Good to know jrowan, wow, that is a very high price for cushion replacement...but if it really is a full set,......well, that's alot also!
Regarding not pursuing the original fabric, I disagree completely. We have the same fabric that Zommer described and they are really in great condition (we have a 1988) and really comfortable, soft, warm, not hot, etc. I know sunbrella fabric is nice, we have it on our outside cushions, but for inside, the original ones are my preference and will last and last if taken care of. I have seen links to that particular fabric on this site so Zommer continue searching, you will find it, and it will be worth it if you need some to add to what you have. I would be doing that if in your position. No disrespect to your new interior Jrowan, just like what we have very much.
