The purpose of this study was to determine the effects of the presence and characteristics of a neck pillow on head and neck posture in the resting sitting position with eyes closed. Sitting posture maintenance tests were conducted on four subjects using a middle-back office chair. The head and neck postures in the normal sitting posture and in the sitting posture with two types of neck pillows were recorded for 15 minutes with closed eyes. The motion amount of the center of gravity of the head and neck was similar among conditions. However, the variation of the center of gravity position of the head and neck throughout the test tended to be smaller when a comfortable neck pillow was used.
