MB tex or leather? on the rear seats of my 21 year old w124 i had a tool box on the rear seats that had the four corners dig into my mb tex. I was sort of upset to see what i've done so i decided to leave it alone, instead of making it worse. I came back the next morning and there wasn't a single trace of where the indents were. Very resilient material! If it doesn't go back on its own however, i'd do much more research before trying a self repair. heating the material would make it stretch, and the theory behind the damp rag is to make it quickly retract, thus tightening it. In theory it should work, but i don't want to make anyone responsible for this not working, so i'm going to say don't do it haha
