We have a sofa bed but it's rubbish- fine for a single person but 2 roll together. We have 2 single beds (the DSs), one of which has another spare mattress beneath it. I fantasise about having one of those beds where the the under-bed slots up beside the normal single to make one double but they're about £500! I suggested to DH that we 'make' a truckle bed from a single slat base (always available at our local dump) but we'd have to make it a bit shorter and hope we can pull the normal sized mattress that would sit on top of it through the legs of the existing single, pine bed, but he thinks it's too much hassle
Although we don't have guests that often (3 or 4 times a year), this is gradually increasing and I feel we just cobble solutions together rather than being able to do it properly.
What do you do?
