The seat can move back and forth on the main bottom rail, to accommodate multiple size heights and leg lengths. To alter the seat position (when the child isn’t in the seat), you just pop open the quick release lever located under the seat. You then give the QR a couple of spins to loosen it, until the lower clamp plate flops down slightly. You then slide the seat fore and aft aligning the plate and main rail notches (12 available positions), sandwich the plate back together and pop the QR bolt into the notch and tighten the whole thing up. I did find it a bit frustrating using the system on occasion, since the lower plate tended to fall off when it flopped back to far if you didn’t hold it in position.
