Specifically T-legs, in the style of the older cocktail cabs.
I ended up buying the Bekant underframe, as it's seriously one of the few that I could find with a T-shaped base.
Now, it is a bit long at 120cm, so with a bit of help from my dad (he is the one with all the more expensive and useful tools), I hope to reduce that length to around 76cm. And the reason: including the thickness of the MDF at 16mm, that will make the overall length around 79.2cm:

If all works out, I'll have a solid, stable frame in which I can essentially build a "box" around it. That's the theory anyway.
Plus it's an opportunity to include my dad in my own nerdiness.
