If a vehicle seating position has a low seat
backrest or no head restraint, a backless
booster seat may place your child's head, as
measured at the tops of the ears, above the
top of the seat. In this case, move the
backless booster to another seating position
with a higher seat backrest or head restraint
and lap and shoulder belts, or consider using
a high-back booster seat.

• 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 following drawings compare the ideal
fit to a shoulder belt uncomfortably close to
the neck and a shoulder belt that could slip
off the shoulder. The drawings also show
how the lap belt should be low and snug
across the child's hips.
