GU MODE 76-150 cm is the practical choice when a car lacks suitable ISOFIX anchors or a family needs a belt-installed seat across harness and booster stages. It starts at the post-infant stage—around 15 months and 76 cm—not at birth. The benefit is broader vehicle compatibility; the tradeoff is that installation quality depends on following the vehicle-belt path exactly and removing slack each time the setup changes. Before buying, check that the belt is long enough, the buckle does not sit against the shell, and the headrest can rise without meeting the vehicle roof or head restraint. Revisit the supplied instructions when moving from the internal harness to booster mode rather than treating 100 cm alone as the whole decision.
