This is for a combination guest room and study.
We do have another room with a king size bed which can be used by couples visiting, but the intention is that this would be a daybed kind of structure in a small study, used occasionally when a single person staying, maybe at short notice.
They are normal length but 75cm wide rather than a normal single which is 90cm. I could fit a normal one in, but it's then quite cramped in the room, and the main use is a study.
At first I thought it would be too small for a large adult, but actually it's half of a king-size bed, so perhaps it's fine? Any experiences?
