Covercraft Custom Seat Covers

I bought the used option to save a few hundred dollars since I didn't care that there might be staining (as stated in the description) when I was putting them on to prevent staining by my kids. I tried to install this seat cover on my split/bench second row seats. I don't know if I received a different model but I was excited to see that there was a cut-out for the fold down armrest between the seats that wasn't depicted in the pictures/description. As I proceeded to install while figuring out the pieces I was sent, I realized that there was no cover for the hole allowing the arm-rest. I assumed there would be a velcro window or something similar I had to add on later. Looking at the pictures in the instructions it did not seem that I was missing the piece but that there was just a open window in the middle of my back seat. I wanted the canvas waterproof seat covers to protect my seats from the kids after swim practice and when we hike or climb and an open window seems to defeat the purpose of putting them in.If there wasn't a large (about 12" x 16") hole in the middle of the seat cover these would have been awesome. They looked well made and fit snugly on the bench seat back. I wish it worked out.
