Heavy Duty Couch Cushion Support for Sagging Seat 20.5''x81'', Thicken Solid Wood Sofa Under Cushions Boards,Perfectly Fix and Protect 3-4 Seat Couch, Extend Sofa Life

Easy to put down, heavy duty enough to extend the use of our couch a few more years! Holds up to the weight of my 250lb husband, so 👍👍!

My couch doesnt look cheap as the seat doesn’t slouch and looks always firm but soft

Wish I would have found this sooner. This is the perfect solution to saggy and old furniture cushions. I’ve been putting off reupholstering my 25 year old couches due to price. The cushions were thin and uncomfortable. Now with the board I have had friends and family ask who redid my furniture. A few new slip covers and this made my couches like new. I bought more of them for our new rec room sectional so the cushions don’t wear down as fast. I love the support it gives without anyone noticing.

This panel for couch cushion support was great. It has made a huge difference on my couch. I would always sink in and had a hard time getting up. Now it has made it super easy as if the cushions were brand new. Love it

For years my husband would put plywood under our couch cushions to keep them from sagging. Now we’ve found this product and are shocked by how well they work. We’ve now bought 3!

It’s light, easy to install and works great

Was wider. Just didn't work for us and had to return it.

Just got it so cannot speak to longevity; but it fit across the length of my sofa just as described. Only thing I would have preferred is an option for a wider version as it does not match the depth of my cushions- or an option for a narrower one to fill in that extra space, perhaps. That being said, it definitely restored some firmness to the seating. No regrets yet.
