The Graco Milestone 3-in-1 Car Seat grows with your child. It’s three seats in one, for comfort at every stage. This 3-in-1 car seat converts from rear-facing harness (5-40 lb) to forward-facing harness (22-65 lb) to highback booster (40-100 lb). Thanks to the no-rethread Simply Safe Adjust Harness System, the harness and headrest adjust together in one motion, to ensure that your child is always properly secured. The 4-position recline keeps your child comfortable, while the InRight LATCH system makes installation easy with a one-second attachment. The seat is Graco ProtectPlus Engineered to help protect your little one in frontal, side, rear, and rollover crashes.
