Review: Couch is like new again! - Nice and firm cushion replacement. Need to open it and let it sit for 3-4 days before using. Cuts easy, I just used a razor knife with new blade.
Review: We are happy couch potatoes! - Great quality - I ordered this foam piece as a replacement for cushions that my dog chewed up as a puppy. Now, that same puppy is a 3 year old beagle, and it quickly became his favorite napping spot! The foam is super firm - ideal for extending the value of my investment. Because I am lazy, making a sofa “bench,” the project was easier, added stability and functionality (and few opportunities for chewing). Though I would have preferred double thickness, I simply ordered another foam piece and it gave me the thickness I desired. My dog and I are happy couch potatoes!

### ⭐⭐⭐⭐⭐ I finally have a comfortable couch!
*by D***E on November 19, 2025*

When we bought our sectional couch we liked the look and didn't spend much time sitting in it. After using it for a while we hated the overly soft cushions and felt like we were sinking in them. We started shopping for a replacement because it was too poofy. Luckily, the cushions have zippers so we were able to remove the foam and Dacron liner. The Dacron came off easily and we replaced the foam with this solid version. It was easy to cut with a bread knife, we used spray glue to put the Dacron liner around the foam and now our couch is solid and comfortable. We have recommended this foam to our friends who also replaced their poofy cushions.
