The Graco Extend2Fit 3-in-1 Convertible Car Seat is designed to keep your child safer and more comfortable from infancy through the big kid years. With its 3-in-1 design, it transitions from a rear-facing harness (4–50 lbs.) to a forward-facing harness (26.5–65 lbs.) and finally to a highback booster (40–100 lbs.). Its standout feature—the 4-position Extend2Fit extension panel—offers up to 5 inches of extra legroom, making it possible for your child to ride rear-facing longer. Engineered with Graco ProtectPlus safety standards and an easy no-rethread harness system, it provides top-tier protection, comfort, and convenience.
