Highly recommend for a nice amount of support under soft old cushions.
Worked perfect. Our older sofa cushions were pretty squishy and these boards added just the right amount of support. Cushions have just the right amount of firmness now - still comfy for lounging but older folks can get up and down on them easier now.

A must have for sagging seat cushions!
Honestly, I was extremely skeptical on buying this product, but I am so glad I did. I bought a new couch and oversized chair for my living room a few months ago. I didn't like that the bottom cushions were already starting to sag. I took a chance and purchased this couch support. One of the best purchases I've made. This has made such a huge difference in overall support. If you don't have one, you should try it. My back doesn't hurt anymore when I sit for a while watching movies. It is exactly as described. Make sure you remove your bottom cushions to measure the seating space between the ends of the couch. Mine had a little more room, but I purchased a size down and it fit perfectly. I also accounted for the front edge of the couch, ensuring the appropriate depth so the support didn't protrude over the edge. The product was packaged well, was in perfect condition and works better than described. Open it; unfold it, and if you measured correctly, it will fit perfectly.

Thank you Gorilla Grip
I wish I had known about these support boards sooner! This does the job for me. It is firm and keeps my couch cushions in place and my back supported. I’m very pleased and recommend you give this a try!

Just what I wanted
It definitely accomplished its purpose of making my sofa cushions more firm! New cushions only made the sofa sit higher and still sag, but this support firmed up the entire surface. I've heard you could do the same thing with a sheet of plywood, but this has a better appearance with the covering, so no splinters. My back appreciates this support, too!

It works!!!
My mom purchased this. Her couch and love seat are a couple years old and her couch has gotten a little slouchy. (She's a couch sleeper) This fit the couch perfectly and made it so nice and firm. It feels like new again. She is going to purchase one for the loveseat too. It's not as slouchy but just to make it last longer.

Works Well, Just Make Sure You Measure First!
I’ve only had this for a few days, but so far I’m impressed! It significantly improved the sag in my sofa as soon as I put it under the cushions. I did hear a popping sound when I shifted my knee on the couch last night, almost like a board may have cracked, so I’m hoping everything is still intact. Other than that, I’m really happy with it. One important tip: measure before you order. The cheapest option is surprisingly narrow and probably won’t work for most normal-sized sofas. Mine ended up being a perfect fit!

Saved me
Someone sat down on my couch a little too hard and broke the support underneath. I honestly thought the couch might be done for, but then I found this. I was worried it would make the couch feel too stiff, that it wouldn’t actually provide enough support, or that I’d be able to feel it underneath the cushions. Boy was I wrong! It made my couch feel almost brand new again. The cushions are supported without feeling stiff or uncomfortable, and I don’t notice the support underneath them at all. This saved me from replacing a perfectly good couch. Highly recommend!

Can finally relax on my couch, wish I got this sooner
I am 37 weeks pregnant and my thrifted couch was wayy too soft for my back. I just recieved this this morning and put it on my couch and I could cry it’s instantly so much more comfortable, I don’t feel like I’m sinking/destabilized/fighting to readjust. I love the look of my couch and did not want to search for a new one with baby on the way- this solved both problems instantly. Great price point and so easy to set up, I highly recommend

Great Product
this product works great, we have a couch that had no cushion support but the material was great so we used this to get support in our couch. Our couch feels like brand new, the cushion support helps it to feel firm and it stays in place under the cushions. I will buy this again for sure if I ever need it for another couch.

Saved our sofa!!!
Amazing product. One of the slats on our sofa snapped. This product was easy to use, very discrete and provided a strong base so it can still be used. Would recommend.

Great support for our couch!
This Gorilla Grip support board works great for our couch. The cushions seem more firm and does not sag into the springs when you sit on it. Would definitely recommend!

It's an exact fit. Don't oversize.
Exact fit as advertised. Stiffens the old frames works for me. Good job, not the cheapest but some don't work. Hope this is helpful.
