It's a weak point on 206's (and 206cc's). Obvious place to start is the scrapyards - find one that's been written off. Get a seat and transfer your seat covering to it.
Personally, I'd consider drilling and bolting the existing seat in one position on the runners.
However, with the car so new the Peugeot dealer's discounted offer looks attractive too.
