All-around safety

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 our TRIFIX 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 our patented Pivot Link ISOFIX System and Top Tether with rip stitch technology provide safety in the event of a frontal collision.

Easy installation with integrated ISOFIX and Top Tether

Thanks to ISOFIX and Top Tether TRIFIX 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. Since TRIFIX i-SIZE can be used on all i-Size seating positions, as well as on any vehicle seats with ISOFIX and Top Tether anchorage points it is suitable for a wide range of cars. Moreover, as the ISOFIX connectors are integrated into the base of the car seat, your infant carrier base stays free for use when a younger sibling arrives.


Adjustable V-shaped headrest and 5-point harness

TRIFIX i-SIZE has been designed for the growing needs of children from 76 cm to 105 cm tall. Our new V-shaped headrest is specially designed to control the movement of your child’s head in the event of a side collision. Plus, when you adjust the headrest height the 5-point harness adjusts as well, ensuring it is at the correct height, keeping your child safe in the seat’s protective shell.

Fitting a car seat 100% safely can be tricky because every car is different. That’s why Britax co-developed ISOFIX, a standard system of connection points featured in almost all cars. The ISOFIX system establishes a secure and firm connection between the child’s car seat and the car. So every time you, or a grandparent or friend, have to fit the car seat into your car, or into another car, fewer mistakes can be made.

TRIFIX i-SIZE specific requirements - a safe installation is completed with the use of Top Tether to allow optimum stability.

Our i-Size car seats will fit all i-Size approved seating positions, so please check your vehicle owner's manual for i-Size approved seating positions.

FEATURES

Superior Side Impact Protection
01 FEATURE SICT inside TRIFIX i SIZE 1180x830px 72dpi

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. And you don’t have to adapt or adjust anything – SICT inside is always ready when you need it.

The Britax Römer Pivot Link System
Feature07 Pivot Link ADVANSAFIX III SICT 1180x830px 72dpi

In case of an impact, our 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.

Top Tether with rip-stitch technology
03 FEATURE Top Tether TRIFIX i SIZE 1180x830px 72dpi

Our 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.

V-shaped headrest
04 FEATURE V shaped headrest TRIFIX i SIZE 1180x830px 72dpi

Specially designed to control the movement of your child’s head, our 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.

Deep, protective side wings
05 FEATURE SideWings TRIFIX i SIZE 1180x830px 72dpi

Our 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.

5-point harness
06 FEATURE 5 Point Harness EVOLVA 1 2 3 1180x830px 72dpi

We believe 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.

Soft neoprene performance chest pads
07 FEATURE Neoprene Chest Pads TRIFIX i SIZE 1180x830px 72dpi

Our 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.

Multi-recline positions
08 FEATURE Multi recline KING II LS 1180x830px 72dpi

Keeping your child comfortable while traveling 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.
