How do I fold down bench seat

lever on drivers side and passenger side at bottom of backrest where it makes the 90 degree angle to meet the seat should be black.

The mechanism doesn’t feel like I would expect. The design of the one on my pickup is kind of a horizontal rectangle that sort of feels like broken plastic, depresses somewhat finicky sometimes. Thank you for the post!

There should be a little metal lever on the bottom of the back bottom corner on the passenger side. You pull it up with your finger and it should go down.
