Works well at firming sofa. Not as good as a new sofa, but then I wouldn't expect it to be. Has added extra life to current sofa till I decide on what I want. The product arrived well packaged and size was accurate. I will by another as sofa is L shaped so would need 2.

Its seems to help firm up a saggy sofa. All fitted and feeling the sofa has a few more years in it. Will see how it performs. I like the cover has rubber spots, which reduces the slippage, appearance is good, and it’s good you can unzip the boards so you can wash the cover. Seems to perform well, and offers good support and comfort.

Really firm, does the job

Expected this to be much more sturdier and thicker,has made a slight difference but not a massive one.ths length does fit a 3 seater sofa perfect.so shall see how long it lasts although don’t expect it to last long unfortunately.

Brought for my 7year old sofa that had started to sag, the difference is amazing. Not only can you sit comfortably but the look of the sofa is improved as the cushions don't visibly sag tooWill definitely be purchasing more

Seemed good at first but after a few days the bits of ‘thick’ and ‘strong’ wood boards broke. Im quite disappointed as it’s an expensive product, functioned for about a couple days but then started breaking. What’s the point…

My sofa was beginning to sag badly, these have made a massive difference, And they are quite good quality.

I purchased this along with some foam to increase height of sofa as it was sagging. Great size, did think it looked thicker in your picture of it.
