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

The child seats in this category are so-called reboarder, so they are first used backwards. One advantage of this series is that they bring a newborn insert, so they can be used from birth. Later, they can be used forward-facing. 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 360°, which makes it easier to get in and out of the seat and allows the angle of the seat to be adjusted. It also meets higher safety standards. The Sirona Zi Plus brings the same features and differs only in the more robust Plus fabrics, which are double woven and therefore more durable.
