Sagging driver's seat

[Tandrup]

Hi there,

I have been working on getting my '03 Boxster reconditioned back to good condition and I am about to re-color the seats.

However, I have an issue with my driver's seat where the seat cushion is sagging (see the attached photos). It's like the cushion has been pressed down - it is exactly the spot where you would typically "hit" the seat first with your "backside" when you get in. It has been like that for as long as I have owned the car and it isn't necessarily uncomfortable, but now that I am about to work on my seats I wanted to see if anyone has experienced anything similar and/or have an idea on what could be wrong and potentially how I could fix it?

Thanks,
Lars
