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've had THE WORST back pain and thought it was due to my old couch. Imagine my surprise when I bought a brand new couch and the problem didn't go away. Admittedly, the new couch was <$1000. I was about to return it and get ready to get an expensive one with springs in the cushions and all that. Welp, I found these bad boys, and the problem is solved!

My older sofa cushions were sagging and making my back ache. As soon as I placed this Gorilla support under my cushions, my sofa was much more comfortable. I'll be buying another one for the other half of my sectional. Very pleased.

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.

So happy that we purchased this sofa support. Works great and fits great. The minute we sat in it we could feel the difference. Highly recommend. This is a great alternative to buying a new sofa.

It really works to make the seat of your couch firmer without feeling like a hard board. It's a series of hard slats, covered and held together by strong silky cloth. You put the original cushions on top of It and they look normal. It's still comfortable but firm. It makes the seat maybe an inch higher than it was before, which makes it easier to get up from the couch.

I was very skeptical about this really keeping the cushions from getting smushed every time someone sat down on the couches. Since installed (come ready to put in place), I have not had to remove one cushion to fluff up. They definitely work like it says. My couch cushions look so much better!

I need a new couch has no support anymore. But I am waiting. So I thought i would try and it really works. Almost brand new again. So my old couch will last me a few more years.

This product is amazing. My sofa looks great. I have a sofa bed that doesn't offer much support under the cushion. This was easy to to install. I used it along with a memory foam cushion under. I can't believe the difference. This would work just fine on a sofa that doesn't have a bed in there. Mine needed some extra help as the cushions would sink in a bit because of the extra space on a sofa bed. It's nice to receive quality product.
