Booster Seat
Booster Seat
Secure children that weigh greater than 33 lb (15 kg) but are less than 60 in (150 cm) tall in a booster seat or on a booster cushion.
 We recommend that you use a booster seat that combines a cushion with a backrest instead of a booster cushion only. The raised seating position will allow you to position the shoulder strap of the adult seatbelt over the center of your child's shoulder and the lap strap tightly across their hips.
Booster Cushion
WARNING   WARNING:  When using a booster cushion, make sure you adjust the vehicle head restraint on that seating position.

Booster Seat/Cushion
Secure children that weigh greater than 49 lb (22 kg) but are less than 60 in (150 cm) tall on a booster cushion.
