For some reason the front seats were in good shape but the rear seat was not. Mice had gotten to it, and although it looked ok at first glance, it was really in pretty bad shape. I decided to try reupholstering it.
The first step was taking lots if pictures to document how it was put together.
Then it was time to strip the old stuff off and clean up the frame. Luckily there were no broken springs or other significant damage. I wire-brushed the frame and gave it a quick coat of paint. The paint is mostly to make it a little nicer to work on.
