## Description

Product description

Review: Worked perfectly for more support under couch cushions - We got these to help my elderly parent get support when trying to stand up from the couch. Her cushions were very flat and after placing three of these under her couch cushion it made a huge difference. Think of it like a raised recliner but without spending a ton of money. They come tightly rolled and you need to let them expand a full day before using them. Perfect thickness and they have a beveled edge on two sides. Great value for the money!
Review: My Vintage Sofa Is As Comfortable Today As It Was New! - Love these cushions & wish I'd found them years ago! My vintage 3-seat sofa is as comfortable today, as it was new! No more sagging seats that are difficult to rise from. I'm very impressed with the difference these thin cushions made, since they do not expand very much. The sofa feels much firmer overall & is comfortable to lay on. Highly recommend.

### ⭐⭐⭐⭐ Very firm support. Works well.
*by D***Y on October 5, 2025*

I love this cushion, the wife hated it. She thought it was too firm, but it was just right for me. Our couch was sagging where I sat all the time so it helps bring it back to life. It’s designed to go under the cushion, but on our couch the cushions are built in, but we used furniture covers because of our pets so it works fine. Doesn’t slip around. I would buy it again.
