Looks great, and I was considering some seat covers myself. Thanks for posting the link!
In my experience, though, the material of these seat covers always feels very cheap and uncomfortable, and that has made me steer away from using them. That being said, I am bald, and one thing you quickly learn after going bald is how greasy your scalp is. It's pretty gross, actually. In cars with leather seats, you end up leaving greasy smudges on the headrests.
Because of the above, I was very worried about the cleanliness of the headrest in my Mirage. If any other baldies out there are in a similar situation to me, be aware that cloth sleeping caps and knitted hats are actually the perfect size for putting over the headrest, and can be found in pretty much any material/color you want.
I use these, as the cotton is very comfortable on my head. It's easy to take off and wash at the end of the week, as well.
