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

I wasn't sure if this would live up the advertised claims but it absolutely did!Installing is super easy as removing cushions, unpacking and placing grip dots face down then replace cushions back on top!It's made very well and the weight of the wood surprised me. I postioned mine end to end on my three cushion couch more towards the back cushions. I spread out so the slats were resting on the side arm frames to ensure it was supported on the couch's frame.The cushions have very little sag in them on my couch but the under support was starting to make it harder to get out of the couch, I'm not ready to purchased a new couch. These saved the day.Night and day difference it stiffened the support back to new condition!It has extended the time before we will need to replace the sofa I'm so pleasantly surprised this product worked so well!

I did not think my couch could feel like new again but these did the trick. I especially like the foldable ability, I've doubled up on two areas where the sagging is the worst and now my couch feels even all over which I didn't think was possible. It's made really well and although it doesn't say, I'm pretty sure it's made of canvas (a solid material). I ordered two 54' love seat sizes which was really abt 51" and weighed 17 lbs each. They're not as long as advertised, each slot measured 3.5" x 20" x 1/2 inch thick (not 5" x 21.5") but they still fit and did the job excellently. Just open the package and lay them down, done. Saves money by not having to buy a new couch!

It’s has good thickness and size. The dimensions were exactly as advertised and the durability has been amazing because I’m a big heavy man and this support was a couch saver! The color is nice too.

Wow! Now, your couch doesn’t magically turn brand new, but I love my sectional and didn’t want to get a new one quite yet! And I love it even more now that my friends and family aren’t swallowed up by it! It made for some hilarious moments, but, now we can make COMFORTABLE and hilarious memories together! I purchased two of them for each couch portion of my L shaped sectional. I bought the gorilla grip No slip couch gripper to go over the for my Gorilla Grip heavy duty cushion supports, to ensure they wouldn’t slide anymore or have to constantly readjust them. Boom! No more sagging way down and cushions sliding all over! Is it a 100% positive difference? Yes!! Does it feel like a brand new couch? Almost!! This is only Day 1, so I will update if my opinion changes at all! So far, so great!!

When I ordered this in the back of my mind, I thought I was gonna be returning it because I could not believe that this would work. Shockingly it’s like sitting on a new sofa. I still don’t understand how it works because it feels like the cushions are flat so I couldn’t understand how this would work, but it works not gonna question it anymore just gonna order another one for a different sofa. I am amazed.

Oh my goodness. My couch was in excellent condition except seat cushions. I thought I would have to purchase a new sofa so I tried this solution first. Much to my skepticism my hopes weren't too great. But it works. Its like a new sofa. My cushions are firm again. Yes. I would definitely recommend buying.

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, or an uber-luxurious 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...or just cheap. Either way, I did a little research and stumbled on this support system. The reviews seemed mostly positive, so I copped it 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.

Why did you pick this product vs others?:I have a couch that’s about a year old; however, one cushion in particular was sagging into the couch. I thought the problem was not just with the cushion but more underneath. I bought this hoping it would do the trick and it did! It gives that area support now and no more sitting and sinking into the couch.
