Same as me. I started on the top-right (between the headrest and the seatbelt when the seat is upright), pried up a corner of that plastic c-channel, and then once you can get a finger under it, you can slide under it the rest of the way. Then did the top and then the left edge the same way. Carefully worked the leather off of the top-right corner, without damaging that corner stitching. Then you have some slack, shift the cover over and the top-left is easier. Figured out the black plastic rings that the headrest slides into, you can get a finger nail under one of the small tabs, then it comes right off. The actual " black tubes" that go down into the seat stay on, there's enough wiggle room that the leather can stretch over it and off.
If you need to go further than that and mess with hog clips, or take the whole seat-back off.... good luck!
