Does such a thing exist?
Our sofa is a 5 year old Ektorp from Ikea, it's been great, and still looks fine actually, but DS dribbles etc on it. The covers are dry cleanable I think .
Is it time to get a new wipe-clean sofa? Are good quality leather sofas immune to small children? I've never been so keen on leather sofas, but if there's one that's resistant to DS I might reconsider.
