They work great. Save yourself some money from buying a whole new couch
I am not being dramatic when I say I was ready to buy a new couch. These inserts are great. I have a VERY old couch so I used 2 in the center cushion and one on the other side that is most often used and sitting on it now I really feel like I could have went without buying a new couch. Oh well. I will keep the inserts and use them for extra support under the new couch anyway

They make the furniture feel new again.
These made a great improvement for my back and bum under my love seat cushions. I have been very uncomfortable and finally realized that my love seat recliners needed extra support underneath. I read several reviews and these were a great choice. Once I received them, I opened each cushion package and they revived immediately. I have each one under a cushion. It’s like my loveseat was revived . There is a slight height gap difference, but it’s hardly noticeable. My back and bum are happy again.

Very weak foam, absolutely not high density!
Don't bother with this product. Absolutely not high density foam. Has to be the weakest foam made. 2 inches compresses to about an eighth of an inch with anything over 10 lbs. Zero extra support for anyone sitting on a sofa, except for maybe a chihuahua or a Yorkie.

Help for an older couch
My couch is about 10 years old and some of the cushions started to sag. These helped immensely. It’s only been a few months so I’m not sure how long they last, but the price is affordable enough that I would buy them again if needed.

Good quality
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.

My couch has been sagging for months and I kept putting off doing anything about it because I figured fixing it would involve some complicated process or spending a ton of money on new cushions. I saw these foam inserts and thought they looked too simple to work but I ordered them anyway because they were cheap enough that it wasn't a big risk. They arrived a few days ago and I threw them under the worst cushions expecting maybe a tiny improvement, but they've made the couch feel way more supportive than I expected, like it's not perfect but it's so much better that I'm not constantly sinking down into that saggy spot anymore. The foam is thicker and more solid than regular cushion foam but it's not rigid like a board would be, which is good because I didn't want the couch to feel weird or uncomfortable. Installation is literally just lifting the cushion and putting the support underneath, takes about ten seconds and doesn't require any tools or special skills. They've stayed in position since I put them in, haven't slid around or moved out of place even with daily use. One thing I appreciate is that they're flexible enough that I could probably cut them down if needed for different sized cushions, although I haven't had to do that yet since they fit my couch fine as is. The grey colour means they blend in pretty well if you happen to see them between cushions. Definitely giving these 5 stars, they solved my sagging problem without being a hassle or costing a fortune.

Esperaba much mas del producto. Funciona decentemente

My old sectional couch was starting to feel like sitting in a valley with a deep sag in the middle so I decided to give these a try since they're specifically contoured and made of firm foam. The size was perfect for my individual seat cushions.Installation is simple, lift the cushion, slide one of these curved foam pieces underneath centered where the sag is worst, and put the cushion back. No measuring, no cutting. The curved shape actually matches the way cushions dip, and the foam gives surprisingly good lift without turning the seat hard. It adds support but still has a tiny bit of give which made it not feeling like I'm sitting on a board. After a couple weeks of use the sag is basically gone. The middle no longer bottoms out. No slipping or shifting, the foam grips the cushion bottom and the sofa deck pretty well. I'm very satisfied with this.

I bought this couch cushion support to deal with a sagging seat that had been getting worse over time, and I was honestly surprised by how much of a difference it made. When it first came out of the packaging it looked very flat, but after letting it expand fully, the foam became thick and supportive. Sliding it under the existing cushion took only a few seconds and didn’t require any tools or adjustments, which made the whole process incredibly easy. Once in place, the couch immediately felt firmer and more supportive without becoming hard or uncomfortable. The high-density foam adds just the right amount of lift, so you no longer sink into the sagging spot, but it still feels comfortable for long periods of sitting. I also like the slightly curved shape, which seems to help distribute weight more evenly and keeps the support from shifting around during daily use. It doesn’t completely turn an old couch into a brand-new one, but it dramatically improves comfort and extends the life of the furniture. For the price and how simple it is to use, this cushion support is a great solution if you’re not ready to replace your sofa but want to make it comfortable again.
