Q: How does the Plus collection of the Sirona Gi i-Size differ from the Comfort collection?

In both versions, the 360° air circulation dissipates heat via ventilation channels to support a comfortable seating temperature. The Plus collection also has mesh inserts that increase air permeability even more.

Q: How long should I use the seat in the rear-facing position?

If your child is older than 15 months and at least 76cm tall, the seat can also be used forward facing. For safety reasons, it is recommended to transport children facing backwards for as long as possible. In this case, this is possible up to 105cm.

Q: When can the seat be used with a newborn insert?

The Sirona Gi i-Size is usually for children at least 61 cm tall, but with an insert, it can be used for children as small as 40 cm. And instead of being used from 3 months, it can be used shortly after birth.

Q: Can I also adjust the seat with one hand?

Yes, for ease of use, both the headrest and the tilt can be adjusted with just one hand. So if your child falls asleep in the seat, you can tilt it back with one hand so that they can still continue dreaming.
