What is R129 i-Size approval?
R129 i-size approval is more demanding than the previous R4404 approval and, as such, ends up being a safer option.
What is lie-flat technology?
It is a technology patented by Britax Römer that allows a more comfortable and ergonomic position for newborns. This patented full recline mechanism allows the flatness of the lying position to be adjusted according to the child's height. The position automatically changes when adjusting the headrest, increasing space according to your child's development. The shoulder straps also automatically adjust when adjusting the headrest.
