Looks like it would be a nice option to replacing the console. My only concern would be the bracket for the hinge, and how it sticks out on one side. Kind of forces whomever sits there into the driver's space. Either that or sit with the hinge digging into their right cheek. Granted that person is likely to be small. The other problem I see with it, is the cup holder. So now the person who sits there, which is likely a child will have their legs all over the place. Since kids do this anyway, and rarely can sit still, this would only encourage it more.
As for making it part of a booster seat, that would work pretty well. Maybe a 5 point harness too.:tongue:
