  • Our sofa cushion supports are of higher density. They are 2.9 pounds/cubic ft or 46D, 46 Kg/cubic mt, but the ones currently in the market measure only 2.5 pounds/cubic ft or 40D, 40 Kg/cubic mt. The lower density is incapable to cure the sagging.

  • Installation is quite simple. Just place the cushion support under your existing sofa cushion to provide additional firmness to repair the sagging. It only takes a few seconds!

  • Yes, ofcourse! The cushion supports can be cut to fit your sofa dimensions. Its trapezoidal design offers excellent stability and support even when trimmed.

  • Absolutely not! The high-density foam is designed for comfort. Unlike hard boards or inserts, it provides firm support without feeling rigid or uncomfortable.

  • Each support cushion measures 20 × 20 × 2 inches, a size designed to integrate seamlessly under your sofa cushions without being noticeable. It could also be trimmed to fit your sofa.

Worked well. Worked as expected. Size is a little small and no idea for long term wear.

These seat supports offers nice support, however they run small for most sofas. I have a standard sized 3 cushion sofa and it needed 4 of them to cover the length of the sofa perfectly making the value less than I hoped. It will work for a short term solution, offering support for your sofa, but eventually I will have to have the cushions themselves redone with new foam. This product will not serve as a permanent solution for sagging furniture.

As a Vine reviewer, I'm excited to share my experience with the Sofa Couch Cushion Support. This clever foam trapezoid has genuinely brought new life to my worn-out couch.The support is incredibly easy to install - simply place it under the cushion, and voilà! The high-rebound foam provides excellent support, lifting the sagging cushion and restoring the couch's original shape.But what really impressed me is the impact it's had on my posture. With the couch's newfound support, I find myself sitting up straighter, which has reduced my back discomfort. It's amazing how something as simple as a foam trapezoid can have such a profound effect.If you're struggling with a sagging sofa, I highly recommend giving this product a try. It's a cost-effective solution that can breathe new life into your furniture.Pros:- Easy to install- High-rebound foam provides excellent support- Restores couch's original shape- Improves posture and reduces back discomfortCons: None!

Our sectional couch had a noticeable sag, though we do not know the exact cause. When I came across this cushion support, I figured it would be worth a try.It came packaged air tight, and the instructions mentioned to let it sit and puff out to its maximum size for 48 hours. I did let it sit for 48 hours, although I believe it was at its maximum size the minute I unwrapped it. It did not really look any differently two days later.So then we placed it where it needed to be and put it to the test. It definitely provided a noticeable difference in support when sitting on it, and the couch is visibly less saggy. The thickness of the cushion is pretty decent and helps maintain the comfortability of sitting on the couch. I think the value is worth it if it fixes your problem and stands up to the test of time. If you have a sagging couch, I think it's definitely worth a try!

I’d like to start by saying, I did not use this as intended. We have a recliner couch that does not have loose cushions. It does have saggy seats, and we are trying to figure out a way to add support without investing in a new couch. We put this cushion support on top of the couch seat and put the couch protector cover (dog proofing) over it. While the center of this cushion support is perfect, very firm support, the sides are sloped, which leaves a smaller support area. It may work perfectly if it was under a cushion. I just wish the entire piece of foam was the same thickness, to completely support the cushion without the sloped sides. I’m guessing the sloped sides allow the couch cushion to lie flat and not expose the cushion support underneath, which makes sense, but maybe just have one sloped side. Hopefully, I can find a foam cushion support with the same thickness throughout, and as well made as this one, which is why I still gave it 5 stars.

I use these to bolster the cushions on my loveseat, and they work like a charm! You can cut them to fit (I didn't have to do this, as they are the perfect size!). Once placed, you can't see they're there, but you can feel a huge difference! These, in my opinion, are better than the slats that are bolsters (I've had both) and make your couch "cushier". There are 3 included in the order if you have a 3-seat sofa. Great purchase!

I really wish they made a rectangular version of this. Long story short, I bought a cheap new couch and it was killing me to sit on it. I used this to reinforce the cushion. It works, but I wish it were more rectangular-shaped. This would work well if only the middle part of the seat cushion is depressed.
