The Group 2/3 car seat is designed for children from 100 to 150 cm (approximately 4 to 12 years old) and allows them to be installed safely in the car. With its comfortable seat and height-adjustable headrest, it offers the child optimal comfort during car journeys. Isofix fixings allow for easy installation and greater stability of the car seat. This car seat complies with the new R129 regulation known as "i-Size". This new regulation strengthens the requirements for child safety in cars with more severe frontal collision tests and side collision tests. This European regulation makes it compulsory to have the rear-facing position up to at least the age of 15 months for Isofix car seats. Babies' necks are very fragile, and it has been shown that the rear-facing position offers better protection for children, especially in the neck and head area. In addition, the installation of the seats is more secure with the Isofix system because it avoids installation errors.The advantages of the Twiddly II VERTBAUDET Group 2/3 Car SeatFor children from 100 to 150 cm / 39.4 to 59.1 in (approx.)
