We're about to move into a small flat and think it would be the best space saving solution for DP and I to use a sofa bed in the living room for our permanent use. Bit wary about having to open it out and collapse it every day, and I'm a bit worried about comfort as I do have a tendency to back pain, but we can't think of a better way to use the space. Anyone else doing this already? Any favourite sofa beds that have proven to be comfy and easy to use?
