@fatgirlslimmer I would be too wedged in 
So. It turns out, lift and pivot does work. Hurray. But not quite. As it seems the wall isn’t straight. So even though it measures 196 across at measuring height, and the skirting boards are not very thick at all, it is about half a cm too narrow at the base with the skirting boards as they are. Grrr. So I am now going to have to get some wood to lift the ends of the bed up 6cm so they can stand just above the skirting board. I don’t want to mess with the skirting board as afraid it will necessitate replastering.
