A shield booster seat, with the shield in place can be used for children between 30-40 pounds; however, a forward-facing seat with a full harness offers the safest choice.
NHTSA and the American Academy of Pediatrics recommends children over one year and between 20 to 40 pounds be restrained in a forward-facing child safety seat, with a full harness.
With shield removed
With some booster seats, when the shield is removed, the booster seat becomes a belt-positioning booster using the vehicle lap and shoulder belts for restraint.
Never allow a child to sit in the booster seat without the shield while using only the lap belt.
Installing a booster seat
Read the booster seat instructions and your vehicle owner's manual before installing the booster seat.
If the vehicle has only lap belts in the back seat, you may want to consider having shoulder belts installed by a dealer or repair facility. Most vehicle manufacturers offer retrofit shoulder belt kits for this purpose.
