into the back of a 2+2, and have use of the seat infront of it. Even forward facing car-seats are difficult, because they raise the seating position up and forward. I used to use a 5-point harness pad, don't see it as avaialable anymore, as my kids were already forward facing when I put them in the back of my 2+2. Thouh there do seem to be other somewhat similar options available these days.
