Description
Growing into the seat belt, with or without a backrest.
The Maxi-Cosi RodiSport in Authentic Black supports children who are ready to move from a harnessed seat to the vehicle seat belt. A removable backrest provides two configurations, while the adjustable headrest and belt guides help achieve the right fit.
At a glance
- 2 modes: high-back or backless
- 7 positions: headrest
- 18–45 kg: weight range
A backrest that adjusts as they grow.
With the backrest attached, the headrest offers seven positions to follow growth. Guides help place the shoulder belt across the centre of the shoulder. Once backless use suits both your child and vehicle under the manual’s requirements, remove the backrest for a more compact configuration.

Rigid anchors and correct belt positioning.
Rigid UAS connectors keep the booster in position, including when it is empty. They never replace the lap-and-shoulder belt that restrains your child. The manual also allows use without UAS when the required conditions are met. A lap-only belt is not suitable.

Limits and fit
Both modes are for children weighing 18–45 kg (40–100 lb) and measuring 110–145 cm (43–57 in). Your child must have outgrown the forward-facing harnessed seat and be able to maintain correct positioning. Check that the lap belt sits low on the hips, the shoulder belt crosses the centre of the shoulder, and head support meets the requirements for the chosen mode.
The backrest angle adjustment is only for fitting it flush against the vehicle seat back; it is not a rest position. Consult both manuals to select a compatible seating position.
Useful details for everyday trips
