I could have used this inflatable dress/chair while walking around in sweltering NYC the other day in dress shoes which kept sticking to my heels and causing painful blisters. It's a dress which inflates (via what looks like vacuum cleaner hoses) so you can sit on it -- until it deflates, telling you it's time to get off your lazy butt and start walking again.

From - you guessed it - we-make-money-not-art, where you can check out further details of this self-sustainable chair.
