The standard solution - which we plan to employ - is to use lightweight
stiff foam (coloured white) or high density chipfoam (heavy) to provide the
seat contours - raised sides, bolstered lower back- and put a layer of
temperfoam over it before covering.
Temperfoam slowly contours itself to your shape so you don't get pressure
points on your ***, and is "G" sensitive - a fast application of G makes it
go stiff. Used in the Shuttle seats and some ejection seats. V. expensive,
available from Spruce, RD Aviation, etc, but well worth the expense.
