I'd be really grateful if you could recommend me a folding / fold away bed please. We have a downstairs room which needs to be an office most if the time, but also a single bedroom for DS1 when he's home from uni. But that can be for 3 months over the summer, so has to be really comfortable. Not sure whether a Zedbed or a single that folds against a wall would be better. Im bewildered by the choice so a recommendatin would be great. Thanks.
