I haven't been around much lately, but I found a way to do it for the feet of the futon just recently. they're square peg legs about as thick as a fence post, so I bought two post base brackets for the front legs to sit in, screwed them to the floor and they fit perfectly.
Now I just need to build some sort of quick release mechanism to hold the futon to the floor since it sits in the base unattached. This way, I can lift it out of the base and lay it flat as a bed, when not in couch mode.
