Simples - you adjust the headrest prior to putting on the covers. I've never had the need to adjust the headrest further thereafter.How do you adjust the headrest?
Not for me. Doesn’t look “fitted” or tidy.
As to not looking fitted, my Gren's a workhorse not some show piece - the covers fit, don't move around, and do their protection job at a great price. If it were otherwise, I'd be very happy just with the leather.
