  • Worked well for our older sofa
Size: 70" Sofa Color: Gray
We have an older sofa (10 years) that we love but the middle was sagging. The cushion support board helped tremendously. We are also going to put an extra foam insert in the middle cushion that is also sagging. Altogether, much cheaper than getting a new couch and it is noticeable more comfortable. Very easy to install. ... show more

  • Awesome
Size: 70" Sofa Color: Gray
Love the product quality, design and it's reasonably affordable. Gorilla Brand has certainly diversified, most of their products are exceptional if not comparable to other quality brands. At any rate, I am satisfied with the actual product, fit the sofa perfectly, moreover, provided the. needed support for cushions. Just for anyone considering the product, it definitely helped our leather sofa cushions, gives them stability. Will update after a fair amount of time has passed to give pros/cons. ... show more

  • I love them!
Size: 70" Sofa Color: Gray
This has to be one of the best invention for preventing sagging couch cushions especially when the springs to your sofa starts to hurt and making sitting on the couch and possible. I was thinking about going to home Depot and having them to cut some plywood to place under the cushions on my sofa seeing that the cushions that I purchased did not do the trick at all. Then to my surprise I stumbled across these plywood couch inserts and I must admit they work perfectly! If you're looking for firmness or product that will prevent you from feeling the springs in your sofa or without having to purchase a new couch this would be a perfect investment. They're heavy duty and makes the sofa feel very firm and like new again. I'm a happy customer! ... show more

  • Works well, which more sizes for sectionals
Size: 70" Sofa Color: Gray
We have a sectional and my husband always sits in the same spot near the seam. We got the longest size and started it halfway under each corner seat to connect the 2 middle seats. One piece where he sits was already breaking down. Because we extended it to the 2 sectional pieces I am hoping this will give our couch an extended life. It looks a little better immediately, and is comfy to sit on, you don't notice it is there. Much more affordable then a new couch and it took longer to vacuum then it did to install, it was that easy. I just wish they made longer one for 96" couch lengths. ... show more

  • These are GREAT!!
I’ve never written a review so fast in my life. Bought these chairs a couple of years ago - love the way they look but I could tell they would get too cushy after a while. They had actually gotten so saggy that I had to rock a couple of times to get the momentum to push up and out of them. Couple of nights ago as I’m scrolling on Amazon, these supports randomly showed up. Ordered them immediately without even measuring the chair! They arrived today and I opened the package, laid them in place (where they fit perfectly) and I am currently sitting here without back pain! Less than 10 minutes after I got home, I feel like I have new chairs. I love these so much. Great workmanship and they will certainly last forever. Best money spent. ... show more

  • Did not work for us.
Size: 70" Sofa Color: Gray
The product itself seems very sturdy and priced fairly; however, when the support boards were placed under our sofa cushions it shifted the center of gravity forward so that anyone sitting/lying on the sofa is unable to maintain a comfortable position. (You feel like you are falling/sliding off of the sofa.) We hoped the cushions would conform to the new shape underneath them but ultimately decided we had to send this item back before the Amazon return window closed. Very unfortunate as we hoped this would make the sofa more usable. :-( ... show more
