GORILLA GRIP Heavy Duty Couch Cushion Support Board to Fix Sagging Sofas, 21.5 x 70 Sofa, Slip Resistant Thick Boards Add Strong Seat Supports, Replacement Stuffing Firmer Couches Accessories, Grey

Works perfectly! Added just the right amount of stability to our couch!

Fits my sofa perfectly and renews the firm support. Very affordable fix for a sofa I don’t want to replace but needs a firming up.

When I moved the movers damaged my couch. It’s quite old so was not worth investing in an expensive repair. The damaged areas were drooping substantially. I installed this and the couch feels like new. It’s very comfortable once again and very stable. Every few months you will need to take the cushions off and adjust, but it only takes a few minutes. It was such an easy fix and so much better than buying a new couch.

I bought this to use on our sofa that has a pull out bed because the cushions seemed to start to sag. It has had helped a lot with the sagging. It feel a lot firmer. I only give it 4 stars though since the grippy dots don’t seem to prevent the cushions from sliding out. It also folds up like an accordion if you want to remove it. It’s pretty easy to use.

I never write reviews. If you find yourself scrolling through the reviews, let me stop you. Wether is bad cushions or springs. This product is hands down what they say it is and does exactly what they describe it does! Heavy duty and well built! Worth every cent! I AM VERY PLEASED! My couch feels amazing and my back and body is happy.

These really work..my sofa is like new. Went with Gorilla because all of their product are top of the line and do what they claim.....these are heavy which helps them work best.....

I was not sure how this would work at first. I thought it might be to thick and that you would be able to see it under my couch cushions. It works wonderful, lifting up and supporting the sagging cushions, they are almost as firm as when I bought the couch. Before using it, if you sat on the couch, you sank and it was hard to get up. Now the couch is easy to get off of again. It is black/grey in color, and my couch is grey, which is why i ordered it. I have a sectional and it goes all the way down the long section and can not be seen at all. If this had not worked, I was going to replace the couch, so this is a much cheaper option than that. I think with this product I can get a few more years out of my old couch

This is really good to have! I spent a little money on a new couch and when I thought the cushions were sagging, I put this under them. It made the couch a little too firm so having this going forward is a good move. Great value for the money, better than the foam squares and far easier to use. The size is perfect, so measure your couch so you have the right size. It’s definitely thick but it’s also very light and easy to remove and store. I’m very happy with this gorilla grip support. The perfect solution for for cushions that sag for sure.

Thick, quality material, easy to install, solves sagging, sofa cushion seat feels restored when sitting.

Well made and professional, it fulfills its purpose perfectly. I definitely recommend it.

Work good with our letter cushions we felt that we were sinking into sofa all the time we installed it and felt the difference right away

Really pleased with this item. Just what was needed to make our old sofa more supportive.

Good firm support
