Abstract: When a person is sitting in a chair facing an outdoor campfire, the radiant heat created from the fire can only be felt on parts of a person's body directly exposed to the fire. Other parts of the body not directly exposed to the radiant heat, such as a person's rear thighs and back, will often feel cold in cool environmental conditions. Using the radiant heat generated from a campfire, a flexible sheet with a textured reflective surface, attached to the top rail backrest of a chair and to the bottom rail between the two front legs of a chair forming a curve or an arc under the chair, will reflect the radiant heat in an upward direction warming those parts of a person's body not normally receiving heat. The sheet is shaped to fit between the rear legs of generally any typical outdoor folding chair.
