In Case of Emergency, This Guest Chair Pops Out Like a LifeboatS

The Pack Chair is a concept (with five working prototypes in development) by designer François Azambourg. Stored rolled like a tiny sleeping bag, the chair inflates instantly when needed.

But instead of just filling with air, the Pack Chair has a cloth body that inflates with liquid polyurethane. Presumably that polyurethane is not something you can just squeeze out later, so the chair most probably becomes a permanent fixture in your home after its deployment.

Still, if it's strong enough to withstand the force of my pork-fed Midwestern frame, it sure looks more comfortable than a folding chair. [Design Boom via Craziest Gadgets]
