Courtenay, Here's a picture of mine and an ebony stained one I made for Mike Bouse, who gave it to his wife to go in a car with black interior. This is a rear view:

It doesn't attach. I made it so it is a snug fit between the seats. The curved leg matches the tranny tunnel and keeps it level and stable. It isn't a solid mount, but it could be if I wanted to. I wanted to be able to easily take it in or out. My car has the factory leather padded console and doesn't have the bulge at the rear of the e-brake handle. To use my pattern on a standard console a couple of foam rubber pads would be put on the front, so that the bottom of the cupholder/armrest is not rocking on the bulge.
