The Britax Römer Evolvafix i-Size Car Seat 76 - 150 cm is a versatile and safe car seat designed to protect children from 15 months to 12 years. It is approved to the new i-Size regulation, ensuring maximum safety and flexibility. The seat can be easily converted from a harnessed seat to a highback booster seat, allowing children to benefit from 5-point harness protection until they reach 105 cm or 22 kg. With its innovative features and adjustable design, this car seat provides comfort and security for growing children.

  • i-Size Safety for All Ages: The Evolvafix is designed to provide optimal safety for children from their toddler years to when they no longer need a child car seat. It meets the new i-Size regulation and offers a 5-point harness that can be used for longer, accommodating children up to 105 cm or 22 kg.
  • Flexibility at Your Fingertips: With the Flip&Grow function, transitioning from the integrated 5-point harness to the car's 3-point seat belt is quick and easy. The seat can be converted back at any time without removing any parts. The EasyRecline feature allows for comfortable recline positions without readjusting the installation.
  • Enhanced Protection and Comfort: The Evolvafix features a high back seat design that provides head-to-hip protection, especially in side collisions. The V-type headrest controls head movements and offers optimal side impact protection. Soft chest protectors reduce movement during a collision and can be easily removed for cleaning. The SecureGuard provides an additional attachment point, reducing forces acting on the abdomen in a frontal collision.


  • Age Range: 15 months to 12 years
  • Weight Range: Up to 22 kg
  • Height Range: 76 to 150 cm
