Pros / Cons
Pros

Lionelo Luuk i-Size is a narrowly useful 125-150 cm booster: its compact, backless shell is easy to keep as a spare or move to another compatible car. The child is restrained by the vehicle’s three-point belt, with the lap section routed low through the guide beneath the armrest.
That convenience is the compromise. There is no back, head support, or side structure, and Dutch road-safety guidance prefers a high-back booster. Before every trip, check the vehicle manual, head-restraint position, low lap-belt path, and that the shoulder belt clears the neck and cannot slip off. If the child slouches or sleeps out of position, use a high-back booster instead.
