Provided is a polyurethane foam which, when fitted to a human subject, exhibits excellent shape-following properties while exhibiting excellent comfortableness even during movement and when at rest. The polyurethane foam has toluene diisocyanate and polyether polyol as main components. The glass transition temperature, which is set to the temperature corresponding to the loss tangent peak value, is in the range 0°C-40°C inclusive. Under temperatures in the range 0°C-40°C inclusive, the loss tangent in the frequency domain 0.1Hz-100Hz inclusive is at least 0.4. The average value of the loss tangent in the frequency range 0.1Hz-1Hz inclusive is equal to or less than the average value of the loss tangent in the frequency range 10Hz-100Hz inclusive. |
