I have a quite old recliner that is sitting really low now. I believe something has broken. One day i noticed one side sitting low a few days later the other side dropped down. It sits so low I can't raise the leg extension. I can't seem to see anything that's broken. All the springs are in good shape. Any ideas on what broke?

I've tried turning it over and looking at it and can't seem to see what is broken. Any other ideas?
