Well the other day my greenday poster fell of the wall and toda yi got around to hanging it back up. But to put it back i had to stand on my chair. While doing this it broke and now when you sit on it, you sit at a angle, so well its going in the in now. So i look around the house and found this ball as a new chair. Heres a pic
I was wonmdering it is bad for your back since there is no back rest or any other bad things about it?
