Finding the right preposition is always tricky for non-native speakers of English. I'd like to know what native speakers think of these two versions:
(1) He was born on a bed.
(2) He was born in a bed.
Here, the "bed" is not a figurative bed but simply a piece of furniture for sleep or rest, typically a framework with a mattress and coverings.
Are both idiomatic and natural to native speakers?
Or is one more idiomatic and natural than the other?
