i-Size or R129 is the most up to date European safety standard for car seats. These car seats must be fitted in your vehicle using the ISOFix connectors. This reduces the risk of incorrect fitting. Another safety bonus is the addition of a side impact crash test in the approval process.

How to pick the best car seat:

  • R129 car seats must be fitted have ISOFix connectors. However depending on your child’s height you don’t have to install the seat in the car using them.
  • The new regulations are based upon the child’s height, not their weight.
  • When using R129 car seats for your baby, you must rear face them until 15 months.
  • All of our seats have adjustable headrests and recline positions to keep your little one safe and supported at all times.
  • R129 regulation seats also must have a fixed backrest and side impact protection.
