Review on 21''X 16'' Sagging Couch Support Under Cushion Sofa Seat Saver Fordable Board by Mark Meyer

I had my doubt as to whether these supports would provide in my sagging 3-year old couch cushions. I bought three of them, one for each of my couch cushions. They easily slip in between the couch and the cushion. After three week's of using the couch daily, I am pleasantly surprised to report that while sitting in my couch, they support my hips and low back minimizing any discomfort I was feeling prior to having them. While they don't change the sagging cushion per say, they do change my experience in sitting on my couch. For this reason, 5-stars makes sense.
