    • 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

    • 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

    • 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

    • 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

    • Wow-can’t believe the improvement.
Size: 70" x 21.5" - Couch
Sitting on the sofa as I review this and can’t believe the difference in the comfort. Easy installation and perfect fit plus it was on sale and delivery was 2 days early!! Raised seating level at least 2 inches. Seems to be very stable construction and hopefully will enjoy it for a long time.
