This is a real product from Advance Technology Indonesia intended to simulate the motion your hip makes when you're playing hula hoops. They're selling this as a health device to gain the supposed benefit you get when you play hula hoops while you're sitting down.
Basically what it does is that it wiggles your butt while you sit.
EDIT: Just found out that it's also called the hawaii chair
