Deck bench question

Hi. We're redoing the back of our house and I constructed my deck last fall. I was planning on just doing simple railings using 2x2 ballisters connecting directly to the deck wall but ran out of time. While I was on vacation this summer I came across this deck at a vacation house and decided I liked the idea of a bench: Image: http://i264.photobucket.com/albums/ii200/jones_tony/household/CAM01016_zps944a8c06.jpg (http://s264.photobucket.com/user/jones_tony/media/household/CAM01016_zps944a8c06.jpg.html) This is the deck, stairs will be where the red arrows are. In the first photo the stairs will run against the wall (heading towards the back gate):
