I have to create a substantial number of animations of a figure seated in an office chair.  Currently the chair is just a compound prop with a base as the parent, and the seat, seatback and fives coasters as children.  I would like to be able to create pose files for my figure, and would like them also to affect the chair.  I don't want the chair to be the child of the figure, as it would be hard to maintain placement on the ground when the figure is being posed.  I'm thinking the chair may need to be converted to a figure before pose files can be applied to it.  Does anyone have any experience with this?
