Maxi-Cosi Luna Pro Harnessed Booster Seat
From lower shoulder marker, up to upper shoulder marker (~6 months to 8 years).

Pros / Cons
Pros
- Keeps a child fully harnessed to about 8 years - no harness-to-booster conversion and no belt-positioning stage to manage.
- Auto-adjusting harness with 8-position headrest removes rethreading as your child grows; the dual-action buckle adjusts harness height and depth together.
Cons
- Forward-facing only from about 6 months: children who still fit rearward-facing need a different seat first.
- Large 475 mm-wide, ~10 kg shell with only two recline positions can be hard to fit into smaller cars or three-across layouts.

Shortlist the Maxi-Cosi Luna Pro when you want one fully harnessed seat to carry a child from about 6 months to roughly 8 years without ever managing a harness-to-booster conversion: the 6-point harness auto-adjusts with the 8-position headrest, so there is no rethreading, and Air Protect head cushioning with integrated chin supports covers the side-impact basics. The honest boundaries are forward-facing only — children who still fit rearward facing need a rearward seat first — and the shell is large and heavy for the class, so check vehicle space and recline clearance in your actual car before buying. The bamboo wicking fabric and two-position recline help long rides, and the maker backs the shell with a lifetime warranty and accident exchange service. Before buying, confirm your child’s seated shoulder height sits inside the lower-to-upper marker range and that the harness routes cleanly at the height you need.
