I'll add my voice to those saying plywood and firm cushions. Most sofas are
far softer than most people have any need for -- it's sort of a contest for
who can provide the most travel in the springs and cushions regardless of
whether it's useful. My favorite sofas are made to begin with using solid
foam cushions over wood slats or solid wood. My butt provides ample
additional padding if needed.
Lift the sofa cushions. Some thin plywood (3/8) under the cushion
will give support if affixed properly.
An upholstery will cost you some dollars, even if you change the couch
Springs stretch. I sat once on a unit, the person, when I mentioned
broken springs, said .... but it "looks good"!
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.
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.

MCP, I'm serious. Ask them *why* they do not want to replace it first.
I'd be really royally pissed if some well meaning relative came in and
insisted on putting plywood on mine so it no longer dipped just right for my
back needs. In fact I'd stop them unless they snuck in and did it 'as a
suprise favor' in which case I'd be changing all locks then praying we could
fix it back.
If the only reason they havent adapted it is financial solvency, they may
appreciate your help. If it's some other reason, you tred dangerous ground
if you do not ask them 'why'.
I have never owned a couch, I use chairs (not sure why folks buy
couches--makes no sense at all in MY home). If the springs are worn
its my guess the fabric is very worn too. Inspect the couch
carefully for damage in the frame and springs. You can cut a 1/8" ply
or particle board to fit under the cushions for support. Also,
consider raising the entire couch 2" by adding block feet under the
existing legs. You may consider adding a fifth leg to support the
center of the seating area, especially if the couch is long or deep. A
slightly higher seat may make it easier for elderly or handicapped.
