The i-Size, or regulation R129, is a car seat legislation that uses a new way of testing seats for infants and children, including a new side impact test. i-Size seats are chosen based on the child's height, ensuring the correct size for the seat. They are considered the safest, with improved head and neck protection.

• The results of side impact crash tests are evaluated under the i-Size standard.
• Some i-Size car seats allow rearward-facing use until the child is 105 cm tall, approximately four years old.
• Using a rearward-facing car seat can provide up to 75% greater protection in the event of a car accident.
