A scale comprising: a chair that includes a plurality of legs and a seat, one or more of the legs being tubular; one or more load sensors and a mounting arrangement that attaches each load sensor to the chair in a fixed position, each load sensor being disposed entirely within one or more of the tubular legs such that each sensor directly or indirectly receives loading that would otherwise be received by one or more of the legs and transmits the received loading to one or more of the legs; and electronic circuitry that processes the signal or signals from the load sensor or sensors, or signals related thereto, and provides a signal related to the loading of the chair; wherein the scale comprises a weighing configuration and a non-weighing configuration, and wherein the mounting arrangement comprises a cover within which the load transmitting member is mounted, the cover having an extending non-weighing position in which the load transmitting member does not extend therefrom and the cover is adapted to contact the supporting surface and provide support for the leg of the chair to which it is attached, and a retracted weighing position in which the load transmitting member extends therefrom and is adapted to contact the supporting surface.
