It can seem like there's never a chair around when you need to take a load off, but what if you could simply carry a chair around with you? That's the LEX bionic chair, an exoskeleton project that just blew through its funding goal on Kickstarter. It doesn't require any batteries or complicated electronics. You can take a seat wherever you want. You just have to be comfortable walking around with bionic legs on your butt.
The designers of LEX say it's as easy to put on as a belt. Although, I'd say it's more like putting on three belts. One strap goes around your waist, and then two more fasten around your thighs. The legs fold up to lay flat until you need to sit down, and then it's a simple matter of pulling them up to unlock before sitting down. The entire contraption weighs about a kilogram (2.2 pounds) and has a maximum load of 120 kilograms (264 pounds).
