I had the same problem, but instead of cutting the seat cover, i cut those plastic pieces off. Just raise the headrest as far as you can, pry the plastic down away from the headrest as far as you can by sticking a long screw driver or something in there, and I just used a metal cutting disk on a rotary cutting tool, Like a dremil. Just be carefull and wear safety glasses, because that plastic goes flying and there will be a little mess to clean up, but its not bad at all
