Is it right for you? Decide in 30 seconds
For families who want i-Size safety, a stress-free daily routine, and a seat that supports baby from newborn onwards.
Extended rear-facing
The most protective orientation in a frontal impact. Ideal to keep rear-facing as long as possible up to 105 cm.
360° rotation for easy buckling
Turn it towards the door, place your child, then tighten the harness calmly. Less rushing, more consistent correct fit.
ISOFIX + support leg with indicators
Strong and clear setup: ISOFIX clicks in, support leg to the floor, visual checks. Helps reduce common install mistakes.
