XP-PAD
XP-PAD absorption pad, which protects your child's neck in the event of a frontal impact during an accident, reducing the sudden forward movement of the head by up to 30%, preventing your child's chin from hitting their chest. In addition, the XP-PAD adds a comfortable padded edge so that the seat belt does not cut your child's delicate skin.
SICT (Side Impact Cushion Technology)
Advanced Side Impact Protection - SICT (Side Impact Cushion Technology) reduces the force of an impact by up to 40% in the event of a side collision. Simply attach the SICT to the side of the car seat and your child is safe.
SECURE GUARD*
Protection in all the right places with Secure Guard, with the addition of a fourth additional contact point to securely fasten the lap belt to your child's pelvis, instead of their belly, reducing abdominal forces by up to 35%, without restricting your child's movements.
*Only available in the CLASSIC and STYLE collections
Ergonomic and easy-to-adjust headrest
Comfortable and protective headrest, ensuring optimal protection in the event of a side collision, with a V-shaped headrest. It is quick and easy to adjust for maximum comfort and for any height.

360º Rotation
Once placed on the Vario 5Z Isofix Base (sold separately), the Dualfix 5Z i-Size rotates 360º to travel rearward-facing from 61 cm up to 105 cm (recommended), or if you wish, it can be turned forward-facing from 76 cm and 15 months of age. We recommend using the Dualfix 5Z rearward-facing for the entire use of the car seat, as this orientation best protects the cervical vertebrae and head in the event of a frontal collision, the most frequent type of accident on roads. In addition, the Dualfix 5Z rotates 90º to both sides to place and adjust the harness for the child from the open car door and can rotate in any recline position.Maximum comfort for the child
Reclines in six positions, both rearward and forward-facing. The rebound bar can be adjusted by 8º to better adapt to the car seat and offer up to 10% more legroom.
Increased side protection
The soft, padded side wings act as a protective shield that helps absorb the force of a side impact, thereby reducing the risk of injury to the child.
5-point harness with neoprene pads
The child is secured with the five-point harness both rearward and forward-facing, which, in the event of a collision, distributes the impact force among the five attachment points: two on the shoulders, two on the hips, and one on the central buckle located between the legs.
Safe installation
The Dualfix 5Z's Vario 5Z Isofix Base is installed with ISOFIX and a support leg. Compatible with any vehicle seat. Base sold separately here.
Isofix with Pivot Link
The ISOFIX connectors feature the Britax Römer patented Pivot Link system, which initially directs the impact force downwards, pushing the seat against the vehicle seat and absorbing energy, then continuing to move forward more smoothly. This reduces the risk of head and neck injuries.
Modular base system
The Vario 5Z Isofix Base is compatible with the Baby-Safe PRO, Baby-Safe 3 i-Size, Baby-Safe Core, and Dualfix 5z.
Removable textile
Both the textile and the chest pads are easily removed for machine washing, without removing the harness.

✅ 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.
