We recommend keeping children rear-facing for as long as possible, at least up to the age of four. After that, your toddler can use a booster. The best booster is the one that provides the right belt fit and comfort for their size and age, as well as the length of the trip. A good belt fit means the lap belt sits over the hips, toward the thighs and that the shoulder belt rests comfortably in a mid-shoulder position. A booster seat with a backrest provides extra side support and is a good choice for younger children, especially on longer trips. The booster cushion, and even more so, integrated boosters, are safer and more practical options that raise the child into the correct position for the safety belt. Together with the vehicle’s other protection systems, this helps keep your child safe.
