✅ From 15 months to 12 years old
✅ From 76cm to 150cm
✅ Isofix Installation
✅ Approval: R129 (i-Size)

The Advansafix PRO car seat is adaptable, suitable for children from 15 months old and 76 cm tall up to 150 cm (approx. 12 years), approved under the R129 (i-Size) safety standard. It always travels forward-facing, and the transition from the five-point harness (76-105 cm or 22 kg) to the three-point seat belt with SecureGuard (100-150 cm) is quick and easy with the FLIP&GROW system.

76-105 cm or 22 kg: 5-point harness

From 76 cm and 15 months up to 105 cm tall or 22 kg in weight (whichever comes first), the child is secured in the car seat with a five-point harness, which distributes impact forces across five points: two on the shoulders, two on the hips, and one on the buckle located between the legs. The harness pads reduce the child's movement in case of a collision, while also providing greater comfort for the harness. In this stage, the car seat is installed using Isofix and a top tether.

100-150 cm: seat belt with SecureGuard

From 100 cm in height (and no later than 105 cm or 22 kg), the child is secured directly with the car's three-point seat belt, in combination with SecureGuard. This feature adds a fourth anchor point to the belt to keep the lap section in the correct position over the pelvic area, preventing it from dangerously rising to the abdomen. It helps reduce forces on the abdomen by up to 35% in case of a frontal impact. In this stage, the car seat is installed using Isofix.

When it's time to transition from the harness to the seat belt, it will be much easier thanks to the FLIP&GROW function. Simply press a button to unlock the headrest and adjust it to the required height, then store the harness (without removing the chest pads) in the back of the backrest, behind the cover, so it doesn't get lost. Next, move the FLIP&GROW adjustment plate, rotate it to position the SecureGuard over the car seat, and the transition is complete.

A post shared by Britax Römer (@britaxromer_pt)

R129 i-Size approval is more stringent than the previous R4404 approval and, as such, ends up being a safer option.

It is a patented technology by Britax Römer that allows for a more comfortable and ergonomic position for newborns. This patented full recline mechanism allows the flatness of the lying position to be adjusted according to the child's height. The position automatically changes when adjusting the headrest, increasing space according to your child's development. The shoulder straps also automatically adjust when regulating the headrest.
