    • Couch cushion
Size: 72" x 24" - Deep Couch
Worked awesome on the sofa. Made it feel like a solid sofa and when you sit it holds you up. We used it on a sofa bed. This is an awesome product to have

Size: 70" x 21.5" - Couch
This is a really great product. Fit perfectly on my couch and the support it provides is fantastic! It's a night and day difference!

    • 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

    • 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

    • Support
Size: 81x 24" - Deep Large Couch
⭐️⭐️⭐️⭐️⭐️ Brought My Couch Back to Life! I was honestly ready to replace my entire couch because the cushions were starting to sag badly — but this support board was a total game changer! It took just a few minutes to slide it underneath the cushions, and the difference was immediate. My sofa feels firm and supportive again without being too stiff. The material is sturdy and doesn’t bend when I sit down, plus it keeps the cushions from sinking into the frame. It’s like sitting on a brand-new couch! If you have older furniture or sagging cushions, this is a super affordable fix that really works. Highly recommend — it saved me hundreds of dollars on buying a new couch! ... show more

    • Stopped My Oversized Love Seat From Sinking
Size: 48" x 21.5" - Loveseat
Excellent product; it immediately changes the support of the love seat. I had a sag in my 13-year-old love seat that is in otherwise excellent condition outwardly. No assembly is required; simply remove cushions, unfold the support, and insert. No cutting or measuring required. I wish it had 2-3 more supports for my oversized love seat, but otherwise a solid solution for sagging sofa supports. Great price and adds years to otherwise good older furniture pieces. ... show more

Review Image by A valid user's wife A valid user's wife
The product works as expected. But the packaging is slightly disappointing. Open the Amazon box (see picture) and what I found is the product wrapped in an old (not sealed) plastic bag. The only brand name to ID it's the thing I ordered is a one-inch sticker on the bag. The fabric looks not impressive also. Let's see how long the fabric can hold with daily usage. ... show more

This worked very well on a 10yo sectional sofa where one seat was sagging. Feels solid, like new.
