We need to buy a high back booster for our child who is now appropriate age/height/weight for it. We do have a rather small, 3 door car, so something compact would be the best. After a bit of research the Maxi Cosi Rodifix Pro2 ticked all the boxes and seemed like a good fit. However, just checked the ADAC testing and it only scores as "satisfactory" in safety tests... Does it rule it out?.. What would be an alternative? Cybex Solution ones seem to be much bigger/wider. Maybe Britax Kidfix? Anything else I'm missing?
