Sagging Couch Support Under Cushion Sofa Seat Saver Fordable Support Board for Sofa (21''x 16'')

Actually bought these for our patio chairs. They're in good shape, just needed a little more support. They worked perfect.

The product is smaller than I imagined. My mistake for not verifying the measurement ! This is probably more suited for a small chair, or child-sized furniture. It's not the strongest product either. It seems like reinforced cardboard covered in thin plastic. Save your money.

It works as stated to fix sagging couch cushion….but only big enough for ONE cushion. Read specifications carefully

They worked pretty good, but I would have to double them up to make the cushions firmer. The couch isn't very old (under two years) but used daily, so the cushions were sinking some. I think they're a little on the expensive side, as I need four sets to span the length of my couch, so I probably will be getting a piece of plywood instead and try that. It's cheaper and I heard it works well.

They are so much thicker now!!!

Sturdiness support fit value for money comfort support

They don't fit end to end, not worth the money

I had my doubt as to whether these supports would provide in my sagging 3-year old couch cushions. I bought three of them, one for each of my couch cushions. They easily slip in between the couch and the cushion. After three week's of using the couch daily, I am pleasantly surprised to report that while sitting in my couch, they support my hips and low back minimizing any discomfort I was feeling prior to having them. While they don't change the sagging cushion per say, they do change my experience in sitting on my couch. For this reason, 5-stars makes sense.

Works perfectly! No more sinking feeling in an otherwise perfect chair.

adds some support

This product is excellent and stopped the sinking feeling when sitting in a sagging chair.

Bought these to try and fix the sagging on the most used side of the couch. Did not make a difference whatsoever. Don't waste your money.
