Safely ride rear-facing longer! The Graco Extend2Fit 3-in-1 Car Seat offers 3 modes of use to grow with your child from rear-facing harness (4-50 lb) to forward-facing harness (26.5-65 lb) to highback booster (40-100 lb)**. It features a 4-position extension panel that provides up to 5” of extra rear-facing legroom, allowing your child to safely ride rear-facing longer. Children are safer riding rear-facing and should ride rear-facing as long as possible, until they reach the maximum rear-facing height or weight rating for their car seat. With Extend2Fit, the adjustable extension panel and 50 lb rear-facing weight limit allow the seat to grow with your child in rear-facing mode, providing extended rear-facing use. The seat features the No-Rethread Simply Safe Adjust Harness System, which allows you to adjust the height of the headrest and harness in one motion, and InRight LATCH for a one-second LATCH attachment. Harnessing is made easier with fuss-free harness storage pockets that conveniently hold the harness out of the way while you get baby in and out of the car seat.
