Saggy bottoms

[JumboBeef]

My Volvo C70 is ten years old with 115,000 miles on the clock. Only two owners but the second owner (who did 50,000 miles) was built like Dawn French and so my driver's seat isn't as pert as it should be.

Anyone ever resprung a seat? How hard is it to do? Is it a DIY task or should I take the car somewhere?

Thanks.

Might work out cheaper to get another from a scrap yard.

Thanks, but almost impossible to get a matching leather seat (and it will cost £££).

Has no one ever tried respringing?
