The Britax One4Life Convertible Car Seat and Britax Baby Car Mirror for Back Seat bundle keeps your child safe and comfortable in the car from birth through the booster seat years. The One4Life car seat features four configurations, converting from a rear-facing infant car seat holding children 5 to 40 pounds to a high back booster holding children up to 120 pounds. Its ClickTight installation system, steel frame, SafeCell technology, and V-shaped tether provide safety, while the quilted padding, 9 recline positions, and ventilation fabric work together for comfort. The car mirror securely attaches to the vehicle headrest to give a clear, head-to-toe view of your rear-facing baby at any angle. Its shatterproof convex glass, crash test rating, and adjustable straps are designed for safety. With its soft grey frame and sleek look, the mirror complements the modern style of the One4Life car seat. Used together, the Britax One4Life Convertible Car Seat and Britax Baby Car Mirror allow you to transport your child safely and comfortably from infancy through the grade school years.
