The Viaggio Flex 120 car seat grows along with the child. Its 4D Total Adjust Technology allows independent adjustments in four different locations. The headrest adjusts to five vertical positions, and the upper backrest adjusts to three positions. Side wings expand in three positions, and the seat reclines in five positions. Integrated rigid LATCH, equipped with a blind lock attaching system, makes securing the seat easy. An aluminum-reinforced backrest ensures safety and protection against whiplash, and the backrest folds down when not in use.
