## 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.
