LIFE CHANGING FOR SAGGY COUCHES! No more back pain!
Wow! Where has this been my couch life?!? I have only had my couch a few months, but it would make my back hurt b/c it was saggy already. (It was cheap, what can I say.) I was curious how this would actually work. I didn’t think it would make that big of a difference. It is a night & day difference!!! So firm now! So comfortable to sit on my couch now. It is like magic how it much it has changed the comfort of my couch. Buy it! Life changing! My back doesn’t hurt anymore! It seems to hold in place fine after a few days. I’m in love!

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.

Great fast fix
recently bought a couch that was a floor model and realized the cushions felt different than buying a newly couch. Bought these with hope that it would help the feel of the cushions. It works tremendously I couldn’t be happier. It really helped my situation and for the price point, it was a lot better than having to redo the cushions or having to purchase a new couch.

Works great
Helped a lot with sagging, it change the comfort a little, you feel a little harder the seat, but still works great. I would like more if there's some type of cushing on it 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.

Great fix to add more support
Purchased this before a renovation and just now have gotten around to using it on our 20 year old couch. It fits perfectly, adds good structure and support, and helps to eliminate one spot that possibly has a broken spring. The couch is still as comfortable as it always has been, but definitely provides better support. Extended the life of our couch, saved us money from investing in new living room furniture. And for less than 50 bucks!

Worth the money!
Honestly, I wasn’t sure how these would work. However, I was pleasantly surprised to find out that not only do they work, but they provide a surprising amount of support. I measured and used these on one section of an L-shaped couch. But it works so well, I ordered a second one for the other side. I highly recommend this to anybody who is looking for added support in a couch that is beginning to sag.

Supportive and Sturdy
It is pretty good at supporting! It is smaller than expected but still nice. Sturdy enough as well, and it doesn't move around under the cushion. It is thick but thin enough that it doesn't affect cushion height. Just four stars for the price for the size.

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.

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.

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!
