its near the front of the couch,  where the back of the legs go,   i didnt think it could be fixed,  looks like a insurance job

As show by Roger Koh it is possible to fix a large patch on the underside of a damaged bi cast panel but the area discussed on here is not viable and I understand it's also difficult to obtain bi cast panels.

The best option might be to replace all seat panels if a sofa, or just the one if a chair with colour matching leather.

It would probably be less expensive in the longrun and could be regarded as a permanent repair unlike patching and praying.
