We cannot seem to get our RF middle seat Chicco Nextfit to not move less than an inch side to side at the back of the catseat. Using LATCH, at the belt path there is no movement, but there is 1 to 3 inches of movement at the back of the carseat (closest to the front seat of the car). We have the Graco Headwise next to the seat (at a window).
What should we do to reduce this lateral movement at the back of the carseat?
