The Joie i-Plenti car seat is the perfect seat for your child. The i-Plenti supports your child from 15 months to 12 years of age, meets the highest safety standard R129, and features a luxurious design, allowing you to stay within budget without compromising on safety or style. The 5-point harness of the Joie i-Plenti car seat accommodates children weighing up to 19.5 kg or 105 cm (approximately 4.5 years old) and distributes the force across the strongest parts of the body, ensuring that your child is secured by the harness in the event of an accident. Transitioning from the 5-point harness to the car's seatbelt occurs between approximately 3.5 to 12 years (from 100 cm to 150 cm). To use the car's seatbelts, you must first stow the 5-point harness behind the backrest by folding down the back cushions. The AutoAdjust side wings automatically widen when you raise the headrests, providing your child with additional comfort.
