Why you should buy the Britax Romer Advansafix PRO Car Seat

✅ From 15 months to 12 years
✅ 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 safety standard R129 (i-Size). 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 at 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, in addition to 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 restrained directly with the car's three-point seat belt, in combination with SecureGuard. This piece adds a fourth anchor point to the belt to keep the lap section correctly positioned over the pelvic area, preventing it from dangerously riding up 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, and store the harness (without removing the chest pads) in the back of the backrest, behind the cover, so it doesn't get lost. Then, move the FLIP&GROW adjustment plate, rotate it to position the SecureGuard over the car seat, and the transition is complete.
