Product overview

When your baby is growing into a toddler their needs might change, but what doesn't change is their need to be protected. That's why the Trifix 2 i-Size provides all-around safety for your little one. Thanks to the large, padded side wings with SICT inside and the V-shaped headrest your child is protected in the event of a side collision, while the patented Pivot Link ISOFIX System and Top Tether with rip stitch technology provide safety in the event of a frontal collision.

  • Thanks to ISOFIX and Top Tether the Trifix 2 i-Size is not only easy to install, but it also allows for more space in the footwell of your vehicle. The ISOFIX connectors are integrated into the base of the car seat and offer maximum safety. Plus, there's no need to change the installation during the time you're using the seat.

  • In case of an impact, the patented Pivot Link System directs the force first downward, into the vehicle seat, and then forward, more gently. Greatly reducing the risk of head and neck injury.

  • The integrated SICT inside offers your child superior protection in the event of a side collision. SICT inside keeps your child away from the impact while absorbing energy at the same time.The soft, padded side wings act as a protective cocoon that helps to absorb the force from a side impact, reducing the risk of injuries to your child.

  • Specially designed to control the movement of your child's head, the V-shaped headrest ensures optimal protection in the event of a side collision while providing ultimate comfort at the same time. Plus, the headrest and harness can easily be adjusted from the front of the seat to suit your child's height.

  • The v-shaped Top Tether prevents the seat from rotating and reduces the forward movement of the child in the event of a collision. Due to its twin anchorage points, it offers even greater stability and security for your child than a seat with conventional tethers. Plus, its unique pattern of stitches is designed to progressively rip in a controlled fashion, absorbing the force of the frontal impact.

  • Britax believes a 5-point harness is the safest way to secure your child in a car seat because it keeps your child safe and tight in the seat's protective shell. In case of a collision, the harness distributes the forces of the impact across 5 points, two at the shoulders, two at the hips and one where the harness buckles between the legs. This helps to protect your child from all directions of impact.
  • Keeping your child comfortable while travelling is a must. That's why this seat was designed with four recline positions that you can adjust with ease, offering a stress-free journey with a happy child.

  • The new, soft neoprene performance chest pads fit comfortably on your child's chest. They help reduce your child's movement in the event of a collision and add even greater comfort to the 5-point harness. Plus, they can be easily removed for washing without disturbing the harness.
