The Kiddy Smartfix is unique! Between the ages of 4 and 12, children will grow around 4 to 5 centimetres per year. This results in an average growth of almost half a metre during the life of a child car seat. Therefore the Kiddy Smartfix is designed to easily adjust along three dimensions – height, width and depth - to perfectly fit a growing child, no matter what their age. The Kiddy Smartfix uses ISOFIX connectors to provide a secure attachment to the car. High performance impact-absorbing materials are built into the head and shoulder areas to protect the child. The Kiddy Shock Absorber has new geometric design. The Kiddy Shock Absorber, along with the diagonal belt guide, will reduce forces / load in the event of a frontal impact.
