I've noticed that on my 1998 C280 that the "felt" liner near the right rear headrest is starting to bubble - on the side where the seatbelt retracts into. The fabric seems like it is coming unglued from the panel it is attached to. I'm really suprised that it's coming off so soon. Is there an easy way to take off that trim panel and reglue the fabric back down? Or should I take it to a car upholstery place?

Cheers,
Geoff
