Thank you for viewing. The Fladea Grow ISOFIX AC protects the ideal posture in three steps, starting with a flat bed. Immediately after birth, it's important for the baby to be able to breathe comfortably. A "flat" bed protects the wobbly neck and head. Because the baby can lie "flat" like at home, they can sleep soundly even in the car. Furthermore, it supports the ideal posture with a rear-facing seat from when the neck is stable to around 1.5 years old, and with a forward-facing seat from around 1.5 years old to around 4 years old. It changes according to the baby's growth, from newborn to around 4 years old. It is an ISOFIX fixed type that can be securely and easily installed in the car.
