Our two year old girl decided to sit on the armrest of the passenger side middle seat the other day and it broke... I can pull it out, I can see where it was welded on (kind of a weak design - then again, I guess it's not designed to withstand that kind of abuse) but I'm not sure how to or if I can repair it. I can see a zipper on the back of the armrest which I'm guessing would allow me to take the padding off the metal part, but I can't seem to figure out a way to get that thing unzipped. Any and all ideas/suggestions are greatly appreciated.
