I have an old Ikea bed with this kind of central supports:
The problem is that these central supports are flimsy and tend to fall on the side, and I would like to find a way to secure them. For now, I put a pile of books below it, and it's still unsteady.
The height of the supports is 23cm.
I looked for better solutions (apart from changing the bed). I've tried a few approaches, including supporting it with car jacks.
.
These jacks are ugly and generally too tall (28cm+), so I also attempted to support it with bed risers.
:
These tend to be too low and not adjustable (15-20cm max).
How can I secure the central support, or support it in an adjustable way?

The existing supports look to just be a piece of wood stood on end, and fastened into the rail running the length of the bed. The simplest solution would be to build a wider support, also out of wood, and also fastened into that rail. Grab a 2x4, cut it into pieces ~6" long, and stack them until you get the height you need. 6 lengths of 2x4 stacked in this manner should get you the 23cm you need (a 2x4 laying down is only 1.5" thick, and 23cm is 9"). Screw or glue them all together and you're good to go. Orient them perpendicular to the rail for additional stability.
A single 8' 2x4 typically seen at the home centers will cost about $2 or $3 (in the US, at least), and a box of screws a few more dollars, making this a very cheap solution.
