Maxi-Cosi Pria™ All-in-One Convertible Car Seat – Sea Shadow

The Maxi-Cosi Pria All-in-One Convertible Car Seat is a 3-in-1 car seat for every stage: rear-facing car seat (5–40 lb, 19–40 in), forward-facing seat (30–65 lb, 34.4–49 in), and belt-positioning seat (40–100 lb, 43.4–52 in). One-hand height adjustment raises the QuikFit headrest and harness together, and the ReclineFit system adds three positions. Plush infant pillows in ultra-soft padding lift out easily. Fabrics pair PureCosi, made without added fire retardant treatment, with EcoCare recycled fabric, and the machine-washable cover is dryer-safe. A 5-point harness and two removable, dishwasher-safe cup holders finish this infant toddler car seat. Engineered and tested to meet or exceed federal safety standards. Meets federal Side Impact standard. Actual fit may vary; not all children will comfortably fit the full weight and height ranges listed. Designed by Parents, for Parents.
