Hello, the search didn’t really get me any further with my problem. Our child seat “Concord Lift” meanwhile – we had to adjust it accordingly in height to the growth of our daughter – in the middle area of the backrest quite different from the back bench because it is on the headrest. Has someone here tried the child seat “Seat cushion with backrest” from the Volvo accessory range? My dealer doesn’t know if the problem exists there. For many tips already thanks. Michel
