We bought a rolled-arm Pearce sectional from Pottery Barn in Florida...so it has to be close to 20 years old at this point. It's crossed the Atlantic twice, and been in seven houses since. Not leather, I believe it's ultrasuede, but nothing will stain it and it doesn't sag. PB should be sending us royalty checks, I think at least four friends have purchased them since spending time on ours.
We relaxed the no-dog rule about three years ago, mostly because I think wifey wanted to damage it because she's "tired" of it and wants a replacement. Even they haven't put a dent in it...all their fur, drool and zoomies haven't done a thing, it all wipes off. And they're seriously comfortable. I can't vouch for their lower end stuff, but the higher end is definitely well made.
