It's not designed to come out...easily.

It's designed to just fold into the floor.

Understood.

In case the link doesn't work for you:

Removal

1. With the third row seat folded into the floor well, use trim stick C-4755 or equivalent to disengage the clips (1) that secure the anchor molding (3) to the seat frame.

2. Remove the bolts (1) that secure the front of the seat to the floor panel.

3. Raise the seat to the upright position.

4. Remove the bolts (1) that secure the hinges at the rear of the seat to the floor panel in the sequence shown and remove the rear seat.

Note that it appears to be for the 2005-2007 minivans, but the 2008+ rear seats are very similar.
