    • Better Than I Expected It Really Works!!!
Size: 72" x 24" - Deep Couch
Review Image by Reese
I was honestly skeptical before buying this, but I’m shocked at how well it actually works. My couch cushions were sinking in the middle and starting to feel really uncomfortable. As soon as I put this underneath, it made a noticeable difference right away—the cushions feel much firmer and more supportive. Installation took maybe a couple minutes, nothing complicated at all. It’s also sturdy enough that it doesn’t slide around once it’s in place. It’s not going to make your couch feel brand new, but it definitely improves it a lot and makes it comfortable again. For the price, this is 100% worth it and way cheaper than replacing a couch. I wish I bought it sooner. ... show more

    • No more sagging cushions!!
Size: 70" x 21.5" - Couch
I honestly wasn’t expecting such a big difference, but these support boards completely brought my couch back to life. The cushions used to sink in and feel uneven, especially in the middle, and now everything feels firm, supportive, and comfortable again. Installation took just a couple of minutes — literally unfold and place them under the cushions. The boards feel very sturdy and well made, not flimsy like some cheaper options. They stay in place nicely and instantly improved both the comfort and appearance of the couch. It even helped with back support while sitting for longer periods. For the price, this was an amazing upgrade and saved me from replacing an expensive sofa. Highly recommend to anyone dealing with sagging couch cushions! ... show more

    • Works really well, stopped the sagging
Size: 23" x 21.5" - Armchair
I find that these support boards work really well. We have a sectional sofa so I bought 2 loveseat sizes and one arm chair size. Fits perfectly, easy to install and doesn't show at all. I thought they would be very heavy and thicker too so I was a little concerned but they did the job I was looking for. I noticed a difference right away. Fixed my sagging cushions, very pleased with this product! ... show more

    • Very good product
Size: 70" x 21.5" - Couch
This support board worked very well on my old couch. It’s still in good shape cosmetically, but it’s a sleeper sofa and the cushions had started sagging toward the back and became uncomfortable to sit on. This support board solved the problem! It worked so well, I ordered another one for the matching chair. ... show more

Most people are trying to preserve an old sofa. In our case we're trying to recover from purchasing a brand new sectional (30 days no return). It's hollow and has no support under the cushion. The Heavy Duty Couch Cushion supports boards give the sofa the support and durability that it should have had originally. The durability, width and length provide excellent support. Thank you for saving me a trip to Home Depot for a piece of wood that would probably cut the material eventually. ⭐⭐⭐⭐⭐ ... show more
