To remove the rear seat
The way I do it is to get into the back seat and position my self in the fornt center of the seat in a kneeling poststion looking out the back glass.
With the palms of my hand slightly strecthed from my sides I put them at the bottom of the lower cushion (SEAT) and push in towards the trunk, as it moves back lift up on seat and you should fill it release. The seat is hooked to a couple of brackets
Once you have the lower cushion out then look for two bolts under the top cushion. I think you need a 1/2 Socket to remove the 2 bolts. when bolts are removed then that portion of the seat will lift up and out.
