Kiddy 41430IP071 - Kiddy Infinity Pro car seat ECE class 1 from 9 months - 3,5 years (9 - 18 kg) We have now acquired this seat even for our second son and are very satisfied. He can be in no time by a car lift to the other, what is just, if it is to go fast very beneficial. Both guys had to get used to the impact cushion, after a little while but was no longer an issue. In order to prevent "slip" under the impact cushion (only as a precaution), brought and we take the seat at the beginning of the journey in the reclining position, of course, only right after the transition from the infant carrier. Thus the conversion of the children does not fall so hard. With about a year left and we let the children then sit properly, but they no longer even slide down. More decision support were consistently good test results for us. Overall, in my view, an all-around good fit.
