How to differentiate between "On Top" and "Above" If I wanted to translate the prepositional phrase "on the bed" to Chinese, I know to say "床上", but I don't know what the translation would be for saying "above/over the bed".

From what I can gather, 上 is used for both "on" and "over". Is there another word that removes the ambiguity, or some modifier?
"above/over the bed" can be translated as "在床的上面" or "在床的上方" without any ambiguity.
