Maybe Denny will post his experience and suggestions. I recall he has taken very good photos of his seat cushion "restoration".
I think he tried to reproduce the layers of materials and type of materials that were originally used.
Jim Carter sells an installation kit, but I found it to be too soft (cotton batting and burlap) - the tops of the spring coils could be felt and seen. JC's kit includes original-style barrel clips, rather than hog-rings.
A good addition would be layer a short-nap heavy-duty carpet material
It would also be nice to hear from someone who used the LMC kit. It might be better than JC's kit, depending on the density of the "foam seat" and the strength/thickness of the "reinforcement material". This kit has hog-rings.
Here is a grainy-illustration of the
layers in an original A-D (1954) seat cushion. You want to make sure the top layer goes over/beyond all the upper perimeter of the seat-spring.
