Couch Cushion Support for Sagging Seat, 20"x20"x2" 40D High Density Curved Foam Sofa Cushion Support, Under-Cushion Sag Repair,Grey Set of 3

These work much better than I expected. It’s helpful to give more support.

Very good product, very comfortable on my couch

I like that I don't sink into my couch anymore. The only problem is they do move around some. Also, you can see them under the cushion. Here is a picture after sitting on the couch. So my living room looks messy. Maybe I should have purchased the bigger size.

The foam is thick enough to boost your couch cushion. However, it’s curved on one side and makes your cushion uneven. I had to flip it and move it around to finally make it work on my couch.

I couldn’t be more shocked at what arrived. It was a little small compact package. I was sure it was the wrong thing until I cut into the packaging and it sprang to life. It has given new life to the sunken in place on my sofa where I sit all the time. I am thrilled with the firmness, material and value for the money.

These are fantastic. My cushions feel like they are brand new. I give them a 10 out of 10. If you are looking to get a little more time out of your couch and loveseat, I definitely buy these.

Just right for what I needed. One seat cushion on our sectional is so popular that it the foam insert had lost its memory compared to the the others. This insert added just enough to lift that one back into alignment with its neighbors, and provide the firm support that we prefer for the seat cushions. This exceeded my expectations.

easy to install, good height, seems sturdy so far with good support. The only down fall is that they are actually a little small for the size of each of my couch cushions, but not enough to return and search for another one.

Adds great support economical way of extending the longevity of my sofa

Esperaba much mas del producto. Funciona decentemente

Would say this is a sold 3.5 star. The product or product design is a bit flawed. The problem I have is when I use this cushion on my couch. It does raise the cushions to their original height, but the problem is there is a big gap between the cushion and couch. And because it has a peak in the middle the cushion also tilts back and forth when you sit on it.

We have an older couch with a noticeable indent in the cushion we used most often. We love the couch and aren’t ready to replace it yet, but it was becoming uncomfortable to sit on. To address this, we purchased the couch cushion support to add some loft to the cushion.The cushion support arrived vacuum-packed in a small package and needed time to expand. It mostly expanded within a couple of hours, and by the next day, it was back to its full size. There was a strong petroleum rubber scent when we first opened the package, so we left it outside on our back deck for about a week to let it dissipate.The cushion support was smaller than I expected when we put it under the couch cushion. Based on the ad pictures, I thought it would be about the size of the cushion, but it was significantly smaller. Despite this, it worked well to prop up and fill in the centre of the cushion. However, if you’re looking to fill the entire area under your couch cushion, note that the support is only 20 x 20 inches square. The cushion support is also thicker in the middle and thinner on the edges, which helps it blend in with the existing cushion.Overall, we are happy with the effect once it aired out. It provided extra loft to the area where our couch cushion had flattened over time, extending the life of our couch before we need to replace it.

It's disappointing buying a very expensive couch and chair set and then within a couple of years having your cushions sag. Previously, I've had an upholstery repair company come out under warranty and do some repairs with new straps and foam, but it didn't last long. Now my warranty is gone, and my couch is sagging again.For those of you that have removable cushions, this couldn't be any easier. And for the price, you can't go wrong. One of these may just be sufficient, but heck, if your seat is sagging horribly, buy two of them.I personally don't have removable seats, so I had to flip my couch upside down, take out a few staples where the fabric covers the bottom, and just push this underneath the straps. It solved my problem for now. The foam does seem to be of pretty good quality and it feels like it's high density. Foam doesn't last forever, but I'm hoping I get a little while before I have to do this again.I like how they have made it thicker in the middle. I think that was a very good idea. The foam cushion came in a tiny vacuum-sealed package. It was surprising how much it expanded and filled out within 24 hours.This is an inexpensive, quick, and easy fix for many of us who don't want to buy new furniture because our seat isn't as soft and cushiony as it used to be.It's difficult for me to decide on a rating because some people may prefer a firmer foam, and some may not. Also, some people's seats may be sagging more than others. I also can't vouch for its longevity. I think the price may have gone up recently, too, but so far I'm satisfied.
