Maxi-Cosi has car seats for children up to 12 years old. You can use some seats from birth already, like the Maxi-Cosi Emerald 360. Choose the right seat based on the height of your child. In the Netherlands, all children up to 135cm tall should be in a car seat. For older children, they are seats without a seat belt harness. You secure these with the seat belt and Isofix. Safety comes first for us. All our car seats have Isofix and meet the latest security norms R129/i-Size.
