Review: It works great - I’m amazed. Didn’t know these exist. Previously used chair pads that were too small and too either thin or thick. Ive kept my sofa in good shape but the sagging side where I always sit bothered me so. This makes it look brand new. Don’t hesitate to order this product.
Review: Kept me from buying a new couch. - worth it. I was thinking of getting a new couch because the cushions were bothering me so much, but as soon as I put these in it felt a lot better. My cushions have a zipper, so I just put them in between the existing foam centered in the middle where we usually sit, and my couch honestly feels new now

### ⭐⭐⭐⭐⭐ Saved me from buying new couch!
*by C***T on July 8, 2025*

Second time buyer! I have a huge sectional couch that has seen it's fair share of love. Dreading buying a brand new couch, I stumbled across these. They work so well that I bought a second set so every cushion in my sectional has additional support. Easy to use and you basically set them in place and forget they're there. I'd recommend.
