  • Sag-Free Sofa: LAVEVE Heavy Duty Couch Cushion Support Review
Size: 21.5" x 70" - 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

  • No sinking but definitely durable and HARD
Size: 21.5" x 70" - Couch
Product came on time as said at time of purchase with no damage to box or packaging basic clear package nothing fancy. Boards they use for planks are very sturdy like said in description. The cloth that encases the boards seems durable and will protect my cushions from being ripped from the boards. They definitely work as described and I'm. Now not sinking into my couch. However it is quite firm now. About to replace the foam in the cushions hoping it helps but beware it's an adjustment. You will feel the difference and it might not be what you want ... show more

Size: 21.5" x 70" - Couch
Only thing I dislike about it when you first put it on it falls through the boards in the futon. Sturdy, firmness, smooth, color is great can find where you put it. Great product!!!

  • Made Of Wood
Size: 24" x 72" - Deep Couch
No particle board makes this very sturdy, but yet has a slim profile. Super easy to place, supports my worn out sofa cushions well. Highly recommend.

  • Couch is like new!
Size: 21.5" x 70" - Couch
I have a hand me down sectional that was well loved before it came to me. The middle of the couches were sagging and I was getting frustrated that there was only one comfy spot. Else you’d start to lean into the center of the divot. At my wits end, I looked up ways to fix this issue and I discovered these! They’re so easy to use and I love that the wood boards are covered so you don’t need to worry about splinters. It’s just the perfect width to fit under the cushions but not stick out. Now my couch feels like it’s new! The extra support has been great and they’re very strong. Probably not recommended but I did walk on the couch and the boards didn’t snap so rest assured your booty will be safe! ... show more

  • Not sure it will hold up
Size: 24" x 72" - Deep Couch
This was a good fit and installed easily, and it will definitely firm up my saggy sofa, but the boards aren't as rigid and sturdy as I thought they would be. I have my doubts about how long this product will hold up. It was a quick, cheap fix though, so it will do at least for a little while

  • Saved us from returning the sofa
Size: 24" x 72" - Deep Couch
Best idea ever to buy this for our brandnew sofa, that was - contrary to the model in the store - with sagging cushions and very uncomfortable. With this couch support we now have the firm seating experience we have been looking for. Great product! Hopefully the boards do not bend over time.

  • Common Sense!! Measure Before You Buy
Size: 21.5" x 48" - Loveseat
Product does what is it suppose to❤️!! Great product. Shop around for the size you need. Don't blame the company because you failed to do your part 🤦🏽♀️. Measure chair🪑 before you buy‼️Common Sense. If your chair was not sagging before you added the support. You will not feel much of a difference. What may happen is with the support there they may cause the chair to sink in. Now you have damaged you chair. There if I fixed your understand of if it ain't broke. Don't fix it. For God sakes don't ever cut it down to size. The way most chairs are made hopefully you will be able to center, have the extra fold into the opening under the arm rest or fold it under the slat next to it. If you cut ✂️ it will not last it will come apart. (As it should.) Some lady did a video review and she made that suggestion and I was like... Don't do that!! She was also the person who's chair was not in need of support and that is why she didn't feel much of a difference. At least she gave the product 4⭐️ 🙄😒. Hope this helps. By the way. These supports may not work for a chair that you know should have been replaced years ago. It is not a miracle maker.😆😄 ... show more
