I went through this 8 years ago, thought I did my research and got hustled by Palliser furniture.
Recently found the light, and that is to buy or build the retro designs with exposed hardwood that uses cushions. I bought a sweet Danish designed loveseat recently, it doesn't take up half the room, and I can move it solo if need be. The beauty of cushions is that they can simply be replaced. When the time comes, I'll have these made out of goatskin. Goat is cheap, tough, and plentiful- look at all the WW2 A-2 flight jacket styles made from them. Yes I know the originals ones were horse. Tandy Leather is chock full of goat, but I'll likely just source from a middle east tannery direct.
The bonded leather that manufacturers sneak into areas of the couch will disbond & flake off after 5 years, everyone lies about what their leather really is, and these MF'ers are lyin' ass bitches to deal with. Buy vintage off ebay/craigslist etc & go for a reupholster in full grain leather is my take.
