I've given up on moving the bed on my own. It has a heavy base and has to be lifted into exactly the right position to lock in place on the bedends, which I don't think I have the muscle for. If DS drops in this afternoon he will find a job waiting for him.
I've dismantled the KS one and stored it up on its side leaning on the wardrobe, with the mattress (Dunlopillo and very floppy and unmanageable) stowed in behind it, so no acess to the wardrobe. I've moved the bedside tables from either side of the double bed to where that bed WILL be eventually, so if DS doesn't drop in I shall sleep tonight with no bedside table for my specs, mobile, box of tissues etc etc.
The plastic crates from under the double bed are stacked in the bath, the only spare space left in the house. Just as well there is a separate shower. I might raise the enthusiasm to go through the contents later this afternoon and weed out some of them.
