There are now many approved brands of booster seats, including Basic Comfort, Britax, Century, Evenflo, Cosco, Graco, Guardian, Fisher-Price, LaRoche, Safeline Mission Control and Jupiter. Some booster seats can accommodate children as heavy as 100 pounds. Whatever seat you choose, always send in that pesky little registration card. New innovations may show problems with your model's design, and you want the manufacturer to be able to find you with recall notices or additional instructions. If you have lost the card, or have a used car seat, call the Auto Safety Hotline to register -- (888) 327-4236.

Be sure that any seat meets Federal Motor Vehicle Safety Standard 213. Children with special health problems may need different restraint systems (information can be obtained from the Special KARS [Kids are Riding Safe] Program of the National Easter Seals Society -- (800) 221-6827).
