Seating and Safety Restraints • Those with a high back. If, with a backless booster seat, you cannot find a seating position that adequately supports your child's head, a high back booster seat would be a better choice. Either type can be used at any seating position equipped with lap/shoulder belts if your child is over 40 lb. (18 kg). Children and booster seats vary widely in size and shape. Choose a booster that keeps the lap belt low and snug across the hips, never up across the stomach, and lets you adjust the shoulder belt to cross the chest and rest snugly near the center of the shoulder. The drawings below compare the ideal fit (center) to a shoulder belt uncomfortably close to the neck and a shoulder belt that could slip off the shoulder. If the booster seat slides on the vehicle seat, placing a rubberized mesh sold as shelf or carpet liner under the booster seat may improve this condition. 183 2008 Navigator (nav) Owners Guide (post-2002-fmt) USA (fus)
