This Maxi-Cosi RodiFix S i-Size high back booster car seat keeps children safe and comfortable from about 3.5 to 12 years, growing in both height and width as they develop. Built to i-Size safety standards, this ISOFIX car seat features extra-high side wings, G-CELL Side Impact Protection, and AirProtect® safety cushions in the headrest that can reduce the risk of head injury by up to 20%. Three recline positions, an extending backrest, and soft AirProtect padding make naps and long journeys more comfortable, while a no-armrest design and ISOFIX connectors ensure quick, hassle-free installation and easy buckling. Intuitive height adjustment and expandable side wings mean this long-lasting group 2/3 seat adapts as a child grows, providing reliable protection and premium comfort for everyday family travel.
