Works for me!  I purchased the covers to just cover the main surface of my couch so the dogs don't abuse it too much.  They worked out just fine.  The quality seems to be okay, with the exception that they're not waterproof.  I haven't washed them yet (I actually have one sitting in the laundry room right now waiting to be washed), but they seem to be sewn together well and I really don't foresee any problems.  They're a little shorter than my furniture and they don't quite cover the entire sitting surface, but honestly they're working out just fine for what I needed.
