@Carolyn Danese, wow--such a radical idea...I like it! :) Mostly because one thing I didn't mention is I am pretty chemically sensitive so new furniture (new foam cushions, fabric, glue, whatever) concerns me quite a bit. But there are two cat-damaged areas (photos below) so I'm not sure what to do about that?
Also, embarrassed to admit: I think we've only flipped these cushions maybe 10 times in 23 years, and that was probably due to moving! So I guess we could start doing that...ha. I also don't think it's been professionally cleaned more than twice. I presume it's a giant dust mite factory now. Eeek!
Bottom line, I'd love to keep as is and save $$, but not sure we want to go another 20 years with these raggedy cat-clawed parts:
That oh so stylish piece of adhesive plastic cured our cat of her sofa scratching habit, but it remains on there because when I started peeling it off, the fabric started tearing. EDIT: the fabric wasn't tearing, exactly but I realized I might as well leave it on since we were going to be reupholstering...some day! :-D
