IKEA makes a folding bed, Sandvika. It has four cross-braces for the center legs, made out of cheap aluminum with stamped rib - these have a tendency to bend and break, and you can't buy a replacement.

It is likely trivial to make a metal replacement if you have some metal strips and a drill press, but I don't, so I took a couple measurements and printed some plastic braces. They are 10mm thick for extra beefiness, I printed with 20% gyroid infill ; feel free to make them thinner if you think that is too much. I printed in ABS, but PLA should work as well - they are loaded in stretch direction and the actual force on one brace is not that much, it's the rigidity that matters.

Mine have been installed and serve reliably with many folding bed uses.

I also recommend replacing cheap IKEA nuts with nylock ones, or applying a dab of threadlocker, or nail polish, in a pinch.
