I thought you couldnt have the main seat facing in to you with the second seat in use unless it is the capsule?
Only just saw this post - I don't think they mention it in the instruction manual, but I have seen pics on the net of people having the top seat rearward facing with the second seat on. I've given it a go, and it doesn't fit if you're using the seat adjusters. Also,it would probably only work with a smallish baby, as to give the toddler more room, it looks like you've got to have the footrest up a fair way.
