My car is not listed in the car fitting list, how do I know if it will fit?

Doona is certified as a Universal car seat, and as such it fits all cars that can accommodate a new-born car seat. There might still be cars in which the Doona won’t fit (e.g. super compact sports cars) but if the Doona doesn’t fit neither will other car seats probably. The Fitting List on the Doon website does not pertain to the Doona but only to the Isofix base, which is not sold in the US.
