A booster seat (F, G) is designed for children who are about 40 to 60 lbs. ( I 8 to 27 kg) and about four to eight years of age. It's designed to improve the fit of the vehicle's safety belt system. Booster seats with shields use lap-only belts; however, booster seats without shields use lap-shoulder belts. Booster seats can also help a child to see out the window. 1-54
