Maybe I'm denser than previously thought, but when I fold my back seats up to put my dogs in there, the thing doesn't lock into place... what am I missing or doing wrong? I had to get a bungee cord and run through the locking mechanism on the bottom of the seats to each side of the truck's O-Sh*t handles to keep it from smashing my poor puppies feet!

Here's the poor victims of the back seat problems I'm having. All the want is to ride with me to the park in safety!
