Just as your little one takes their toy on every adventure, you can rely on the ADVANSAFIX PRO to be your child's faithful companion. Protecting your precious bundle on every journey and growing with them - from 15 months right up to 12 years old.
ULTIMATE SAFETY
Give your child the very best protection with the superior safety features of the ADVANSAFIX PRO, that grows with them from 15 months right up until they're 12 years old.
SICT, XP-PAD and SecureGuard work together to provide the best possible frontal and side impact protection in any accident.
COMFORT AND FLEXIBILITY AS THEY GROW
Give your little one a comfortable ride - even when they're not so little anymore! The spacious, softly padded seat and headrest adjust effortlessly for the perfect fit throughout childhood. There's no hassle for parents - adapt from 5-point harness to car seat belt as your bundle of fun grows from 15 months to 12 years.
PEACE OF MIND FOR PARENTS
Relax: there's no need to buy a new car seat as your child grows. The ADVANSAFIX PRO adapts and protects throughout your little one's childhood, so you can enjoy your adventures without the worry.
INDEPENDENT ISOFIX CONNECTORS
Install the ADVANSAFIX PRO effortlessly thanks to the ISOFIX connectors, which can be operated independently. You're fully in control, so they're fast and safe to connect without damaging your car's seats. And you're ready to get on with your day.
REDUCE THE RISK OF INJURY
Give your precious bundle greater stability and security if a collision occurs. The sturdy Top Tether minimises any rocking movement of the car seat during an accident, reducing the possibility of harm to your child's head and neck.
EXTRA SAFE 5-POINT HARNESS
Protect your child from serious injury by choosing a car seat with a 5-point harness. In the event of a collision, the harness distributes the force of the impact across all 5 points - the shoulders, hips and between the legs - to the seat's protective shell.
SOFT PERFORMANCE CHEST PADS
The soft performance chest pads of the ADVANSAFIX PRO bring even more comfort to the secure 5-point harness, and help reduce your child's movement in the event of a collision.
ADVANCED SIDE IMPACT PROTECTION – SICT
Give your child superior side impact protection and get peace of mind that they're safe on every journey. The Side Impact Cushion Technology (SICT) minimises the distance between the car and the car seat, reduces the force of a side impact by up to 40%*.
HEAD TO HIP PROTECTION
Know your little one is travelling in complete comfort and protection. Have peace of mind - the highback booster offers superior safety on every journey.
TAKING IT EASY WITH EASYRECLINE
Let you little one sleep comfortably throughout childhood travels with the EasyRecline function. Adjust effortlessly even when your child is in the seat, so you can relax too.
ISOFIX with Top Tether (76 – 105 cm)
This child car seat needs to be attached to the ISOFIX anchorage points of your vehicle. ISOFIX is a standard system of connection points featured in almost all cars. This establishes a secure and firm connection between the child’s car seat and the car.

Belted (100 – 150 cm)
