Graco Grows4Me 4-in-1 Car Seat is designed for 10 years of use. It’s comfortable for your child and convenient for you! It transitions from rear-facing harness (5-40 lb), to forward-facing harness (22-65 lb), to highback belt-positioning booster (40-100 lb), to backless belt-positioning booster (40-110 lb). For a proper fit, adjust the harness and headrest together-no rethreading required-using the Simply Safe Adjust Harness System. The 10-position headrest and the 6-position recline keep your child comfortable. It’s the only car seat you’ll ever need!
