GORILLA GRIP Heavy Duty Couch Cushion Support Board to Fix Sagging Sofas, 21.5 x 70 Sofa, Thick Plywood Boards Add Strong Seat Supports, Stays in Place, Replacement Stuffing Under Couches, Gray

This cushion support did wonders. Our sofa is great sofa and did not want to purchase a new one. The cushion support is very durable, fits perfectly, and easy to install. It’s not bulky like some cushion supports where you can see it when you walk into a room. The family are happy because they’re not sinking into the sofa. Overall, I would definitely recommend this product.

There is a big difference before and after. I have had my couch for two years, I could start telling the wear and tear, along with the struggle getting up from the couch. I only purchased for the couch to try it out. It definitely does what is supposed to. I am going to order for the love seat.

I have tried several products but this seems to be a decent option. It's a notable difference in the support from this product. If your sofa base is in decent shape, then I think this will do the job. I have back issues and cannot sit on any sofa for a long period of time however, this does provide additional support. It makes getting up from the sofa easier. Not sure about it shifting beneath the cushions but time will tell. I will order one for my other sofa now that I have tried it.

Works great for my outdoor furniture. The cushions would sag when sitting for a while but these supports do a great job. No more readjusting cushions. I bought the loveseat size and two chair sized for my set.

Love this product, made my 1500. Leather couch sit like new, it’s at least 15 yrs old in great condition. Was kind of hard to get out of , now it perfect

I am really impressed this works great on a sofa that I loved but was going to have to get rid of. The quality is good and the fabric frame allows for some flexibility but holds firm. I highly recommend.

This seems to be another one of those “your mileage may vary” products. For some, it’s a lifesaver. For a few others, it has some impact but is mostly mediocre/average. For the rest, it’s wack. I’m somewhere in between the last two.Listen, I get it—comfort’s a spectrum, and like pain or your body's reaction to gluten, it’s quite subjective. I can’t speak definitively, but I feel like your reaction to this product will depend on the original quality of your couch. I’m not talking price or aesthetics—I’m referring to quality of materials and craftsmanship. Think Amish furniture. Or maybe I’m totally wrong and none of that matters. It’s up to you, really.So, onto my situation. I have a couch that’s slightly above IKEA quality, meaning some thought—however minimal—was put into long-term comfort. It’s been more than a few years, and the base on one side that supports the seat cushions has low-key turned into the sunken place. You know the feeling—like you’re about to be transported somewhere you don’t want to go. In my case, it’s a horrible trip to back pain alley.I could’ve gone to a second hand store, online marketplace, Crate & Barrel, or an uber-luxurious mom-and-pop shop, but I wanted to work with my current couch. We have a history, and I want to keep it in my life for as long as feasibly possible. Guess I’m kind of a romantic. I did a little research and stumbled on this support system. The reviews seemed mostly positive, so I copped it in an instant.First reaction: it definitely has an impact. The sunken side of the couch was noticeably firmer with this laid on top of it. Mind-blowingly so? Nope. Enough to feel like a new couch? Not to me. I’d say the firmness and comfort increased moderately—enough to notice, but not enough that I’d call it a new couch. Again, this could be based on the miserable condition of my current couch—or not. There’s no way to know for sure. But I’d give this a C+ or B- for improved comfort.

I bought this for an old couch to give more stiffness and support to the sitting area under the cushions. Works like a charm! Much cheaper than buying a new couch.
