How old is your son? How tall and how heavy? What is your budget?

Booster seats do not really have incompatibilities like carseats do because booster seats just sit on the vehicle seat (do not get hooked in), the child sits in the booster and the vehicle lap+shoulderbelt gets buckled around the child.

	Booster Seat A booster seat raises your child up so that the car's lap and shoulder belts fit correctly. The lap belt should fall across the upper thighs. The shoulder belt should go across the middle of the shoulder and chest. A booster seat is used for older children up to about 80 pounds. Some states have passed laws requiring booster seats for children up to age 8 or 80 pounds. Check your state's law.
