Kids do not come in one size, so it does not make sense that a booster for a growing child should! The Nuna AACE grows every which way, so you don't need to worry about your child's car safety! The AACE combination booster car seat is just like the rest of the Nuna brand - sleek and sophisticated, but it also offers the advanced safety features we want to protect our little ones. Being the first of its kind, the AACE offers both horizontal and vertical growth, unlike most boosters that only grow vertically.
