The Bonbijou Easy Rider 2020 is suitable for children from 9-36 kg. The 5-point harness secures your child when below 18 kg, and can be removed to covert the car seat to a belted booster seat once your child is above 18kg. This car seat uses ISOFIX connectors to secure the seat to the vehicle for a fuss-free installation. The multiple head rest levels also adjusts to your growing child’s height easily. It also has 4 recline positions.
