    • This actually works!
Size: 28x72'' | Super Wide Sofa
It's actually kind of insane how well this product works. The stability it provides to my sagging couch means it no longer becomes a bottomless pit. It fit perfectly along the base of my couch (measure beforehand!), and was easy to install on my couch. It makes my cushions stay in place but also provides much needed support. ... show more

    • A good solution for a sofa that does not feel firm enough
Size: 24x48'' | Wide Loveseat
I am an average sized woman but I sit on the same area of my sofa...and my new sofa just was not as firm as I wanted. I think this is an inexpensive solution to give it a firmer feel.

    • Best quality and built to last. Get them for everything !!
Size: 24x72'' | Wide Sofa
These are the best! I’ve tried other brands before, and they were just “eh.” They would give out quickly, and the boards would bend and get flimsy over time. These are strong, solid, and built to last. I bought a new couch and put these in each sectional piece and the chaise from day one to help keep it like new. I also used them on another couch that you would sink into because it wasn’t firm enough. They completely restored the support and have worked incredibly well. The quality and construction are top-notch — very high-quality materials and strong stitching. 10 out of 10. I’ll be using these for all my furniture needs going forward. ... show more

    • Worked like a charm
Size: 24x72'' | Wide Sofa
Bought this for my boyfriend's sagging couch. Had purchased cushions that were supposed to slide under each section, but they were too small for each section and was uncomfortable. This was the exact right size and fit perfectly. Now the couch is much more comfortable and is a lot cheaper than buying a new couch! ... show more

This product just saved me so much $$ and my 20 year old couch from the dump! Very sturdy and exactly like the product description. We no longer sink down into the cushions. So much easier to get up!
