17" X 66"

Good quality and a bit bigger than most so ok for our 3str which is fairly new and has chunky cushions, we probably should not have bought a very soft but very comfy sofa!! But now all is sorted.J P

This product is ok . It does strengthen the sofa soIt doesn’t feel as soft when sat on it . But it’s a bit flimsy .

The right size fitted well however, Not strong enough.

Actually performing better than I thought. Bought one for a new daybed I have - it’s got 2x memory foam mattresses. Put this in and you can sit comfortably without sinking. It is quite narrow though and the bed is wide - so I may buy another and use 2 next to each other.

The quality is not great. It's weak and narrow in size, not wide enough.

Like many reviews already here, that I wish I would have read before buying, I was surprised at the tiny size. Also like many others, I should have paid better attention to the measurements. The product actually looked laughable on our 2 seater sofa, and didn't make a difference to the sagging. However, only one end of the sofa was sagging so I folded the item in half and used it anyway, rather than return it. Sorry, but from my point of view, I wouldn't recommend, because it doesn't function as it should, so definitely was not a good value for the money. If you have a very small sofa, it might work better for you.

Bought to enhance the setteee and provide a solid base great price easy to fit long a lasting.

Pretty much does the job, extending the life of our 24 year old 3 seater. Dimensions could be a tad more generous but overall, quite adequate.
