Maxi Cosi’s RodiSport 2-in-1 Booster Car Seat is designed to be the last car seat your child needs, with the ability to transform from a traditional booster car seat to a backless booster. That means your not-so-little one can continue to ride protected and comfortably until they’re big enough to sit in the back seat without the extra boost up. The 1-hand headrest adjustment with 7 height positions helps you keep up with growth spurts. Multiple recline positions and Rigid-LATCH system makes for a quick and simple install while keeping the booster seat secured to the vehicle even when unoccupied. The RodiSport’s slim design allows for a 3-across fit in most vehicles for busy carpool days. Made with EcoCare soft, breathable, and 100% recycled fabrics that are machine washable and dryer safe, providing ultimate comfort whether you’re out running errands or on an epic road trip. Vehicle shoulder and lap belt guides make it easier for your big kid to buckle themselves, which gives them a sense of independence and you a bit of freedom. Fits children 40–100 lbs. and 43″–57
