The Viaggio Flex 120 has the unique capability to fully accommodate a child’s growth with it’s 4D Total Adjust Technology. This means the booster can be adjusted in four different locations: 1) the headrest can adjust to five different positions vertically, 2) the upper backrest adjusts three positions vertically, 3) the side wings can expand out three positons, 4) the seat can recline five positions. These adjustments can be made independently from each other, allowing for a truly original experience in comfort.

Securing the Viaggio Flex 120 to the car is made easier with the integrated rigid LATCH, equipped with a blind lock attaching system which prevents the seat from being accidentally released by another passenger. The rigid LATCH can tuck back into the base, allowing for an easy installation if LATCH is not available. An aluminum-reinforced backrest ensures safety and protection against whiplash in the case of a front-end accident and additional protection in the event of a rear-end collision. EPS throughout the side wings and headrest also serves to absorb energy during a crash.

The backrest of the Viaggio Flex 120 can fold down onto itself when not in use, even while attached via rigid LATCH. Transporting and storing the seat is also made easier because of the folding capability, making the booster one of the most practical around.
