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 (22-65 lb) to highback booster (40-100 lb). The anti-rebound bar provides an additional layer of rear-facing safety by limiting rotation of the seat and your child in the event of an impact. The Extend2Fit 4-position extension panel provides up to 5” of extra rear-facing legroom, allowing your child to safely ride rear-facing longer, up to 50 lb. 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. This car seat is Graco ProtectPlus Engineered to help protect in frontal, side, rear, and rollover crashes.
