Nice surprise, this item holds up well

My mother's couch was sagging in the middle, but she still liked the couch so we purchased this Shinnwa Couch Cushion Support for her about 4 months ago. I asked her how it was holding up the other day and she said it is working out great! She put the support under the middle cushion on her couch so you can't see it and now she can sit on the couch with firm support. Honestly I was expecting her to say that after 4 months it was flat and didn't hold up, but gladly that was not the case. She said it was the right choice for extending the life of her couch. The item arrived quickly and was well packaged.
