A mattress or pad that contours and conforms to the body profile of a reclining individual. The preferred embodiments contain flexible, airtight chambers, at least two of which are interconnected to allow the transfer of air or liquid. Interconnected chambers are positioned and dimensioned to conform to and support the natural curves of a reclining body. The volume of fluid, e. g. , air or liquid, within all of the chambers can be easily adjusted to allow comfortable resistance and conformity to a wide range of body lengths, weights, and shapes. Preferred embodiments have insulative, self inflating elements, comprising low-density, open-celled, flexible foam in a rectangular configuration, in a thin-walled cylindrical configuration, and in an arced configuration determined by an adhered heat-reflective plastic film.
