What Maxi-Cosi says
The Maxi-Cosi Petra All-in-One Convertible Car Seat is designed to be there for all of life’s adventures. Created to grow with your child from their very first journey home through the elementary school years, Petra brings together long-lasting comfort, trusted safety and protection, and thoughtful design—so you can focus on the moments that matter most. The Petra 3 in 1 car seat is crafted with PureCosi™ fabrics made without added fire retardant treatments, paired with EcoCare, our premium, 100% recycled fabric made from plastic bottles. The result is soft, breathable, and beautifully refined. Installation is fast and easy thanks to 1 click LATCH connectors, designed to help ensure a secure attachment with minimal effort. As your child grows, features such as a 3 position adjustable base and a QuikFit one hand adjustable 8-position headrest and harness system make transitions simple and intuitive. The Petra All-in-One Car Seat for babies, toddlers, and big kids is designed to adapt through every stage from 5 to 100 lbs. with 3 modes of use: rear facing infant car seat (5–40 lbs. and 19”–40”), forward facing toddler car seat (30–65 lbs. and 34.4”–49”), and belt positioning booster car seat for big kids (40–100 lbs. and 43.4”–52”). Actual fit may vary. Not all children will comfortably fit in the seat for the full weight and height ranges listed. Proudly made in Columbus, Indiana.
