Review: Graco Junior Maxi i-Size R129 Highback - Got this item as I had used it before with my other grandchildren. Great child seat as it grows with the child, who likes the cup holders that can be used to hold not only drinks but hide little treats as well. Strong, sturdy quality, easy to use & set up.
