Worked perfectly
This was the perfect amount of support for my sectional. I ordered one for my side, amd then a second one for the other side because it made the couch sit like it did new. Flexible support well worh the money. Also the cushions stay put now.

Sturdy & Worth Every PENNY
This product does exactly what it says is going to do and it is very sturdy. It’s very easy to use. In fact I’m gonna order some more for my loveseat and sofas. Excellent product as long as you don’t mind paying for quality and this is a great product. If you wanna spend a little less or a little more and go another route, you could do that too, but it won’t be as sturdy or as affordable as this product.

They work!!!
Amazing perfect for my couch!!! No sagging, no stuffing pillows underneath the cushions. My couch is 11yrs old. Been through all my kids and my days of couch potato. Now my couch is restored, looks nice and finally is comfortable again!!! I give the “gorilla slats”are a must for older couches!!!!

More comfortable sofa because of the Gorilla Grip
This support board is good. It provides strong support. I have given it four stars because it is not as firm as I would like. I had expected it to be more rigid than it is given that it's listed as "heavy duty." However, my couch might be softer than I realized. That said, the boards within the device seem to be well-made and assembled within a fabric framework. My couch is more comfortable now that I have the Gorilla Grip.

They work!
Our sectional was really sagging from age. These really do the trick! The cushions are still soft but these give that support where you don’t feel like you’re sinking. A well worth it purchase until we buy new furniture.

Works like a charm.
Fits perfectly and made my couch instantly comfortable. Only had it a week, so can't comment on long term durability.

The cushions stay in place with the grips. No complaints so far. I got the item today.
I ordered this item for a sofa i had for 7 years. I bought this because the sofa was in great shape but the cushions were sinking. I was absolutely shocked to see the results. The cushions felt like new. It felt firm when my husband sit in his favorite retirement spot . It could be 4 inches longer in length but it worked out. It feels durable, the thickness is good and easy to open. You don’t see it under the cushions.
