Thanks for the excellent comments and suggestions everyone. We are going
to try our luck at getting them to replace the couch. It will be an
uphill battle, so if that doesn't pan out, we'll try the plywood.

The springs probably need to be retied, which cannot be done properly
without recovering the sofa.
That is if it is coil springs and not no-sags(zig zag), I doubt seriously
that the springs need to be replaced.
I've never seen a coil spring wear out, unless it was improperly installed
and actually broke.
As others have suggested your first bet is to try a piece of plywood over
the deck under the cushions and raise the base.
Secondly, I would try a firmer core in the cushions.
If it's a quality piece, it would be worth it to fix it.
