Updating on my situation, my couch is 64" but most of the replacements from Thomas Payne I see are either 62" or 68". I ended up ordering one off of Amazon that is 62" figuring it's just 2" inches, but when I got the couch the sleeping area of the pull-out is 5" smaller in width. This will not work, two adults could no longer sleep there.
Now I'm back to recovering the original and will send the one from Amazon back. I'm waiting on some fabric samples from
https://rvfabric.com/ that from what I gather looks like they are in the same area that Winnies are made and may be the match in fabric as well. Their prices seem pretty reasonable. The couch will be made more "simple" to keep costs down. Less fancy stitching, elimination of some arm-rest pillows. Labor so far is around $600-$700.
But both of the upholsterers I had look at the couch suggested perhaps going with a more durable fabric, one even suggesting marine grade stuff. Micro-fiber and suede was also mentioned. I'm probably going to stick with the original but still debating.
