Product Trend Furniture Fix Steel for Chair, Sofa, Loveseat, Mattress, or Couch-Cushion Support, Supercomfortable Nonslip Adjustable Seat Support, Extend Furniture Life, (66 x 17) Inches Deep (Black)

Bought for a friend who had the plastic set b4. They really like it. It fits the whole couch perfectly. I did measure b4 ordering. I have sat on it a great difference

I've only had it for about 15 minutes, but the fact that I'm able to sit ON my couch instead of IN my couch has made all the difference! If it lasts for at least 3 months it'll be well worth the investment for me.

Okay product!

Haven’t had it a month and it’s already breaking

Well I thought it was going to be bigger than it actually was it's definitely longer it is non-slip but not very sturdy so I think I have to find something else for my height a bit to stop sinking in when I have it in couch form. So my search continues

Makes a difference in my chairs now it sit u up better

It didn’t completely prevent my sofa from going down but it does help and is a great temp fix before getting a new sofa. Recommend this one because the others I brought did nothing.

I’m not sure how this is supposed to be wide enough… the bars are supposed to sit on the frame of the couch but the bars are not nearly wide enough to make it from each side of the frame. There are no instructions, which means it’s simple but there’s literally no way this can work on my couch. My couch is a normal size… so not sure. I wanted this to work so bad- unfortunately nope.
