Sofa pads

[Goodwitch9]

I have an old leather sofa. The seat pads, if that's the correct term, are knackered! One is ripped and the stuffing is coming out, the other had something spilt on it and I can't get the smell out. Until I can afford a new sofa, is there somewhere that sells replacement seat pads/cushions? It doesn't matter if they're not leather as I use stretchy seat covers over them anyway. Thanks!

I've seen some on eBay but don't know if they are thick enough.
it might work getting an old sofa from Freecycle or a second hand site, to use the seat cushions and discard the rest of the sofa.

Ask an upholsterer if they could supply you with just the foam for the seats. Ordinary foam will not be firm enough . Also you could have new cushion covers made/make them yourself. Velvet in a similar or contrasting color looks great on old leather arm chairs/sofas.

I have seen foam for sofas in The Range.
