I have been busy rebuilding and re-trimming the front seats on my 4cv. I have one finished... finally. As with most tasks, it took a lot longer than I expected.
The driver side seat frame was bent, most likely from a heavy person sitting in the seat when the car was hit in the back. I had to cut the frame in four places to get it straight, then welded it back together.
The lower cushion consists of a layer of jute backed by burlap, about 25mm of horsehair pad, and another 25mm of cotton batting. The seat back has a very strong burlap material stretched over the tubes. There are "border wires" on each side added after the burlap was installed. These are not present on all 4cv seats, but all the USA spec 4cvs I have seen came with these seats. The border wires are wrapped in jute and cotton batting to give the seat back a more scooped profile. It is probably to help keep the driver in the seat during spirited motoring - especially considering the amazing 28hp of the US spec 4cvs.
I will post more pictures soon.
