As noted, yes the spring used no wood and had wires that dropped into two holes in the riser.

Now based on other responses some clarifications are needed. The majority of models indeed incorporated hardwood frames below or behind the springs for the covers to be tacked to. However this did NOT apply to Roadsters, four door Phaetons, and Open/Closed Cabs (truck and pickup cabs). These models used springs with a special channel at the base. The covers were made to absolute size with a welt sewn into the bottom edge of the cover. This formed a bead which the special channel contained when crimped closed.

As with most other parts of the Model A, Ford made seat covers for most models available through the dealer's parts departments. However the crimped design described was not considered 'serviceable' so if you damaged a seat cover in a Roadster for example, a replacement was only offered as a completed seat cushion assembly.

With all that said, you will find very few cars with the covers made and installed like original. The typical method is to make the cover facings at least two inches longer to be wrapped around the bottom of the spring and attached to spring coils with hog rings as noted in other responses. This allows for the cover to be installed without special equipment and provides much needed adjustment to compensate for manufacturing inaccuracies.

The first pic below shows original '29 Open/Closed Cab cushions. The other pics show '28 Phaeton cushions I did about fifteen years ago for the late Dave Lopes.
