Editor's Pick: Once your child reaches 40 to 50 lbs (18 to 23 kg), the original 5-point harness car seat starts to feel cramped. This booster seat secures with your vehicle's seat belt, giving your child more room to move around. The backrest is removable, so once they're a bit older, you can use it as a backless booster cushion. The headrest has 6 adjustable positions, so you won't need to replace the seat as your child grows. At about 12 lbs (5.4 kg), it's easy to move between two family cars.
