The Joie i-Plenti car seat is the perfect seat for your child. The i-Plenti accommodates your child from 15 months to 12 years old, meets the highest safety standard R129, and features a luxurious design, allowing you to stick to your budget without compromising on safety or style. The 5-point harness of the Joie i-Plenti car seat fits children up to a weight of 19.5 kg or 105 cm (approximately 4.5 years old) and distributes the force across the strongest parts of the body, ensuring 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 the ages of about 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 headrest, providing your child with added comfort.
