PRO installation: quick, safe and straightforward

No ISOFIX in your car?
It can also be installed without ISOFIX using the 3-point seat belt.

|---|---|---|---|---|
| Classic | Simpler line, one main fabric | Balanced comfort | No | Those who want a basic, functional option |
| Style | Variety of fabrics and details | Mesh + ventilation for better comfort | Yes | Everyday use, summer trips and families who prioritise breathability |
| LUX | More premium, with additional faux-leather details | Premium feel + enhanced comfort | Yes | Those who want the most exclusive finish |
Frequently asked questions (the ones that really matter)
What is the Britax Römer XP-PAD?
The XP-PAD is a safety feature that, in the event of an accident, reduces sudden forward head movement by up to 30%, helping prevent your child’s chin from hitting their chest. It also adds a comfortable padded edge so the seat belt doesn’t dig into delicate skin.
What is SICT (Side Impact Cushion Technology)?
SICT side-impact protection reduces the force of a side collision by up to 40% and directs forces away from the child. Simply position the SICT on the side of the car seat.
How do you install the KIDFIX PRO?
It must be installed using the vehicle’s 3-point seat belt, and it can also be anchored to the car’s ISOFIX points. ISOFIX helps keep the seat firmly in place even when your child isn’t using it.
Can it be installed using only the seat belt?
Yes. It can be installed with the vehicle’s 3-point seat belt, which is useful if you move the booster between cars that may not have ISOFIX anchors.
When does a child no longer need a car seat?
In many countries, a child may not need a car seat once they reach 135 cm or more. Even so, it’s recommended to keep using a child restraint system up to 150 cm for better belt fit and improved safety.
What precautions should I take when travelling with children?
Make sure you use a restraint system suitable for your child’s height and weight. Install it correctly (ISOFIX and/or 3-point belt) and check regularly that features like XP-PAD and SICT are in good condition. Keep loose objects out of reach to reduce risks during sudden braking or a collision.
