## Questions & Answers

**Q: When i took my cushions off and measured the dimensions mine ready 25” x 72”. Do you all something that will fit that?**
A: I ended up buying 1x3 lumber and having cut to size at the store

**Q: Could this be shortened to 63" width?**
A: You can shorten it by folding panels on top of each other.  See the photo that shows they can be folder on top of each other like an accordion.

**Q: Can you adjust the length?  Are you able to remove a board from pocket to shorten if needed?**
A: Yes.  I was able to remove boards just by cutting one end of the pocket and sliding it out.  I also cut mine in half to use under chair cushions.

**Q: Can you adjust the 67 inch size to fit a 63" long sofa?**
A: If you can you can try to push it down 2 inches on side of sofa on each side. Also is easy enough to cut with a saw. But its up to you on what you decide to fix it to fit. Sorry I hope this helps.

### ⭐⭐⭐⭐⭐ 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.
