What is the name of a bed that is in a closet?

So not like the pull down beds...but rather a open closet that is used for storing clothes or shoes but has a full bed inside of it... it is hard to explain but I;ve seen it in some lavish Mideastern homes, and I think some bohemian homes as well.

I am curious about what its called so that I know how to make one, I am trying to make a small bedroom have more space by taking the bed out of it and moving the bed into the closet space, I would still have space for all of the clothes etc with the dressers so closet space is not really needed for storage, but also the bed is the one furniture item that cuts into the middle of the room slightly thus ruining the "openness".
