I would furnish the bench with two accent pillows. If you want to get a bit whimsical you can get a pillow with a sweet saying like home sweet home or something more creative. Above the bench, I would either put a mirror with a statement frame or place meaningful photos in various sizes, in various mismatched frames over the bench at various heights. Have fun with it. Stick in a green frame to go with the bench, print some pictures in black and white and sepia, get 2 or 3 small framed mirrors.
