For kids under 9 years of age who weigh 40 - 80 lb (18 - 36 kg) or are less than 4’9” (145 cm) tall.
Children who are under nine years of age, who weigh between 40 and 80 lb (18 – 36 kg) or are less than 4'9" (145 cm) tall are safest in a booster seat.
The booster seat helps to position the adult seat belt properly across the child’s body.
An adult seat belt alone does not properly fit a child's body - it rides too high on the belly and neck and can cause serious internal injuries in the event of a crash.
-
A child is 3 ˝ times more likely to suffer a head injury in a crash when just using an adult seat belt than when buckled in a booster seat.
- Booster seats are easily installed and generally low cost.
The manufacturer’s instructions and labels on each booster seat state the specific weight, size and/or age of child that the seat will protect. Some booster seats have upper weight limits of 100 lb (45 kg). Follow the manufacturer’s instructions for your booster seat.
