the kind of beds where there is another bed under one bed but you have to slide it for it to come up? its not a bunk bed
A trundle bed or a captains bed.
Oh, I love a puzzle. Are you talking about a hide a bed?? Sometimes people use them on a day bed frame and then pull them out for company. Or are you talking about a Murphy bed, which actually goes up into a wall and looks like a piece of the wall? I think it may be one or the other.
