in our old place that was a 2 bed terrace we had had a king furniture sofa bed thingy. so when guests werent staying we had a nice lounge set in the formal lounge room. it could be both a queen size bed or two singles which was super convenient. and we also had a spare single mattress.

in our new place it is 5 bedrooms and we now have a spare queen bed in a guest room and a single bed in the study.
