This is the Archelis wearable chair. It was designed with surgeons in mind, who spend long hours on their feet poking around in people's bodies and silently judging them for ever jamming that Star Wars action figure up their ass in the first place. But I was out of Sharpies! The joints can lock into place, keeping the wearer standing with minimal muscle involvement. Because if there's one thing I can't stand(!), it's using my muscles. If I had it my way I'd just live the rest of my life as a blob of jelly on the sofa. "What kind of jelly?" K-Y, hands down.
Keep going for a short video demonstration.
Thanks to Douglas: who stays standing the old fashioned way: pretending its a game to see who can last the longest without sitting down. I used to hate that game.
