we have both types at the shop the kind with the lower back brace and those without , I prefer the one with as I am taller and bend over more and the back peice makes my back feel better by giving it support , the ones without the shorter guys use, untill there back hurts then they steal mine

, we built one for one of the old timers that details the doorjambs & quarters that has a real high back, he likes it but anyone else sits in it complains that it leans forward (on purpose) and when they lean back they are on there backs :lol $89 is not much to keep your back from hurting ..
