LAMINET Deluxe Extra Thick Sagging Furniture Cushion Support Insert| Seat Saver| New and Improved| Extend The Life of Your Sofa| 60% Thicker - Sofa - 17" L x 66" W

Quality is outstanding for a cushion support: Made of a dense, high-resilience foam blend, it feels premium and long-lasting—no cheap, flimsy material that flattens after a week. I’ve used it daily on my 5-year-old sagging sofa for 3 months, and it still retains its shape perfectly (no indentations from regular sitting). The surface is smooth, breathable, and doesn’t stick to fabric cushions—even in warm weather, it doesn’t trap heat or cause discomfort. Unlike thin support pads that tear easily, this one has reinforced edges that resist fraying, ensuring it holds up to years of use. Support is transformative for sagging seats: The 60% thicker design (compared to basic inserts) lifts sagging cushions instantly, turning a lumpy, uncomfortable sofa into one that feels firm but not stiff. It distributes weight evenly—no more sinking into “dips” or feeling like you’re sliding off the cushion. I have back pain, and this support has made sitting on my sofa for long periods (watching TV, working) pain-free— it provides just the right amount of firmness to support my lower back without being harsh. Even for large sofas, the 66" width covers the entire seat base, so every seating spot gets consistent support. Build quality is durable and well-crafted: The foam core is dense and uniform (no air pockets or uneven thickness) and wrapped in a strong, tear-resistant cover that’s stitched neatly. The edges are rounded and reinforced, so they don’t curl up or separate from the foam—even when you shift positions or move the insert. The cover also has a subtle non-slip texture on the bottom, which keeps it in place under sofa cushions (no sliding around every time you sit down). It’s clear this insert is built to withstand daily wear and tear, not just temporary use. Fit is versatile for most sofas: The 17" length x 66" width works perfectly for standard 3-seater sofas, but it’s also easy to trim with scissors if you have a smaller sofa, loveseat, or armchair—no special tools needed. I trimmed a small section to fit my 2-seater loveseat, and the cut edge was clean (no fraying) and blended seamlessly. It fits under most sofa cushion types (foam, fiber, down) without making the seat too tall— it adds just enough height to fix sagging without altering the sofa’s original look. Value for money is unbeatable: For the price, you get a support insert that extends the life of your sofa by years—saving you thousands of dollars on a new sofa or expensive cushion replacements. Similar extra-thick support inserts from furniture brands cost 2-3x more, but this one performs just as well (if not better). It’s a one-time purchase that solves a common furniture problem, making it one of the most cost-effective home upgrades I’ve ever bought. Comfort is a pleasant surprise: I was worried a “support insert” would feel hard, but this one balances firmness with softness— it’s comfortable enough for napping, but supportive enough for daily use. The breathable cover prevents overheating, and the even weight distribution eliminates pressure points (no more sore hips after sitting!). My family and guests all comment on how much more comfortable the sofa feels now— it’s like having a “new” sofa without the new sofa price tag. If your sofa is sagging and you don’t want to replace it, this LAMINET support insert is a must-have. Highly recommend!

This product arrived quickly and the cost was within reason. It was easy to install the support under my sofa cushions, but the panels are not as thick as I envisioned they would be from reading other reviews. The panels are only about 1/4 inch thick when opened and while it provides some support, it is not significant enough to eliminate the slight sag that has formed over time in that part of the sofa.

I don’t leave reviews like this very much but this thing was terrible. I think it lasted three or four days and then it just started busting a falling apart. I do not recommend this product.

After reading several reviews, I was a little skeptical about buying them because there are a lot of negative reviews about this product. However, I'm glad I took a chance on these as they work well for my sectional. Like another reviewer stated, these boards are not for super sagging couches, chairs, etc., and make sure to take measurements before ordering. The only drawback is that I wish the boards were a little wider. Other than that, they work great and make my sectional look brand new.

I am so glad that I took a chance and purchased this support for my sofa. After trying a wooden couch support that was so hard, my butt hurt and foam cushion support that exposed a full inch of foam in plain view (returned all to Amazon), I found this support. It’s absolutely perfect! The perfect fit, the perfect amount of support without feeling hard, the perfect price, etc.

The middle of my couch was sagging, because that’s where I sit on it the most. So I decided to buy one of these, and didn’t want to spend a lot of money. Arrived no damage and it was easy to install because all you do is open the plastic packaging and pull it out. I actually bought one a little bit longer than a standard cushion size and folded it in half and put it under the center cushion. After replacing the cushion the couch did look less sagged, but when I sat on it it didn’t give any extra firmness. When I got off the couch, it did look less sagged after having sat in it, but I still felt like there was little to no difference when I was sitting on it. And this was after I folded it in half, so it was not just one layer. If you’re getting this just for having your couch look like it doesn’t sag, then it works. But if you are looking for a not-sinking-into-your-couch feeling, I’d say try another one and maybe invest a little more money than this.

Works great on my sofa bed couch.

Works ok by itself added wood to make more sturdy and worked great

Restored my lounge to almost like new

If you’ve got a sagging coach, these panels were great!

I got this to help firm up my couch cushions as they were sagging from use. Unfortunately there was no difference across the whole couch but a slight improvement if you used it only for 1 or 2 cushions by keeping it folded up.

Purchased this product based on the description to correct some sag in my couch. I put it on and there was absolutely no difference whatsoever. It does not work. I gave it one star because I had to in order to make a review, not even worth that. I tried contacting the company but no response. I DO NOT RECOMMEND this product or dealing with this company. Save yourself the money and hassle.

Problem with the width too small.
