Optimal protection for peace of mind

The latest R129/03 safety standard was the benchmark in the development of the Aton B2 i-Size. The infant car seat and matching Base One are approved to the latest standards, have i-Size compatibility and have undergone extended side-impact testing.


Reduces the force of a side-impact

The Linear Side-impact Protection System increases safety in the event of a side-impact collision. In combination with the energy-absorbing shell, it can reduce the force of a side-impact by approximately 25%.


Protects your child from sun and wind

The XXL sun canopy is made of UPF50+ fabric that protects your childs sensitive skin from the suns rays. Additionally, the foldable canopy reliably shields from wind when the journey continues outside the car.


Grows with your child in the first 24 months

Thanks to the 11-position height-adjustable headrest, the infant car seat grows with your child during the first 24 months. Head, neck and shoulders are supported while the harness automatically and comfortably adapts to each growth spurt.

At only 3.9 kg, the Aton B2 i-Size is easy and uncomplicated to position in the car or to carry before and after the trip.
