### ⭐⭐⭐⭐⭐ Couch cushion
*by C***O on January 26, 2026*

Worked awesome on the sofa. Made it feel like a solid sofa and when you sit it holds you up. We used it on a sofa bed. This is an awesome product to have

### ⭐⭐⭐⭐⭐ Works perfectly
*by A***R on December 28, 2025*

This is a really great product. Fit perfectly on my couch and the support it provides is fantastic! It's a night and day difference!

### ⭐⭐⭐⭐ Works well for old couches you still love!
*by A***A on December 5, 2025*

This works great for the couch that puts my husband to sleep within 10 minutes anytime he lays down on it. It fit perfectly, of course I measured first. It adds support and has pretty much ensured that the couch will be around until the end of time. It's worth it if there's a couch you just can't be parted with. My husband is happy, that makes me happy. I didn't give it 5 stars because the cushions do slide off a little, but not a lot, it's not a big deal.
