I don't know...my living room set (couch, love seat and recliner) are all light tan genuine suede. They were stain guarded at time of purchase six years ago and there isn't a single spot on them, despite many spills. There was even an ink pen incident and it came right out.
I guess I was asking because some people actually think Alcantara is real animal hide. Some guy on the Volvo forum insisted that it was alpaca suede.

Again, great work Christian!
