    • Very good Cushion Support

    • Excellent product that TRULY works!
Size: 72" x 24" - Deep Couch
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. ... show more

    • Measure your furniture before ordering
Size: 72" x 24" - Deep Couch
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.

    • Good investment! New life for my furniture.
Size: 70"x21.5" & 48"x21.5"- Sectional Couch
We have a loveseat and sofa that are in great shape and look good, BUT they had gotten too saggy under the cushions. I figured it would be worth a try to see if these would help. I bought the supports on a sale day and it was worth it. They have made a big difference in the comfort. You no longer feel like you are falling down in to our furniture. They don't show and look good even when you pick up the cushions. It looks like the black cloth that was already under the cushions. On my furniture they fit on the supports under the cushions perfectly and seem sturdy. ... show more

    • An amazing product!
Size: 70" x 21.5" - Couch
It has to be amazing for me to leave a review. Oh my gosh, one of the best purchases ever! We have a leather sofa that has been loved on for years. It still looks in great shape, but next to no support when sitting on it. Took a chance on this product and it has totally changed how it feels. I can't get over the difference it makes! The support is incredible, from saggy to firm in minutes, it feels like new. Can't recommend this product enough! ... show more

    • Sag-Free Sofa: LAVEVE Heavy Duty Couch Cushion Support Review
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! ... show more
