-1 star because washing instructions say "line dry." I took a chance and put them in the dryer on extra low heat for an hour, and they came out beautifully. I think they might have shrunk ever so slightly, but they still fit my couches well. They stay put, even with two dogs jumping on and off them all day. We just cut the strings off the back - they adhere to our fabric sofas well enough without needing to be tied down. Not waterproof, but thick enough to block the normal dog slobber, and they kept a drink my husband spilled from bleeding through onto the sofa underneath. I might order a few more, so I can rotate them on laundry day. They are also nice and soft.
