Sit anywhere with this invisible chair[ Wed, 20 Aug 2014 09:57:17 EDT ]It's like a chair that isn't there, but magically appears whenever you need it. It's called the Chairless Chair and you wear it on your legs like an exoskeleton: when it's not activated, you can walk normally or even run. And then, at the touch of a button, it locks into place and you can sit down on it. Like a chair that is now there.
