Belt Positioning Booster Seats


Updated September 30, 2012

Definition: Belt Positioning Booster Seats

Boosts child up providing a higher sitting height, which allows the adult lap and shoulder belt to fit properly

Used Forward-Facing Only

  • Kids should sit in a booster seat until they are "old enough and large enough" for seat belts to protect them properly, which usually isn't until they are 4 feet 9 inches tall (57 inches) and are between 8 and 12 years old.
  • According to the latest car seat guidelines, kids can move to a belt-positioning booster seat when they reach the weight and height harness strap limits of their forward-facing car seat.
  • Can only be used with the adult lap and shoulder belt. Never with a lap belt only.
  • Provides the child a higher sitting height, which allows the adult lap and shoulder belt to fit properly.
  • The shoulder belt should cross the chest, resting snugly on the shoulder, and the lap belt should rest low across the upper thighs. Never up high across the stomach.
  • Styles include high-back, no back, and base only. A high-back booster provides head support not provided by vehicle seats with low backs or no head restraints.
  • The mid-point of the back of the child’s head (ear level) should not be above the vehicle seat back cushion or the back of the high back booster.
