Lionelo Aart i-Size

Pros

  • Rear-facing use to 105 cm covers the full harness stage rather than stopping at the legal minimum.
  • Three-point-belt installation lets it move to vehicles without ISOFIX anchors.

Cons

  • A long belt route is less forgiving than a well-indicated ISOFIX setup; practise a firm install before daily use.
  • It does not rotate, so loading a rear-facing infant requires more reach into the vehicle.

Lionelo Aart i-Size suits a family that needs one belt-installed 40-150 cm seat, including cars without ISOFIX, while keeping the harnessed child rear-facing to 105 cm. That rear-facing boundary covers the full integral-harness stage rather than ending at the legal minimum, and the same shell later becomes a booster. The tradeoff is installation effort: its longer three-point-belt route is less forgiving than a clearly indicated ISOFIX setup, and the seat does not rotate for loading. Before buying, practise a firm installation in every intended car, confirm the belt is long enough and routes without twisting, then check whether reaching into the vehicle works for daily rear-facing loading.
