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?
