The Graco Extend2Fit Convertible Car Seat is engineered to keep your child safe in frontal, side, rear and rollover crashes. This convertible seat grows with your child from 4-50 lbs while rear-facing (at least 1″ below handle) and 22-65 lbs while forward-facing (up to 49″). The Extend2Fit 4-position adjustable extension panel provides up to 5″ of additional legroom, allowing your child to remain rear-facing longer. The Simply Safe Adjust Harness System allows for one-motion headrest and harness adjustments. Please note, we do not guarantee compatibility.
