Speaking of noodle-stuffing seats (oops, that sounds so pornographic!) , um... anyway... after stuffing the seat bottom, does it actually raise the height at which you sit? I ask this because I'm 6'4", and even with the driver's seat set at it's bottom-most setting, my head is almost touching the headliner. I've got no headroom left. But my seat is really saggy (my car seat!)
