I think the problem with sports seats that have fairly prominent side bolsters is that any universal / generic seat cover is unlikely to be a good fit - it’ll probably be quite baggy / saggy and will look a bit like someone’s but a bin liner over the seat - like this (and that would really play havoc with my car OCD
);
If you want good fitting seat cover, then you may need to consider getting one custom made, which I dare say won’t be cheap and there’s a chance it’ll still not be a ‘perfect’ fit. Also, it’s important to ensure any seat cover is airbag friendly, so that if you are unfortunate enough to be involved in an accident, the seat airbag isn’t prevented from deploying correctly and potentially causing the seat occupant an injury because of the seat cover.
