A seat cover for an automotive vehicle which has inflatable, transversely extending columnar portions for providing support to the seated individual, especially to the lumbar region, and heat-retaining portions, filled with a heat-retaining agent such as polyethylene glycol, interspersed among the inflatable columnar portions for accumulating ambient heat derived from sunlight and for giving off said heat when the ambient temperature drops. Means for inflating the columnar portions manually are provided.
