Designed to keep your child safe and comfortable from 100 cm to 150 cm (approximately 4 to 12 years), the Stepup i-Size ISOFIX car seat is the last car seat you'll ever need to buy for this stage.

Safety You Can Trust
The Stepup i-Size meets the stringent UN R129 regulation, which requires extended side-impact testing and a minimum height requirement — giving your child significantly more protection than older Group 2/3 seats. The rigid ISOFIX connection anchors the seat directly to your car's chassis, removing the risk of incorrect belt-only installation.
Comfort for Every Journey
Thick, breathable padding and a one-hand adjustable headrest with multiple height positions mean your child can settle in comfortably whether it's the school run or a long motorway trip.
