Rear seat cover

[marcesq]

I bought the Universal Protective Rear Cover (PN: 52 30 0 418 652) BMW Accessories - 2011 X5 xDrive 35d SAV:Universal Protective Rear Cover

However, when i went to install, nothing really fit that well, and the covers did not cover the head rests. I figured they had just mislabeled the bag, so I had them reordered... after another try and a phone call to the distributor/warehouse, I was told that's all there is and I was SOL. I'm not convinced I was given the correct item, but the part number on the bag matched up perfectly.

SO, I need a rear seat cover solution for my two small dogs. I tried some cheapos from Petsmart, but they weren't big enough.

Anyone have any suggestions?
