Copycat Covers were recently mentioned on another thread here and I recalled looking at this thread a couple years ago when I had my X5 observer's seat redone by them. They did a great job, although communication back and forth was not always consistent. I had to send back the skin to fix a problem with the stitched logo and to add a row of stitching to the walk-thru fold-down but they took care of it at no extra charge. I understand they were going through some management issues at the time.
Here's a pic.
