A belt-positioning booster seat (BPB) is a type of child safety seat that elevates and positions children so that the vehicle lap and shoulder belt fit them properly. Kids who have outgrown a forward- facing harness seat are not ready for just a seat belt or the front seat yet. Instead, they should transition to a booster seat that enables the adult seat belt to fit properly.
Before transitioning to a booster seat, your child should be:
- 4-8 years old.
- At least 40 pounds
- Up to 4 feet 9 inches tall.
- His or Her lap and shoulder belt should fit snuggly. (The lap belt should fit across the hips and the shoulder belt across the shoulder).
- Your child’s ears should reach the top of their forward-facing seat.
- Your child’s shoulders should be above the top harness slots in their forward-facing seat.
- Your child’s neck should not rest too high on his stomach.
- Your child should be mature enough to sit properly in the booster. Slouching or leaning over or sleeps frequently in the vehicle, he may not be ready for a booster seat.
- Always refer to your specific car seat manufacturer’s instructions (check height and weight limits) and read the vehicle owner’s manual on how to install the car seat using the seat belt or lower anchors and a tether, if available.
- Your child should meet the requirements of your state laws regarding booster seat use.
