Whether this was a trend your grandma followed in her home, or maybe one of your friend’s families did, putting plastic on the couch is incredibly tacky, plain and simple. It was one trend that should have never been a thing honestly. There’s nothing that portrays feeling unwanted in someone’s home more than sitting down on a couch that crinkles in the only way plastic can. If you still have plastic on your couch, not only will everyone know you’re old, you’ll also be telling visitors that you don’t trust them sitting on your furniture, or anywhere else in your house really.
