GORILLA GRIP Heavy Duty Couch Cushion Support Board to Fix Sagging Sofas, 21.5 x 70 Sofa, Thick Plywood Boards Add Strong Seat Supports, Stays in Place, Replacement Stuffing Under Couches, Grey

I should have purchased this years ago! So we bought a great couch about 13 years ago. We've been so lucky that it has held up amazingly; however, those pesky cushions have been killing our backs, as it's time for a replacement. The problem, we have a 8 y/o son who thinks the couch is his jungle gym. So, no new couch for us until he understands that a couch is for his bottom. I digress... this works wonderfully. Our couch is gray, and you can't tell that the Gorilla Grip in gray is even there. My mom asked if we bought new cushions. It vacuums off easily and will hopefully give us another two years on our couch. We want to buy a new one for the new house. The fit is perfect, and I didn't realize that our couch is as big as it is. Super easy to place under your cushions and no more aching backs and saggy sofa. Would most definitely purchase again.

added support to the old couch which had lost its support/lift. will get us more time and comfort until we can find the perfect replacement set. worked better than foam pads we also tried.

THIS THING WORKS EXACTLY AS DESCRIBED!!!! This couch we have had for about 6 years used on facebook marketplace. It was in fine condition but the seat cushions have definitely gotten softer and not as firm. This works perfectly! When I sat down it felt like a new couch after having this under the cushions. The slip resistant is great too! Highly recommend! You won’t regret it and totally worth the money! The measurements are correct and perfect! This one reaches from one arm rest to the other!

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.

Our couch is pretty new but one thing I didn't care for is that it was softer than I like. I have used Gorilla products, and I found they made this couch seating support and decided to try this to quick fix the issue. Sure enough, it added the much-needed firmness I was looking for and it was not that expensive. Easy to install and fit the entire length of my couch.

This Thing really works !!! My 80yro Mom has problems getting up off the sofa because it started sinking but this made it like new ! Very sturdy and stability is grest ! Problem solved. I just ordered a second one for the matching sofa! Buy it!

Works really well. Used it on a chair that’s 20years old, and of course the only thing that’s wrong with it is the springs got soft. I would say worth the money. Definitely makes the chair stiff.

WOW! I was fighting with my furniture company last year a few weeks, then months after purchasing my foam filled sofa, because one of the areas I sit in the most was curving in and becoming very uncomfortable... this happened to my previous sofa as well. They finally replaced the cushion for me, but within days/weeks it happened again. I finally put a pillow under it, which didn't fit well and looked terrible - and then I found this INCREDIBLE PRODUCT!!! I bought the Arm Chair size because it's only one spot of my sectional that was causing me an issue and from the second I put it under the cushion PROBLEM SOLVED. It actually feels, and looks, brand new again! It's not too thick (as the pillow was) at all, it doesn't show, the cushion isn't lifted at all, but it does cause a fantastic stability and evenness to the cushion now. I fought and fought and fought with the furniture company over this and there was nothing they could do. This is the BEST product on the market for anyone who's dealing with foam stuffed furniture cushions. I don't think it even felt this even or comfortable the day it was delivered. This is like a miraculous feat of magic to sofa (or chair) cushions! I hope they never stop selling it - as the rest of the cushions eventual start sagging in or making you feel like you're tilting to one side, I'll be buying more and various sizes. The color really doesn't matter, as you can't see it once placed under your cushion, so I wouldn't worry about that at all. Fantastic, furniture changing item! I HIGHLY RECOMMEND IT!!

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

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

This saved our couch! We might get another one for the other side because it's been working so well. A very sturdy and high quality product.

Good firm support

I was not sure if this would give support for my sagging pull out sofa, as the cushions were still good, however the base was sagging, so when you sat down you would tilt over. But to my delight, this cushion support board worked, and now no more sagging. The quality is great, and it is strong as advertised.
