## Description

desertcart.com: LAVEVE Heavy Duty Couch Cushion Support Board for Sagging Sofa, 21.5''x70'' Extra Thick Solid Wood Under Couch Insert with Anti-Slip Dots, Repair Sagging Spring Sofa and Replace Worn Cushions : Home & Kitchen

Review: Glad I found these - We have a love seat and couch in our sunroom which are of good quality. However, the straps got stretched out from young children jumping on them, and the seats sagged so that they were no longer comfortable to sit in. I saw these and decided to try them. To my delight (and surprise) they not only work well, but were very easy to install.
Review: Instant difference — made my couch feel brand new again! - I noticed an immediate difference as soon as I placed these couch cushion support boards under my cushions. My couch feels so much more supported and I’m no longer sinking down into it like before. It also doesn’t feel like it sits so low to the ground anymore, which completely changed the way the couch feels overall. My couch isn’t even three years old yet, and it was really frustrating how much it had already started to sag, especially since it wasn’t cheap. I honestly wish I had bought this sooner. The only small thing is that it does raise the cushions slightly, so you can kind of see the support underneath a little bit depending on how you sit it—but honestly it’s very minor and not noticeable enough to bother me at all. Overall, this was one of the best purchases I’ve made for my home. It completely improved the comfort and structure of my sectional. I’m really happy with it and would definitely recommend it to anyone dealing with a sagging or low-feeling couch.

## 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.

### ⭐⭐⭐⭐ 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.
