As far as the shape of the setback to clear the spar pins mine has a clear 
curved
hardback which clears the pins and provides a firm base for the foam for the
back. It also offer s a little Lumbar support.

The seat cushion insert is the 'absorbing foam material which is a little hard
after a long flight and I'm looking to try and provide more thigh support to 
take
the pressure off and spread the load a little better.

No idea of the manufacture but I did let the Yorkshire lass at the LAA Rally 
Tent
have a look to see if it helped her seat design.

As far as shaping seats to persons profile I remember once watching a program on
formula one cars and they had the driver sit in a mould while they pumped in
a foam to get the exact shape required - sorry don't have any details other than
that.

there might be an argument to take a plaster moulding of my back, then laying
it up with cloth, then applying a suitable depth of foam to that plug, and
then re-laying more cloth on-top of that. This way you get an insert that has
your upholstery attached that you can drop in, and the plan is to then pack
it out appropriately. Would that be a worthy strategy, or am I thinking too 
much?
It might be a bit limiting for wriggle room I suppose, but as I see it, there
isn't much wiggle room anyway. I'm interested in the bean bag solution, but
I have never sat in one that was initially comfortable, and I don't know how
you could contain the beads such that they didn't migrate. So, any opinions on
my attempts to "redesign the wheel" ? I would love to find a product, a spray
foam, that would go off quickly and then be shapeable. It would be great to
be able to use a spray foam as a template-able materia!
