Documents What are the advantages of a latched booster seat?

The seat remains in the proper position when the child enters and exits the vehicle. Because a latched booster does not move, there is a more consistent seat belt fit through the duration of occupancy. Latching directly to the seat anchors improves positioning of the booster in most vehicles — there's less room for variance in installation.
