To remove the rear seat bottom cushion, push down hard on the forward edge of the seat, push back, and then lift up. If it won't come out, you can see the retainer wires in the clips if you look under the seat: You can pop the wires out of the retaining clips with a wide bladed screwdriver if the push-n-pull technique does not work for you. The seat back is retained by 2 ea. 7/16" head screws at the bottom of the seat back. Once removed, you slide the set back up to release it from the upper clips.
