A production workbench is associated with a production cart which is mounted on castors to be movable from one work station to another. In a preferred form, the bench is provided with a slot or cutout to receive the production cart. Inter-engaging guide track apparatus and rollers are provided between the bench and the cart operative to serve as self-leveling apparatus to bring the surfaces of the bench and the cart to the same level when the production cart is inserted into the cutout.
