Is yours a dormobile with the cooker under the passenger seat? The brackets are there, looks like they ha e just attached them to the new wrong seat
Behind beneath , the cooker is hidden by the seat, the original fixings are all there, you see on the original seat where the pop rivets or screws have been removed? That's where the brackets that allow the seat to fold attache, they have been attached to the aftermarket seats
I thought all dormobiles had that ? Not sure it's dangerous or at least any more so than any other t2.
