Hockern is an ‘extreme sport’ using a lightweight stool called the Sporthocker. Also known as ‘extreme sitting’. Apparently, it’s becoming popular across Europe (originated in Germany).
The Cool Commentator reckons it might just be a PR stunt for a seating product… I think it’s combination of the two! As a sport, it seems to have been around for a couple of years (YouTube videos from 2008/2009). The Sporthocker is not brand new either, so I’m not sure why there’s alot of buzz around it all at the moment.
