## Description

Product description

Review: Better Than I Expected It Really Works!!! - I was honestly skeptical before buying this, but I’m shocked at how well it actually works. My couch cushions were sinking in the middle and starting to feel really uncomfortable. As soon as I put this underneath, it made a noticeable difference right away—the cushions feel much firmer and more supportive. Installation took maybe a couple minutes, nothing complicated at all. It’s also sturdy enough that it doesn’t slide around once it’s in place. It’s not going to make your couch feel brand new, but it definitely improves it a lot and makes it comfortable again. For the price, this is 100% worth it and way cheaper than replacing a couch. I wish I bought it sooner.
Review: Perfect fit and support! - Great product. It’s rare to find something that fits a long, formal sofa so perfectly without needing adjustments. It gives my vintage piece exactly the stability and support it was missing. Simple to use and exactly as described—no extra boards required.

## 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.

### ⭐⭐⭐⭐ Worth the purchase
*by M***. on March 3, 2026*

Seem to be working good. They are a good size furniture and the material will be easy to clean. My only complaint is that my cushions slide off the material very easily which is likely an easy fix with some Velcro strips
