The Britax ADVANSAFIX IV R was cleverly developed so that children from 9 to 36kg (approx. 9 months – 12 years) can travel safely and comfortably.

Thanks to the FLIP&GROW function, you can switch from the integrated 5-point harness to the 3-point seat belt as your child grows, with just a few simple steps. In addition, ADVANSAFIX IV R provides maximum flexibility and protection for all ages thanks to its advanced safety features.

When your child reaches 18kg, this is when you switch the secure 5-point harness for the car’s 3-point seat belt, the incorporated SecureGuard holds the lap belt in the optimal position over the pelvic bones, reducing the risk of abdominal injuries. Plus, the adjustable SICT and V-shaped headrest provide protection in the event of a side impact collision.

There is nothing to remove from the seat when converting, so nothing can get lost, and it can be converted back to the harnessed mode at any time. The extra soft padding and EasyRecline with three adjustable recline positions, ensures that your child will be comfortable on every journey.

Good to know: The ADVANSAFIX IV R has been tested by ADAC (ADAC Motorwelt 06/2019) with a rating of “GOOD” and a grade of 2.3.
