I had a proper struggle with my saloon rear seat. The latches were mis-aligned and in trying to 'persuade' them to work, one side got jammed. When I finally got everything released, I noticed some white plastic had disintegrated on the lower rear pivot joints where the backrest hinges on the floor pan. This meant in my case the backrest had dropped just enough to throw it out. I honestly can't remember what I did to fix it, but it took some time and patience. On the odd rare occasion when I need to drop the backrest, I take particular care to baby the mechanism
