We have a spare room that is used an office but will also be a guest room.
I'd like a trundle/sofa/day bed which doesn't take up too much room but looks attractive when not in use.
However I'm not sure if I should go for a standard single that converts to a double or a bed that can be a single/2 singles/double and I want it to look like a sofa of sorts when not in use.
What would be more practical/attractive/space-saving? Any recommendations? I don't want to spend more than £350.
Ikea have Utaker which are stacking single beds that can be used as 1 or 2 singles or a double but is not that attractive when stacked. I suppose I could paint them 
or Fyresdal which is a (IMO) quite attractive single day bed but can only convert to a double.
All advice appreciated!
