Definition of Car booster seat

Car booster seat: A car seat for a child who has outgrown both an infant seat and a toddler seat.

The US National Highway Traffic Safety Administration and the American Academy of Pediatrics recommend that:

1. All children 12 and under should ride in the back seat.
2. Children over 40 lbs. up to 80 lbs. should sit in a belt-positioning booster seat with both lap and shoulder belt.
3. The booster seat should face forward.
4. Snug belts: The lap belt should fit low and tight across the lap/upper thigh area of the child and the shoulder belt should fit snug crossing the chest and shoulder (to avoid abdominal injuries).
