Studymum, the adapters automatically came with the pram. The previous versions of the strider don't seem to fit it as the clip joins are different. They sell a capsule for the plus which only faces inwards towards you.

I have DD in the bottom seat because it lays flatter than the main seat.
Thanks, I might go to a different store to have a look at it, honestly the woman who was showing it to me was a bit of a no brainer.
