What makes it special: a single car seat for 12 years with 360° rotation
The Stardust’s big advantage is that it covers every stage with a logical, simple system: newborn insert, harness use when needed, and transition to the seatbelt when appropriate. With 360° rotation you gain everyday comfort (getting the child in and out), and with rear-facing up to 125 cm / 21 kg you gain real safety for longer.

Real reasons to buy it today
Rear-facing up to 125 cm or 21 kg
Rear-facing is the safest option. The Stardust lets you keep your child rear-facing for years, reducing the strain on the neck and spine in frontal impacts.
360° rotation with side-stop
Turning it toward the door helps you place and buckle the child without forced postures. Ideal for daily use, school runs and short trips.
Semi-lock when turning toward the door
The automatic semi-lock position adds stability while you sit the child in or take them out. More control, fewer unexpected movements.
Airflow + rear ventilation
Breathable fabric and built-in ventilation reduce sweating and improve comfort in summer and on long trips.
