The Doona is really awesome, very functional, especially for travel and when your baby is so little, sleeps all the time, it makes it easy to just pop out of your car, pop the wheels down and go, vs having to connect a car seat into a stroller (if you’re at Target, the grocery store, etc) but if you’re just looking for a good stroller then the Uppa is great! No storage with the Doona. Kind of apples n oranges since the Doona is a car seat and stroller in one.
