The Graco® 4Ever® DLX SnugLock® Grow™ 4-in-1 Car Seat gives you 10 years of use with one car seat. The 4-in-1 car seat grows with your child as it transitions from a rear-facing harness (4-40 lb) to forward-facing harness (22-65 lb) to highback belt-positioning booster (40-100 lb) to backless booster (40-120 lb). Our Grow technology allows the backrest to widen as the headrest rises so your growing child has the best fit and comfort at every stage. The No-Rethread Simply Safe Adjust™ Harness System allows you to adjust the height of the headrest and harness in one motion for just the right fit. SnugLock® technology allows for a hassle-free installation in less than one minute using either vehicle seat belt or LATCH. The car seat is Graco® ProtectPlus Engineered™ to help protect in frontal, side, rear, and rollover crashes.
