Maxi-Cosi Rodi AP
From lower shoulder marker, up to upper shoulder marker (~4-8 years).

Pros / Cons
Pros
- The tall adjustable back and expandable side wings give growing booster riders more fit range than a fixed low-back booster.
- Clear belt guides and multiple recline positions help the adult belt sit consistently while keeping longer trips more comfortable.
Cons
- It is booster-only, so it is the wrong step if the child still needs an inbuilt harness for fit or maturity.
- Check the top-tether anchorage, vehicle belt geometry, and shoulder markers in the actual car before buying.

Maxi-Cosi Rodi AP is for a child who is genuinely ready for a belt-positioning booster and needs a high back that can keep adapting as shoulders rise. Its six-position headrest, expandable side wings, belt guides, and recline choices are useful when the goal is consistent adult-belt placement rather than another harness stage.
That distinction is the buying boundary: it has no inbuilt harness, so weight alone is not enough. The child must sit correctly for the whole trip. Before buying, test shoulder and lap-belt geometry in the actual seating position, confirm the shoulder markers and top-tether anchorage, and follow the current Australian manual rather than relying on age shorthand.
