Booster Seats: How To Properly Install a High Back Booster Seat


I interviewed Kapi’olani Medical Center’s Injury Prevention Specialist, Lisa Dau, about booster seats today. When to move into one, how to install the different types into your car, how to secure your child properly and when it’s time to move out of the booster.


How to Properly Install a High Back Booster Seat


  • High back boosters have belt pathways for the lap belt and the shoulder belt. They also have a head restraint / head rest with wings (usually adjustable so that you can match it to your child’s height) to protect against side impacts and allow the child to rest their head if they are sleeping and still stay in the proper safety position for the seat.
  • Place the high back booster in the center of the seat.
  • Child sits on the booster.
  • The head should be within the wings of the seat.
  • Pull the seat belt through the lap belt pathway, making sure the seat belt goes beneath the arm rests.
  • Buckle in to the right buckle for that seat.
  • The shoulder part of the seat belt will go beneath the arm rest near the buckle and across the center of the chest to the shoulder harness guide near the child’s shoulder.
  • Pull the shoulder part through the guide making sure the seat belt is snug across both the lap and chest of the child.
