Fold out bed/dining table construction tips for a ttt?

We recently bought a 1979 Sunlight Sunspot that is completely stripped inside. (Check out our album, we're documenting progress as we go.)
We want to build seats that fold out into a bed with a dinette table in between. I have looked high and low for plans, information, videos, etc, but am coming up empty handed. I have a basic idea in my head, but would love some input from you folks. I don't need help with the seat cushion/bed mattress - we can figure that out.
My concern is how to build seat bases that in combination with a dinette table turn magically into a full size bed. I'm interested in any an all options and ideas, including how to anchor a table to the floor, how to support the fully extended mattress frame (probably 3/4 plywood) in the middle, how to set seats up for convenient storage, that sort of stuff.
Feel free to throw me ideas, pics, drawings, videos, anything that could help me not re-invent the wheel! Thank you in advance for the assistance.
