Maxi-Cosi Pria All-in-One Convertible Car Seat

The Maxi-Cosi Pria All-in-One Convertible Car Seat eliminates the need for multiple purchases across your child's early years. This single seat covers three distinct modes: rear-facing from 5 to 40 lbs, forward-facing from 30 to 65 lbs, and belt-positioning booster from 40 to 100 lbs. That continuous span covers approximately 10 years of use, making it one of the most cost-effective all-in-one solutions available for families seeking a long-term, versatile car seat investment.

Daily usability defines this seat's design. The QuikFit headrest and harness system adjusts both simultaneously with one hand and without rethreading—eliminating the most common source of incorrect harness height as your child grows through multiple size changes. ReclineFit's three recline positions ensure proper fit regardless of your vehicle's rear seat angle. The In and Out harness holders keep straps accessible and out of the way during loading, reducing friction during frequent daily buckle cycles. Machine-washable and dryer-safe EcoCare fabric is made from 100% recycled plastic bottles, while PureCosi fabric options eliminate added fire retardant treatments for families prioritizing cleaner material choices.

Safety and travel flexibility are engineered throughout. The seat meets federal side impact protection standards, installs securely with the 1-click LATCH system, and carries FAA certification for aircraft use. Two removable, dishwasher-safe cup holders add practical convenience for every trip. Removable infant pillow and cushions provide newborn support without requiring harness rethreading during transitions.

Perfect for: Families seeking a single birth-to-booster car seat solution, budget-conscious parents avoiding multiple seat purchases, travelers and frequent flyers needing FAA-certified gear, parents prioritizing sustainable or chemical-free fabric options, households with limited vehicle space.
