Bought as a spare seat for grandma. Here he met fully its purpose. For long trips, I would not recommend this seat. Our son now 13Monate (75cm and 11kg) has not much grip in the seat (seat is still too wide, headrest in the deepest postition too high). The fixing is without ISOFIX course not as stable. For children of group II and III it is certainly much better suited, but perfectly adequate as a spare seat. Material, price and Servic very good.
