ECE R129 i-Size certification and robust side panels provide a high level of protection in frontal, rear, and side impacts.
The integrated headrest height adjustment automatically adapts the shoulder straps. Easy customization from newborn to bigger child.
Up to 3 forward-facing recline positions and flexible recline in RWF. The headrest with Memory Foam increases comfort and absorbs impact forces.
A safe and versatile choice for years of use: Lionelo Aart i-Size covers a child height of 40–150 cm, making it ideal from newborn to bigger child. Complying with the ECE R129 i-Size standard means successful frontal, rear, and side crash tests and selection by child height for a more precise and safer fit.
In the early stage it enables RWF – rear-facing up to 105 cm, later switching to FWF – forward-facing. Protection is enhanced by reinforced side panels and Memory Foam in the headrest, which absorbs impact forces. The integrated headrest height adjustment simultaneously adjusts the shoulder strap height, so the seat easily adapts to your child’s growth.
For everyday comfort there is recline adjustment (3 FWF positions + flexible RWF), a 5-point harness with anti-slip covers, and a soft newborn insert. Covers made from durable fabrics are easy to maintain and the ergonomic design ensures comfort even on longer trips.
