"Ágyban vagy?"

Translation: Are you in bed?

How would you ask "Are you in the bed?". I imagine you would add "egy" at the beginning if you were asking about "a bed", but not sure about "the bed". Thanks! :)

Are you in the bed? - Az ágyban vagy?

Do you sleep in the same bed? - Egy ágyban alszotok?

"a bed" would make more sense in a different context like this:

We have to buy a bed. - Egy ágyat kell vásárolnunk.
