Easy to fit and user-friendly. The Sirona SX2 i-Size seat that is rotatable through 360 degrees is readily installed and makes fastening the belt easier. With its reliable safety features and ease of handling, it ensures worry- and stress-free car journeys.

A safe and simple trip right from the start

Within a few seconds, you can put your child in the Sirona SX2 i-Size and turn the seat to the backwards position: this ensures your child is safe and protected as soon as you start your journey together. Thanks to the 360-degree rotation mechanism, you can also switch to the forwards position in a matter of seconds as soon as your child reaches the required size. The improved side impact protection of the car seat activates automatically - one less thing to concern you so that nothing will prevent a relaxed trip with your child.
