most designers use the basic, centuries-old model: a structure with a seat, some sort of back support, and legs.

Does an object need to be functional to count as a chair? Does it need to be easily recognizable as a piece of furniture? Meet the chairs of the future—they may not become part of your parents’ next living room set, but they’re breaking new ground in the world of design.
