Well first off this is very sturdy. I think it's going to last a long time. It's well made and the material is very durable plus the boards in it are very thick. It fit perfectly and there is a little play in length because of the space between the boards so I was able to make it fit into end. And honestly this made my sofa feel like it was new again. So firm and no more curving my end of my back because of the Broken Springs. I am very happy with this and would highly recommend to anybody. And it was very easy to use and install.

I’ve never written a review so fast in my life. Bought these chairs a couple of years ago - love the way they look but I could tell they would get too cushy after a while. They had actually gotten so saggy that I had to rock a couple of times to get the momentum to push up and out of them.Couple of nights ago as I’m scrolling on Amazon, these supports randomly showed up. Ordered them immediately without even measuring the chair! They arrived today and I opened the package, laid them in place (where they fit perfectly) and I am currently sitting here without back pain! Less than 10 minutes after I got home, I feel like I have new chairs. I love these so much. Great workmanship and they will certainly last forever. Best money spent.

I never really write Amazon reviews, but honestly felt that I had to share how great this purchase was.I think too many sofas are too soft in general, and you end up sitting very low, which hurts my back. As I bought a refurbished sofa, it turned out it was slumping quite a bit. But this product made it feel like new with a firm seating. The cushions still make it feel comfortable, just feels like someone replaced all the springs at the bottom of my sofa.Got it for my west elm three seater, works like a charm!

My couch has been sagging really bad taking a toll on my back. I’d been putting off buying one of these support systems. I wish I’d done it sooner! The immediate noticeable improvement! Now instead on fighting for my life to sit upright on my couch, it actually holds everything up. It adds some firmness as well. It’s well made, not cheap at all. The size is good, my couch is a little over 6ft long so I bought the largest option and it fits nicely. Also easy to use I just opened the package and unfolded it so there was no assembly.

I used this product under the cushions on my queen sofa sleeper. The left cushion no longer sags and is now comfortable to sit on again.Easy to install. I've only had it in use for one week so I can't speak to longevity but so far so good.

This has to be one of the best invention for preventing sagging couch cushions especially when the springs to your sofa starts to hurt and making sitting on the couch and possible. I was thinking about going to home Depot and having them to cut some plywood to place under the cushions on my sofa seeing that the cushions that I purchased did not do the trick at all. Then to my surprise I stumbled across these plywood couch inserts and I must admit they work perfectly! If you're looking for firmness or product that will prevent you from feeling the springs in your sofa or without having to purchase a new couch this would be a perfect investment. They're heavy duty and makes the sofa feel very firm and like new again. I'm a happy customer!

Huge difference when I easily install it on my couch. We’re not sinking in the couch when we sit and can easily get up off the couch. Very sturdy and a lot of support. It gave our couch and loveseat an extended life and prevented us from buying a new set. Highly recommended.
Wonderful product

We have a sectional and my husband always sits in the same spot near the seam. We got the longest size and started it halfway under each corner seat to connect the 2 middle seats.One piece where he sits was already breaking down. Because we extended it to the 2 sectional pieces I am hoping this will give our couch an extended life.It looks a little better immediately, and is comfy to sit on, you don't notice it is there. Much more affordable then a new couch and it took longer to vacuum then it did to install, it was that easy. I just wish they made longer one for 96" couch lengths.
