Overall, this is a solid booster seat for older kids that offers safety, convenient features, and a durable design.
Although TTPM noted that this can be used for ages 4 and up, it is more important to follow that weight and height designations from Diono. It is for use with children 40-120 pounds or 38-63 inches in height.
