Simple question, and i feel stupid for asking but, how do you get the headrests out? I pushed the little button in and it will not come all the way out. I have a 2018 so i dont know if they changed the design so they cant be removed without taking the whole seat apart. I coulda swore I had one of them out already but put it back when I saw the notches were only on one side so it wouldnt lock if turned backwards, but now nothing I do will let it release from the seat.
