Seems like Dan has maybe hit closest to the target. At least there's the word cabinet in the name. I did a little looking. I'd be skeptical of finding a plan for that bed but I doubt it would be hard to reverse engineer it.
I'll try again to make an answer less hard for you to describe. You've said "a cabinet bed" twice but haven't said what is your description of "a cabinet bed". Do you have any pictures of what you'd like? Other folks who've responded to your post have asked the same question and you haven't answered any of us with anything useful.
