Details and finishes
Key highlights you’ll notice straight away
360° rotation for effortless buckling
Rotate the seat towards the car door to place and harness your child comfortably, even in tight parking spaces. Then rotate back smoothly to the travel position without fuss.
12 recline positions (6+6)
Multiple recline angles both rear-facing and forward-facing, ideal for naps, longer drives or finding the most comfortable fit in different vehicles.
Integrated side impact protection: SICT inside
SICT inside is built into the seat to help absorb energy in a side collision, providing protection without needing external parts or extra adjustments.
Safety without compromise
DUALFIX PRO M is UN R129 i-Size approved and designed to protect in the most common road scenarios, with a strong focus on frontal and side impact performance.
UN R129 i-Size approval
Rear-facing use recommended for as long as possible
SICT inside for added side impact protection
5-point harness with soft chest pads
Optimised rebound bar for stability and extra legroom
Height-adjustable support leg with installation indicator
Long-lasting comfort for everyday travel
Children grow fast, and DUALFIX PRO M is designed to keep them secure and comfortable from around 3 months until approx. 4 years (61–105 cm). The V-shaped headrest provides supportive space as your child grows and helps limit head movement in a side collision, offering extra neck protection.
With 12 recline positions, you can fine-tune comfort for deep sleep, city errands or longer trips. The seat also rotates from any position, so daily adjustments stay quick and effortless.
Stable, guided installation
Installation is ISOFIX + support leg, a combination that helps reduce common fitting errors and delivers excellent stability. The independent, fully adjustable ISOFIX connectors make anchoring smoother, and the support leg indicator lets you confirm correct contact with the vehicle floor at a glance.
Everyday tip
Turning the seat towards the door makes harnessing much easier and reduces back strain. It’s especially helpful when your child is wriggly or you’re in a hurry.
