The third idea was to use a circle of 3/4" plywood with astroturf and
6 side brace points on one side and a 27(?)-point cell on the other.  Any

I don't think you have to get this fancy.  You should run PLOP to get a
feel for what back support is necessary.  For the edge, a sling or slippery
points at 90 degree separation will be fine.
