Left marks on my tan leather seat
I really liked the cushion until I removed it when I was cleaning my car. The rubbery side of the cushion cover left black marks on my tan leather seats. It was only in the car for about a month, and I was not using the seat heater.  I couldn't get them to wipe off. I've stopped using it, but it's past the return window. Maybe I'll use it in a car with dark seats or on my desk chair. I guess you could put another piece of fabric between the cushion and the seat, but I'm afraid it will slide around.
