Leather sofa - looking flabby, needs stuffing - and how to clean?

[SofaSofaOnTheFloor]

I'm not sure what sort of leather our sofa is - it's the sort that you can run a nail along and it makes a mark but if you rub your finger on it the mark goes away. Anyone idea what that sort is called?

Anyhow, we have had it for probably ten years and the finish is a bit sticky and not at all shiny. I've used Lord Sheraton cleaner on it but it looks dry in some places and a bit sticky in others. Does anyone have any ideas how to restore?

The frame is fine, but the cushions are sagging. I know you can send cushions away for new insides to be cut but would rather buy some sort of filler to stuff in. Does anyone have any recommendations?

Many thanks.

“Pull up” or nubuck leather.

Cushion fillings do compress over time and can lead to uneven wear on covers. Depending on the type of cushion you can add polyester fibre padding but tbh I would investigate new interiors; it might be less expensive than you think. Most cushions will be foam wrapped in fibre and you really need expert advice.

Thanks cleaner. Now I've looked carefully they are a bit shiney, so not nubuck I don't think. They naturally scar but in a natural way. Will add pic below as I don't seem to have option now.

Here is picture.
