You will need the BeSafe iZi Modular i-size roll bar replacement part if you buy a second base station for your modular reboard child seat, as the impact bar is only included in the scope of delivery of the Modular, but not included in the scope of delivery of the base station.

Crash bar for the BeSafe iZi Modular child seat system

The BeSafe iZi Modular roll bar prevents the BeSafe iZi Modular from hitting the backrest in the event of an accident. The bracket is included with the BeSafe iZi Modular Reboard car seat and is not included in your package if you purchase the base alone.
