Maxi-Cosi Marble baby car seat is specially designed to ensure that during long trips the baby has a natural lying position and a good sleep. Very soft shock-absorbing padding delicately envelops the newborn, and 8 different headrest positions allow the seat to “grow” with the baby. In addition, the safety seat is equipped with an extra-large sun canopy with a mesh peek-a-boo window.

In the car, the baby seat is placed on the special Marble base (included) in the rear-facing direction, and the Click & Go system provides easy and quick installation. At the same time, the safety seat can be used not only in the car but also installed as a carrycot on the chassis of Maxi-Cosi and Quinny strollers, and built-in memory buttons allow it to be done with one hand. To install the baby seat on the chassis of other manufacturers, you need a special adapter.

Maxi-Cosi Marble Baby Car Seat complies with the highest R129/03 i-Size safety standard.

Please note:

The safest place to install a baby/child car seat is the back seat of the car.


Installation of a safety seat in the car’s front seat is allowed only if the passenger airbag is deactivated!


Children under 4 years of age are recommended to travel in the car in the rearward-facing direction. This is due to the anatomical features of the growing child’s body and provides additional protection for the baby’s head and neck in road conditions (e.g., sudden braking).
