Just been to get the dog groomed, put the seats up at the rear so she could lay flat on the floor, she was buckled in via the seat belt connector.
As I was driving I heard a bang at the back of my seat, I pulled over and found that the single rear magic seat had dropped down with an almighty bang, fortunately the dog was lying on the floor on the passenger side.
I fear that if she had been laid on the foot behind me the seat slamming down would have coursed her serious spine injury.
