Winner of the prestigious Kind+ Jugend Innovation Award in the World of Traveling Kids category

The car seat Flex FIX 2 is an enhanced version of the multiple award‑winning model iZi Flex FIX i‑Size. It is a high‑back booster seat for children with a height of 100 to 150 cm, combining excellent safety features, high comfort standards and flexible solutions for easy adjustment, installation and room for up to three people in a row.

With the introduction of the new regulation (UN R 129), the Flex FIX 2 is the next stage in the journey. The seat features an innovative, modular protection system that ensures maximum safety meeting the highest market requirements.

Safety
The Flex FIX 2 seat has an innovative headrest construction with side impact protection Dynamic Force Absorber™. It is compliant with the latest regulation (UN R 129), thus meeting the highest safety requirements.
The modular protection system provides maximum safety. The seat does not have armrests to eliminate incorrect use of the seat, such as a badly positioned lap belt, which could lead to serious abdominal injuries.
To further protect the child, the seat is equipped with SIP+ side protection, placed on the outer shell of the seat.
Although the Flex FIX 2 has been approved according to the new regulation without the SIP+ add‑on, our experience and additional tests show that the SIP+ add‑on provides even greater safety for the child because it significantly reduces the forces acting on the child in a side impact.
The SIP+ add‑on should always be mounted on the side facing the car door.

Comfort
The backrest height can be adjusted for heights from 100 to 150 cm using knobs located on the sides of the seat, so adjustment can be made even while the child is seated. The seat is also equipped with a reclining backrest – an extremely useful feature during long journeys.
Experience gained from the Seat Belt Adapter for pregnant women inspired us to integrate a lap belt guide into the Flex FIX 2. This integrated solution prevents "submarining" (sliding under the belt during a collision) and guarantees correct lap belt routing.
A high‑quality magnetic buckle makes fastening and unfastening easier.
The V‑shaped headrest perfectly supports the child's head while sleeping and ensures good side visibility. It is designed to work together with the integrated headrests in the car.
An additional advantage is the carry handle at the top of the headrest, allowing safe transport of the seat.
To eliminate problems with the ISOfix connectors retracting while inserting them, a lock has been placed at the front of the seat, making it easy and quick to connect the seat to the car's ISOfix points.

Space – 3 in a row
Place up to 3 children in car seats on one bench by removing the side panels from the middle seat – more space = equally safe.
