If you look under your seats near where the seat pedestal bolts to the seat you should see a paper usually stuffed into the springs. This is the flexsteel model.
Each seat has one that list model number, covering type, color and numbers specific to that seat. With that info you can get a seat cover from flexsteel
That matches exactly what you have. Several years ago I got a set to completely cover my seat including the alpine embroidery. Took it to upolstery shop and had it installed
