To see if your seat is affected, you have to check the serial number on your seat. For this, turn your seat upside down. On its bottom side you find a white label with a bar code and "Serial no./ID" beneath it.
If your seat is a BeSafe iZi Go X1, its serial number begins with "ZG". Only seats with a serial number from ZG0247548 till ZG(0)270529 are affected and have to be repaired.
