Thanks for your feedback. After looking into foam and lying awake in bed trying to figure out what to do, I decided to figure out a way to support the broken springs. When looking at the seat structure, I became amazed at what must have gone into making these seats. And it looks difficult to take the spring structure apart or put it together. I had some 1/8 by 1" flat bar that I slid under the spring. The breaks were were between two of the "coil towers" so I bridged between the two and supporting the broken one in the middle. Then I used re-bar wire and cross wired the center of where the flat bar met the spring rods. I did this for six of the coil spring towers (three in each line). As a result, the support now matches the rest of the seat (i.e. the movement in the broken spring area is minimalized when pushing on the spring from underneath). Hopefully the pics will show it better than I explained it! By the way, I am going to place 1 inch foam over the horsehair before installing the seat upholstery. Any suggestions in regards to fitting the foam? That is, should I trim it to follow the seat edge or should I allow for some over lap to wrap around the spring frame?
It's a small world, but I wouldn't want to paint it.
