Extended rear-facing is one of the safest ways to travel, reducing force on your child's neck in a frontal impact.
Swivel the seat with the easy rotation handle to face the door, boarding your child in any recline position without back strain.
All-round air ventilation channels heat away, with mesh fabric on the Plus version offering up to 6x more breathability.
Ingenious loops keep the harness out of the way as you get your child on board, making buckling up effortless.
The 12-position headrest adjusts for a tailored fit at every stage, with the harness automatically lengthening as you adjust.
The L.S.P. System, working with the energy-absorbing shell, significantly reduces the effect of side-impact force.
The ideal recline setting is available in both riding directions and boarding position, adjustable one-handed while baby sleeps.
Click the ISOFIX into the vehicle seat and extend the load leg, with visual indicators confirming the seat is ready to protect.
