What is the difference between Sirona Z, Sirona Zi and Sirona Zi Plus?

The child seats in this category are so-called reboarders, so they are initially used rear-facing. One advantage of this series is that they come with a newborn insert and can therefore be used from birth. They can later be used in a forward-facing mode. The Sirona Z is the predecessor of the Sirona Zi and requires an additional base, which is not included in the delivery. The Sirona Zi comes with its own base. This base allows the seat to be rotated through 360°, making it easier to get in and out of the car and to adjust the angle of the seat. It also fulfils higher safety standards. The Sirona Zi Plus has the same features and differs only in the more robust Plus fabrics, which are double-woven and therefore more durable.
