Covers fit really well and appear like factory made. I have heated and cooled seats so the cooling function will not work with the the seat covers on. The heaters take much longer to feel heat in the seats but the sheepskin covers don't feel cold even the coldest days. The side bolsters don't feel as deep after the cover is installed because of the thickness of the covers so my seats don't feel like they hold you as nice as without the covers. Other than that, very ice covers.
