Got these bc my adorable sassy puppy likes to put her balls under the couch and i was having to get them out every 5 minutes. She's smart so she was most likely getting a great deal of joy having mommy fetch her ball for her. These are a godsend. Work fantastically. Well made. And they come in individual sections so you can customize the size to your furniture. And you get a generous amount. I have a big couch and did not need all of the sections.
