Why Use a Booster Seat?
A booster seat is typically used after a child has reached the upper weight or height limits recommended by the manufacturer of your current forward facing car seat. Children need booster seats because they are not big enough to properly wear an adult seat belt.
The booster seat “Boosts” a child up so a seat belt designed for an adult can be used on a child in a Booster Seat. This is the reason why both a Lap and Shoulder belt must be used with a booster seat. The booster seat raises a child so the lap portion of the belt will fit over the child’s hips or upper thighs and the shoulder portion will fit across the chest resting on the collar bone.
Always follow the manufacturer’s instructions for installation of a booster seat and be sure to note the age, height and weight limits.
Booster seats typically cover children ages eight (4) through seven (7) years of age with weight ranges that vary based on the type of booster seat used.
This is also the step before a child may begin to use an adult seat belt when the child reaches the age of eight (8) and is approximately four-feet, nine inches (4’ 9”) tall.
High Back and Backless Booster Seats
High back booster seats are useful if the vehicle doesn’t have headrests or if the vehicle has low seat back that don’t offer enough support for a child riding in a backless booster seat.
Backless booster seats can be safely used in vehicles that have headrests and high back seats
