I'm currently using this on my sofas (2). They are wide enough to completely cover the entire seating area (76-80 inches) .  They do slip a little but are easily straightened. My only disappointment is the sable color I wanted was not in stock and I ordered the ivory - which is just too light for my taste. I will order the sable once/if they are back in stock and use these as covers for the beds when my family brings their fur babies.
