These are a great concept, but fall off and get wrinkled easily.

I have three cats, but only one of them loves to claw at our sofa. We got a brand new sofa a few months ago and it's a constant battle to prevent scratching. Scratching post don't even satisfy her as much as a good scratch on our sofa. Anywho I gave these a try and I do like them, but they do wrinkle easily. I also have parts that don't seem to watch to stick right. Overall, though they do protect well.
