Those are the original perforated seats that were discontinued about a year after the MX was released. It looks like it's peeling because of friction from going in and out. I have the perforated (and cooled) seats that were briefly re-introduced on the P100D in mid 2018. They changed the design to prevent the issue you're experiencing by not perforating the side bolsters. 2 years and almost 50,000 KMs with no tears.
