Booster seats are for older children who have outgrown their forward-facing seats. All children whose weight or height exceeds the forward-facing limit for their car seat should use a belt-positioning booster seat until seat belts fit properly, typically when they have reached 4 feet 9 inches in height and are 8 to 12 years of age.
