Murphy beds have their place, but I don't care a lot for them. Too much bed making for my taste. But if you needed to conceal the bed, it would work. But my version would be a bed that raised up to the ceiling during the day, then have somthing under it, dinette, or whatever. Then when you wanted to sleep, lower the bed, and climb in. And when you raise it you can just leave it messy, and not worry about where the blankets are sliding et al. Some of these blend with the ceiling, so no one that doesn't know will even know it is up there.
As far as hardware, I'd just figure out what I needed, go to the hardwars store, buy it, and go from there. I'm pretty sure the early Murphy beds didn't use a kit to make them.

.....Call me a craftsman, artisan, or artistic, and I will accept that. Call me an artist and you will likely get a quite rude comment in return. I am not a @#$%ing artist.
