I bought this leather (leatherette?) couch 1.5 years ago but recently noticed that the surface was damaged. Please see the photo below. How should I repair it? Since I bought an "extended warranty" plan, I can try to give the company a call.
There are vinyl patch kits available, most often sold for use repairing car seats. I've had mediocre success with them.
However, since you have that extended warranty, it's definitely worth checking if this is covered first; anything you do might be an excuse to void that warranty. I suspect thst this will be considered normal wear and not covered but ya never know until you ask.
