Abstract
To examine sitting comfort is important to decrease fatigue due to long-term sitting on the train seats. We focused on leg swelling which occurs during sitting, and investigated it with use of both bioelectrical impedance method and sensory testing. Sitting experiment was performed by using four kinds of footrest angle, three kinds of cushion firmness, and two kinds of experimental timing (AM or PM). From the results, we found that leg swelling decreased while sitting under the condition of 30 degree for footrest angle. It is considered that there is an appropriate combination of footrest angle and cushion firmness.
