What are the advantages of booster car seats?

A booster car seat is designed for a child's safety. Any child under 80 pounds and under 4'8" should be in a booster seat. These seats make sure that the child is secure while in the car and make sure the car seat belt does not strangle them. This is important because when a car suddenly stops and the seat belt automatically tightens you do not want the child to be crushed by its weight in places like the throat.
