1. An occupant support comprises:
a foundation providing an inner layer of the occupant support;
a cover providing an outer layer of the occupant support and the cover covers the inner layer of the occupant support; and
a surface heater including
an activation layer positioned between the inner layer and the outer layer, the activation layer is formed into a conductive sheet that is configured to provide heat to the cover and
at least one bus bar arranged between the foundation and the cover and configured to supply power to the activation layer,
wherein a comfort layer is provided between the activation layer and the foundation,
wherein the activation layer includes a nanotube structure configured to provide thermal diffusion across the activation layer and to the comfort layer,
wherein the nanotube structure comprises a carbon nanotube film,
wherein the at least one bus bar includes a first bus bar arranged between the foundation and the cover and coupled to the carbon nanotube film, and a second bus bar arranged between the foundation and the cover and coupled to the carbon nanotube film such that the carbon nanotube film extends continuously between the first bus bar and the second bus bar, and
wherein the first bus bar is arranged to extend solely along a first side of the carbon nanotube film and the second bus bar is arranged to extend solely along a second side of the carbon nanotube film opposite the first side, and the first and second bus bars are coupled to a power source to supply power to the nanotube structure by conducting power, in series, from the power source to the first bus bar, through the nanotube structure, and then through the second bus bar.
