Seating and Safety Restraints • High back booster seats 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. Children and booster seats vary 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. The drawings below also show how the lap belt should be low and snug across the child's hips. 211 2011 F-250/350/450/550 (f23) Owners Guide, 4th Printing USA (fus)
