I have never seen such a material. Also the seats backcover is different from the known seats, I think.
In Xedos 6 series 1 in Germany we only had leather seats in light beige or in anthracite or the cheaper variant with classic light grey fabric cover, similar to the 80's Mazda seats - your seats are looking completely different.
So, just try the
Xedos-Infotool, type in your vehicle identification number (VIN) and see, when and for which country this car was built.
