Those sheepskin covers give me the willies! I can't see where the side airbag is allowed to deploy - it seems to be covered. If it is, that is a real safety concern.
The sheepskin covers I had on my previous Subaru Forester were completely open along the sides. By the way, if you want some real sheepskin covers made in New Zealand, sheepskinstuff.com in Vancouver would be a good place to look. They ship to both U.S. and Canada. You really don't need to switch on the seat heaters even on a freezing cold winter day with those to sit in.
As for me, the seats of the GT CX3 are one of the things that prompted me to buy. They are insanely great and instead of transferring the sheepskin covers that I had on my Forester into my CX3, I passed them on to one of my kids.
