This Doona Car Seat comes with : Base. How do you describe a Doona? It’s not quite a travel system, it’s not quite a stroller, and it’s a little bit of each. The Doona is an infant car seat with integrated wheels, enabling you to click your car seat out of your car, pop out the wheels, and stroll comfortably to your next destination. It’s a whole new kind of baby mobility! The Doona Infant Car Seat will accommodate even the tiniest infants, starting at 4 pounds, and will hold children weighing up to 35 pounds, or up to 32″ long. The seat itself will weigh about 12 pounds, and will be certified for air travel, making traveling through the airport easier than ever: instead of checking your stroller and carrying your car seat onto the plane, you can simply roll it right on, fold the wheels away, and install it right in the airplane seat!
