I'm not even remotely a heavy person-- aka not obese and happen to be female so not even as much weight as many of my male counterparts who own these cars. The rest of the seat looks new still btw. No indentations evident, etc. I've been driving for more years than I care to admit. I've lost count how many new vehicles I've bought (both with vinyl and leather and even cloth seats) and this has never happened to me before like this- not even with 6 years old and 75,000 miles. This is just over 1 year old and I don't even wear jeans or anything that could be sharp to cause this. I've honestly been living in sweats for the most part (so nothing sharp at all, no buttons, zippers, etc.) Even the skirt I wore to a funeral recently had nothing that could cause this. I have no knee, back or hip issues so getting in and out of the car is never a problem.
