  • Glad I found these
Size: 48" x 21.5" - Loveseat
We have a love seat and couch in our sunroom which are of good quality. However, the straps got stretched out from young children jumping on them, and the seats sagged so that they were no longer comfortable to sit in. I saw these and decided to try them. To my delight (and surprise) they not only work well, but were very easy to install. ... 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

  • Works well for old couches you still love!
Size: 72" x 24" - Deep Couch
This works great for the couch that puts my husband to sleep within 10 minutes anytime he lays down on it. It fit perfectly, of course I measured first. It adds support and has pretty much ensured that the couch will be around until the end of time. It's worth it if there's a couch you just can't be parted with. My husband is happy, that makes me happy. I didn't give it 5 stars because the cushions do slide off a little, but not a lot, it's not a big deal. ... show more

  • Everyone needs this !
Size: 70" x 21.5" - Couch
I would give this 10 stars if they offered! My couch is in good shape but was sagging because the inner springs were getting old. Love the couch but it had been particularly uncomfortable to sit on due to sagging. This product gave me back my couch which I love and wasn’t willing to part with it. My inner length on my couch was 66 inches x 19.5inches. No assembly required. I just folded over a few planks and it worked perfectly! This is extremely well made with solid wood slats inside the non removable cover. There will be NO sagging due to its construction! Every couch and side chair should have one! No more leaning or sinking in the seat. This has made my bad back very happy! Well worth the price I paid !w ... show more

  • Perfect fit and support!
Size: 81x 24" - Deep Large Couch
Great product. It’s rare to find something that fits a long, formal sofa so perfectly without needing adjustments. It gives my vintage piece exactly the stability and support it was missing. Simple to use and exactly as described—no extra boards required.

  • It really does make it more firm!! Love it!
Size: 81"x 30" - Deep Large Couch
This worked great on the slouchy couch my daughter gave me! Much more comfortable! Easier to get up! Very happy with my purchase!

  • Overpriced fancy slats, thinner than the picture
Size: 72" x 24" - Deep Couch
These are nothing but fancy slats. The wood is half the thickness you see in the second picture. This will not raise the cushions. It just converts the base into a flattish bench on which you will put your sagging cushions back. Sagging cushions will still sag as this does not provide any additional cushioning. I give it 3 star for overpricing, over-marketing and using inferior materials. ... show more

  • Strong, well made perfection
Size: 70" x 21.5" - Couch
Perfect solution for our Broyhill sleeper sofa. Broyhill is built to last and not easy to.fi d any more. It's ten years old and like new except for the sagging pillows. We replaced the mattress with a thicker, better model but that didn't resolve the issue. We purchased this product hoping for a better resolution for our problem, and this was perfect. My couch is 65 inches wide from arm to arm, we purchased the 70 inch and it worked out great. It was one slat too wide, so we simply folded it over and the fit was perfect. I highly recommend this product! ... show more
