I just did this, and there's one thing you also need to remember to do. before you try to take off the back portion of the seat, fold down the armrest, stick your fingers between the seat and the top of the furry backing stuff behind where the armrest was. pull this thing off (it is a piece of cardboard with furry cloth stapled to it, attached to the seat frame with velcro). Now unscrew the two bolts on the largest beam. removing the seat is now much easier on your back ::}
