It depends on your personal aesthetic. We bought a couple of new heavy duty, chocolate colored moving blankets ($14 ea) and use them as both a floor cover (dirty feet) and a couch cover when the pets are along. I added four strips of elastic to the corners of one blanket to ensure it stays in place on the couch. The large size I found fits the couch in either the seat or bed configuration. We like the fact that we can throw the blankets in the wash whenever necessary or at the end of each trip.
