I remember watching Sleepless in Seattle when it came out in 1993 and thinking Jonah had the coolest chair I'd ever seen. I've wanted one of those chairs ever since. A couple of years ago, I found an imitation from IKEA. Only downer is that it's kid-size. Oh well, the boys love it. It's a source of hours of spinning entertainment... or at least until they get dizzy.
If you're interested in splurging on the real deal, it's made by inmod. A little pricey, but sooo cool. Who wouldn't want an egg chair?
