21.5" x 70" - 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

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!

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.

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!

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

⭐️⭐️⭐️⭐️⭐️ 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!

The boards are listed as "extra thick" and look that way in the product page photo, but in reality are about half that. The product would be better if it was as described.

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

Being 25" deep, this sofa support is great for my old 3-seater sofa. The boards are thick solid wood and should last for years.

We have an older leather couch and the cushions were getting soft. I love the look of the broken in leather and didn’t want to change it. This under cushion padding worked perfectly , the cushions feel nice and firm like a new couch. Really happy with this purchase.

Funciona perfecto, tenemos un sillón largo largo que necesitaba repartir el peso y este soporte lo arregló por completo. Llegó un poco roto de la funda, pero es funcional así que nos lo quedamos así, pero perdió una estrella.

Gave my sagging couch great confidence! Rejuvenated my 14 year old couch! Eliminated couch-diving guilt!
