I'm getting ready to make a King Size bed frame with storage. For weight/transport convenience, I am going to construct from a series of sub-frames made with 3x3/4 birch ply. Subframes at right angles to one another will be fastened with pocket hole joinery. The material-conservative way would be to cut individual stiles and rails and fasten with pocket holes, but that is labor intensive. The less-labor-more-sheets-of-plywood way would be to rout out all the openings making each subpanel a single piece. Is there any consideration that suggests one approach over the other??
