Ready for the next step on your little one's journey? The DUALFIX 5Z is the perfect follow-up seat to use after the BABY-SAFE 5Z2. Easily clicked onto the FLEX BASE 5Z (SOLD SEPARATELY) it provides superior protection and cosy comfort for many journeys to come, until your child is four years old. Thanks to the 360° rotation of the FLEX BASE 5Z, the seat can be used rearward and forward facing, making it easy to get them in and out of the car, even in the tightest of parking spots.
Children grow fast - but even if they've outgrown their clothes, they'll still fit their car seat. When you move on from an infant carrier, the DUALFIX 5Z keeps your little one protected and comfortable in the car from 3 months to 4 years. The seat has 12 recline positions and a V-shaped headrest that provides support and space as your child grows, so they can take a nap or explore the world with their eyes. Plus, it can be rotated effortlessly from any position without needing to disturb your little one. All-round protection-no compromises
Make safety your top priority with the DUALFIX 5Z car seat. Built to more demanding specifications than the current industry standard (UN R129), your child is protected on every journey, even if the unthinkable happens. The DUALFIX 5Z includes optimised side-impact protection system to provide superior safety in a side collision. Plus it has an innovative support leg and solid rebound bar to protect your child from any impact. You'll have peace of mind wherever your adventures take you.
Smart and adjustable support leg

The support leg provides extra stability for the infant carrier base via the vehicle floor. It minimises the tilting and rotational movement and reduces the forward movement forces exerted on your child in a crash situation, helping to protect them. For a secure installation, the support leg can be adjusted to suit the height that’s best for your car. The easy-to-read indicator shows you when the support leg is positioned firmly on your vehicle’s floor, changing from red to black when correctly installed. Additionally, the support leg will notify you with a sound if not correctly installed.

Protect your child from a side impact thanks to the integrated SICT inside (Side Impact Cushion Technology) which absorbs the energy of a collision and keeps your little one away from the impact. Plus it provides superior safety at every angle so there's no need to adjust it when you recline or rotate the seat.
ISOFIX ratchet system
The ISOFIX ratchet system allows the ISOFIX arms to extend so you can easily fit or remove the infant carrier base from the ISOFIX anchorage points in the car. Once the ISOFIX connectors are engaged, push the base until it touches the back of the vehicle seat. This prevents the infant carrier from lifting upwards in case of an impact.
Multi-recline positions
Keep your little one happy and comfortable even on long journeys. The DUALFIX 5Z has multiple recline positions that you can adjust easily. With 6 forward-facing and 6 rearward-facing positions, select one that allows your child to relax or take in the view - so they're content and you can enjoy a stress-free journey.
Comfortable, protective headrest
Ensure optimum protection in a side collision: the V-shaped headrest is specially designed to limit the movement of your child's head, protecting their neck if the worst happens, whilst giving them space as they grow. It's quick and easy to adjust the headrest and harness simultaneously, so your child's completely comfortable, whatever their height.
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.
