The Safety 1st Grow and Go All-in-One Convertible Car Seat and the Safety 1st Grand 2-in-1 Booster Car Seat are the perfect pair to keep your child safe and comfortable through every stage, from infancy to pre-teen. The Grow and Go transitions through rear-facing, forward-facing, and belt-positioning booster modes to accommodate children 5-100 lbs, while the Grand 2-in-1 protects forward-facing children 30-65 lbs with its harness and belt-positioning children 40-100 lbs. Together, they cover all necessary stages. Both seats feature side impact protection and are lightweight and easy to install. The Grow and Go's adjustable harness and headrest can be resized in one step, making it simple to custom fit your growing child. Meanwhile, the Grand's deluxe fabric and removable pillow ensure kids stay cozy. Both seats are designed for extended use to avoid frequent replacements. The Grow and Go takes up minimal space when rear-facing for extra legroom and fits 3 across for multiple kids. Each seat pad is machine washable, with dishwasher-safe cup holders to contain messes. Moving from stage to stage, vehicle to vehicle, these seats will provide a safe, hassle-free ride.
