I can't answer your question directly, but on my build (which is an over-sized) I bought a large one and cut it down. It's put together with strips of corrugated steel which then has rods put through it and nuts attached. To cut it down, I removed the aluminum frame, pulled the rods back to the point I could remove strips to get my length. Then I cut it down with shears to get my width. Finally I removed each rod, cut it, and then using my die set, rethreaded the end and put the nut back on. A Lot of work, but makes for a nice bed. Being steel it also means I can use magnets to hold down warped or light materials.
