What you need is the column type of stand. These are quite rare but they still produce and sell them. Check out Quantum Core by On Stage Stands for instance.
I work in a hospital now and I see lots of heavy gear on mono stands (usually on wheels).
Maybe check out medical equipment? Find out where they get their stuff, or raid an old hospital.
I have one by Ultimate, barely used, 3/4 tiers (can’t remember), i wanna get rid of. They are great. You can put two of the tiers inside the column. Has a weight but quite portable.
Ultimate is good, but still quite not as simple and compact as this one. This could work really well in situations where you need to fit 2 - 3 levels of drum machines or light keyboards one above another.
