Hi guys, new to the forum here, and I would just like to point out I am 100% new to anything car related. Basically, I've got some new car seat covers, but to get them to fit properly, I need to remove the rear seats (bit you sit on, not so much the back part). I've tried pulling it up which unhooks it from the base, but then it doesn't wanna move anywhere. Do I need to do anything specific, if so with what tools? Remember complete noob here. Everything in lamens terms!
