Kinderkraft I-FIX Endura Safe Group 1/2/3 Car Seat - Grey

I-FIX ENDURA SAFE (61–150 cm) – car seat for older children from the modular ENDURA SAFE system
Your child is growing fast, and you're looking for a car seat that can keep up? I-FIX ENDURA SAFE is designed for children from 61 to 150 cm in height.
It’s part of the ENDURA SAFE modular system – a solution that ensures safety and comfort at every stage of your child's development.

Safety that gives peace of mind - I-FIX ENDURA SAFE meets strict European safety standards – crash-tested for frontal and side collisions, taking into account the real forces acting on a child’s body. This means a higher level of protection and peace of mind on every trip.

H-GUARD+ – advanced head protection system - The multilayer headrest is designed to surround and stabilize your child’s head from all sides. It protects sensitive areas during side and rear impacts, providing proper support and enhanced safety.

Usage range: 61–150 cm - Allows for rearward-facing travel (RWF) up to 105 cm/21 kg, and then forward-facing (FWF) – until the end of the car seat stage.

SIDE PROTECT SYSTEM+ (SPS+) - Side wings reinforced with an additional bumper absorb the energy of a side impact, protecting critical parts of the child’s body – shoulders, hips, and torso.

EPP foam throughout the shell - Flexible and durable foam that disperses collision energy, enhancing child safety in the event of an accident.

Installation on ENDURA SAFE FX base - The seat is installed exclusively with the modular ENDURA SAFE FX base (sold separately), which ensures stability and proper positioning in the car.
Indicators for correct installation (ISOFIX, support leg, seat latch) and the one-button release feature make daily use easier.
The base is installed only once – even when the child no longer uses the internal harness, there’s no need to dismantle anything or fold away the support leg.

360° rotation – less effort, more comfort - The seat rotates smoothly in all directions. This makes buckling your child easier and allows a convenient switch from RWF to FWF without removing the seat – saving time and reducing installation errors.

Seat recline adjustment – comfort in both directions - The seat can be reclined in four positions in both rearward and forward-facing modes – especially useful when your child takes a nap during the trip.

One-hand adjustment of the headrest and internal harness - With one simple movement, you can adjust the headrest and harness height to your child’s size – quickly, conveniently, and without mistakes. This means not only comfort, but most importantly, safety.

Breathable structure and premium upholstery – comfort on every journey - The ventilated AIR SHELL structure and breathable AIR FLOW fabric ensure proper air circulation, even on hot days. Soft, durable materials are pleasant to the touch and easy to remove and wash – because comfort and cleanliness go hand in hand.

Deep, comfortable seat - Provides a stable and ergonomic position, even on longer trips. More space means more comfort.

Internal harness storage - When the 5-point internal harness is no longer needed, it can be tucked away easily – no dismantling required.
