this would be easy except i need a swivel chair that has a backrest that leans back, instead of sticking up straight. i broke my chair yesterday. i have another chair but the back rest doesn't lean back. i'm already feeling discomfort in my neck (and im trying to play 2k11 right now

). i dunno what the name of the chair i'm looking for. i tried searching for lean back chair. anyone know what kind of chair i'm looking for?
i have thought about forcing my chair to lean back more by breaking the metal metal support down the middle of the back rest (pushing it backwards so the back rest will lean back more). i dunno how to do that. prolly dont have the tools.
