Abstract
A polyurethane foam having excellent shape-following properties, which exhibits favorable comfort when worn on the human body, both during movement and at rest. The polyurethane foam contains a toluene diisocyanate and a polyether polyol as the main components, has a glass transition temperature, defined as the temperature corresponding with the peak value of the loss tangent, of not less than 0° C. and not more than 40° C., and in the temperature range from not less than 0° C. to not more than 40° C., the loss tangent in the frequency range from not less than 0.1 Hz to not more than 100 Hz is 0.4 or greater, and the average value of the loss tangent in the frequency range from not less than 0.1 Hz to not more than 1 Hz is not greater than the average value of the loss tangent in the frequency range from not less than 10 Hz to not more than 100 Hz.
