Why parents love it (in real life)
What stands out once you actually use it: easy loading, confident safety, and comfortable rides from day one.
1) One-button rotation = easier days
Rotate towards the door to load and buckle without twisting your back. Rotate back to the chosen travel direction and you’re ready to go.
2) Rear-facing up to 105 cm
Keep your child in the safest direction for longer within the approved range (40–105 cm / up to 20 kg).
Forward-facing use is allowed from 76 cm (many families choose to delay the switch as long as possible).
3) Short rebound bar = more legroom
The compact rebound bar helps create extra space for growing legs while still supporting safe rear-facing travel.
4) Multiple reclines + quick adjustments
Recline options in both directions and easy headrest/harness adjustment help you keep the fit comfortable as your child grows.
