Problems With S-Max Front Seats

[matphoto]

Hi I have an S-Max Zetec 2ltr Automatic, and have a problem with the front seats, in that tha padding in the raised sides collapses and you end up sitting on the frame, which is really uncomfortable.

This has happened twice up to now, first time Fords took it in and replaced the padding. Second time within three months they replaced the seats, and now after nine months it has happened again.

Has anyone else had this problem or is it not common?

Thanks

Mat
