Advice on constructing a timber framed base for a breakfast

[Deansplit]

I want to make a breakfast bar which has a 1500mm ash top, which is partly overlapped by the end of the kitchen worktop. The base needs to be eventually a sheet of stainless steel (purely cosmetic) which literally wraps around whatever load bearing frame is supporting the top.

How's the best way to make this – I presume some sort of thick plywood circular base fixed to the floor (concrete) to establish the diameter, with multiple studs fixed to it vertically? But a presume a few diagonals will be required to prevent it from twisting of tipping sideways?

Check out bendy ply, wrapped around curved shelves top bottom and middle

Well it'll be 600mm or less on diameter than the top.

I think definitely the curved shelf type approach is good, maybe with a full circle 3/4 or inch ply as a base to keep the bottom true. Thinking the main frame could be 2x rectangular pieces of ply (cut to h x dia) and 2x halfway central slots cut into each then interlock them to form a cross?
