First step was to clean and brighten with GOOP hand cleaner. Lifted all the gray out of the krinkle. Added wire to tie together all the sinuous springs and added coil springs beneath for added support. Made for a very stiff platform.
Shaped some base high density foam (2.8/45) to make the sides flush with the rest of the springs. Transfer the burlap loom wires to the new burlap, which is essentially doubled for good backing.
Here's the original tag inside the seat cover, and the 2" high density base foam and 1" latex foam that tops it.
Here's the over-stuffed result--round, firm and soft. The real differences from factory are the paper-wrapped wires connecting each sinuous spring, which makes for a very stiff base, and the way the foam is finished. Factory foam overlaps the top frame for padding behind the apron/around the drop edges, but with 2" base foam this isn't possible. Instead, we put a 3.5" strip of the 1" latex behind the cover apron.

Nice job, thanks for posting how you went about doing it.
Only other tip that needs mentioning is using plastic zip ties to lace it up first, before trying with hog rings. That, and we heated the vinyl to make sure to get its maximum stretch. Backrest was a surprise--it's all cotton batting and no foam and you can see what a moisture sponge this was.
edit The covers are padded but have spots that are not padded. The bench needed added spots (under thigh) to avoid puckering. To prevent this we had to section the latex in the backrest.
