Ideas to have a bed when needed without using a sleeper sofa for seats

I have a small 2 bedroom cabin. A queen bed for the rare overnight guests fills the 2nd BR. I am wanting a way to make that room a useable space, like a den, but I still need a bed occasionally. A daybed is too small; and there is no place to move chairs out of the way if made a murphy bed. There is only one useable large wall due to inside opening french doors, a sliding barn-door style bathroom door, and a closet on each of the other walls.
The one uninterrupted wall. on the left of the cedar wardrobe is the entry door; the bedside table is in a corner.
View of bathroom door when closed, slides back to the left. The French doors are at foot of bed.
