If you feel unnerved sitting in a rocking chair because you think you're going to fall off, then this One Leg Stool is definitely not for you. Stools are already unstable enough as it is with four legs, but Andrew Kopp has decided to push things to the limit by eliminated the three extra legs.
The One Leg Stool, despite looking useless at first glance, actually functions. The user only has to situate him or herself in the perfect way in order to use the chair properly.
I'll probably stick to a normal chair since I don't have the patience to balance myself every time I want to sit. That, plus it's easier to have regular chairs than something that looks like a pirate peg leg sitting around in my household.
