Hello I’ve already read a lot in your forum, but I seem to be too stupid: I would like to transport a 2m PAX cabinet from the Ikea with my C30 (2012 summum). I would like to do this as I often see the passenger seat in the forum, but I can’t do that. Can’t I do that with this model? Or do I just don’t find the function? Setting back in “sleep position” is possible, but then the headrest would be in the way… Thanks already for input!
