Maxi-Cosi Tanza B

Pros

  • At 4.2 kg and foldable, it is easier to carry between cars than a heavier fixed booster.
  • Belt-only installation avoids relying on ISOFIX anchors when the car has a compatible three-point belt.

Cons

  • It cannot be used below 100 cm or with a two-point belt; the shoulder and lap belt must follow the seat guides.
  • Belt-only installation makes checking the belt route and vehicle-seat compatibility essential each time you use a different car.

The Maxi-Cosi Tanza B is a forward-facing booster for children from 100-150 cm, not a seat for a smaller child who still needs a harness or rear-facing travel. At 4.2 kg, it folds for carrying between cars or storing at home. Its belt-only design also means there is no ISOFIX connection to install.

Before buying, check the exact seating position in every car: the manual requires a compatible forward-facing vehicle seat and an approved three-point belt, and forbids a two-point belt. Route both lap and shoulder sections through the marked guides exactly as shown, then confirm the belt lies correctly on your child. Measure the folded seat against your storage space if portability is the reason to choose it.
