GORILLA GRIP Heavy Duty Couch Cushion Support Board to Fix Sagging Sofas, 23 x 19 Armchair, Thick Plywood Boards Add Strong Seat Supports, Stays in Place, Replacement Stuffing Under Couches, Gray

Well first off this is very sturdy. I think it's going to last a long time. It's well made and the material is very durable plus the boards in it are very thick. It fit perfectly and there is a little play in length because of the space between the boards so I was able to make it fit into end. And honestly this made my sofa feel like it was new again. So firm and no more curving my end of my back because of the Broken Springs. I am very happy with this and would highly recommend to anybody. And it was very easy to use and install.

Very sturdy. Quite hefty so you know it will provide needed support. It was very easy to put on the couch—just unfold the accordion sections and replace the cushions. I feel that the support is like sitting on a new couch now.It does make sleeping on a well-loved couch a bit awkward at first because you feel like you’re angled forward a bit, but I got used to it, lol.

Huge difference when I easily install it on my couch. We’re not sinking in the couch when we sit and can easily get up off the couch. Very sturdy and a lot of support. It gave our couch and loveseat an extended life and prevented us from buying a new set. Highly recommended.

These work great. they have made such a difference with my sagging couch. It feels almost like new. Thickness is great and it will last a long time. I love it.

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.

I never really write Amazon reviews, but honestly felt that I had to share how great this purchase was.I think too many sofas are too soft in general, and you end up sitting very low, which hurts my back. As I bought a refurbished sofa, it turned out it was slumping quite a bit. But this product made it feel like new with a firm seating. The cushions still make it feel comfortable, just feels like someone replaced all the springs at the bottom of my sofa.Got it for my west elm three seater, works like a charm!

Was about to buy a new sectional because one side sagged. Otherwise couch looked great. Bought this product and it worked wonders. Just rolled it out and put my cushions on top. You can not see. It or notice any difference until you sit on it and you no longer sink! Just saved myself the cost of a new sofa.

No idea how, but one side of my sectional broke. Maybe the wooden slats underneath the cushion? Can't see it. It started to sink way down, though. Anyway, I've had it since 2018, but due to a messy dog and messy boyfriend, I'm not quite ready to invest in a new couch. I measured this to the broken side of the seat of my sectional, and WOW! It's actually firmer than it was before and feels brand new. Now I can keep this couch while I train my dog and boyfriend!
