Size: 70" x 21.5" - Couch
We all love sinking into a comfy sofa, but nobody enjoys that "falling into a black hole" feeling caused by sagging cushions. Enter the LAVEVE Heavy Duty Couch Cushion Support, a game-changer for saggy sofas. Measuring 20.5''x67'' and made from thick, solid wood, this support is here to save the day—and your back! The LAVEVE cushion support is crafted from thick, solid wood, making it incredibly sturdy. Unlike flimsy plastic or cardboard alternatives, this support won’t bend, buckle, or break under pressure. It’s designed to provide a firm foundation for your cushions, ensuring they stay in place and maintain their shape. Setting up the cushion support is a breeze. Simply unfold it and place it under your sofa cushions. The 20.5''x67'' size is generous enough to cover a wide area, making it suitable for most sofas. No tools, no fuss—just instant support. What I love about this cushion support is its durable material and easy-to-use design. The thick, solid wood construction means this support will last for years. Unfold, place, and enjoy a firmer seat—it’s that simple. The size is perfect for a wide range of sofas, providing comprehensive support. After installing the LAVEVE cushion support, I invited a friend over to test it out. He plopped down on the sofa with the force of a thousand suns, expecting the usual sag. Instead, he was met with solid support. His wide-eyed surprise was priceless. "Did you get a new couch?" he asked. Nope, just a little help from LAVEVE! The LAVEVE Heavy Duty Couch Cushion Support is a must-have for anyone dealing with saggy sofa syndrome. It’s durable, easy to install, and instantly improves the comfort and longevity of your couch. Say goodbye to the black hole effect and hello to supportive, comfortable seating. Highly recommended for anyone looking to give their old sofa a new lease on life!

Just received and I am very pleased with the results. Fits my couch perfectly, was a snap to install and it has given the support needed. I’m hopeful it will last a few years. Easy fix and cost effective.

This product works. My expensive couch is only a year old (le sigh) and I've already had to resort to flipping the cushions. I got this product and it immediately made my couch feel brand new and firm again. The sagging is gone and it's sturdy and the cushions are now the same level as the corner cushions, which are generally not sit on. This is an excellent product that does exactly as it says it does. I've been sending it to friends and family as a result.

Size: 70" x 21.5" - Couch
I bought a sectional off marketplace and it is good overall, but the cushions did sag a bit. I inserted this (which is significantly cheaper than buying a new couch obviously) and the results were so much better. The support is great without being drastically noticeable. The cushions slip a bit, but there is Velcro on the cushion itself, and I could easily apply some to this, so I won’t knock points off for that.

Size: 90" x 25" - Oversized sofa
I bought two of these, the 81 inch and 95 inch, because my couch size was kind of in between the two; neither would've been an exact fit. I was initially going to return one and keep the one that fit better, however, I thought layering them might give extra support since I have a deep couch (although it seems average to me). I ended up putting the 95 inch on the bottom and the 81 inch on the top to get the coverage I needed for my couch. The product itself feels sturdy and I tested them out after putting them on my couch and I can tell the difference. So as of now this product feels like it will be sufficient; however, I'm leaving a three star review due to the fact that I had to purchase two of the product to do the job of one. I wish there would have been more options for the depth of the product, as well as the length so that I could have needed just one. I also will say I browsed for quite a while on Amazon trying to find a similar product that would fit my couch, however it appears other makers have very little variety in their sizes as well, so I don't want to be too harsh with my review.

Size: 72" x 24" - Deep Couch
I rarely write a review because you are often asked to as soon as the item is delivered and I haven’t even used it yet - annoying! I have a 25 year old couch and have been looking to replace it but haven’t found anything I really like. I came across this item and decided to try it out. I took the cushions off and measured. The 24 x 72 should be a perfect fit. It came today and was heavier than i expected. I put it over the springs and it was a perfect fit. I no longer feel like I am sinking to the floor. I just extended the life of my old couch. Hopefully it will maintain its firmness until I replace it.

Works great! We recently bought 2 brand new sectionals with sofa beds we didn’t know having the sofa beds would dip or sag when sitting on the sofa since we never had sofa beds before. I wasn’t sure if this would work since it’s intended for regular sofas. Install is less than 2 minutes and support is immediate! I’m buying another one for the living room.
