i-Size, or Regulation R129, is a car seat legislation that uses a new way of crash-testing car seats for babies and children, including a new side-impact test. i-Size seats are chosen based on the height of a child to ensure a child is the correct size for the seat.

i-Size car seats are considered to be the safest, with improved head and neck protection. That's because: 

Side-impact crash test results are assessed as part of the i-Size standard. 

i-Size safety tests are completed using advanced Q-dummies, which have more sensors than the dummies used for the R44 test.  

Your baby must travel in the very safe rear-facing position up to the minimum recommended age of 15 months. Some i-Size car seats can even be used rear-facing until your child is 105 cm tall, which is around four years old. Research found that rear-facing car seats can offer up to 75% more protection if your young child is involved in a car accident.
