DS2 has just moved to a small studio flat. Presently sleeping on camping mats but as he has to be alert for work in the morning, that can't go on for much longer. I'd like to help him with the cost of a futon or sofa bed or some such - nothing too big as his studio room isn't huge and it's up a flight of stairs. Nothing too pricey either - neither of us has a lot. He's there for 6 months so something ideal for eg a sleep over might not be appropriate.
Would a futon or sofa bed be preferable? I've no experience of either. If anyone's got experience or recommendations, I'd be pleased to hear!
