Graco's 4Ever All-in-1 Car Seat gives you 10 years of use with just one car seat. It's comfortable for your child and convenient for you as it transitions from rear-facing infant car seat (4-40 lbs.) to forward-facing 5-point harness seat (20-65 lbs.) to high-back belt-positioning booster (30-100 lbs.) to backless belt-positioning booster (40-120 lbs.). For a proper fit, the Simply Safe Adjust Harness System and 10-position headrest lets you adjust the harness and headrest together, with no rethreading. The 6-position recline keeps your child comfortable, while the InRight LATCH system with one-second attachment makes installation easy. It's the only seat that truly goes from baby to booster!
