The Doona has passed safety tests as both a car seat and also as a stroller and is the only product to have done so. The system is all integrated so that the wheels fold away underneath the car seat ready to simply flip out when you are ready to leave your car. The handle extends upwards ready to push. When the Doona wheels are folded away then the handle can be used both to carry the infant carrier but also can be extended when on the floor to enable easy rocking of a baby. You leave your baby in the Doona while you flip from stroller to car seat. The Doona is narrow enough to drive down the aisle of an airplane. The attachable changing bag and the smaller parent console bag are great accessories any parent would appreciate. Nowadays most parents are choosing strollers that can adapt to hold their car seats and the Doona rollable car seat is the best solution.
