A research on effect of pillow height on pressure and comfort of human body’s prone position

Abstract

This research has explored the effects of buckwheat pillow at different heights on the body pressure distribution and comfort of women aged 44– 64 years. A total of 19 women aged 44–64 years (who are healthy and have no sleep disorder or musculoskeletal disease history) were selected. The quality of sleep and the use of pillow were investigated by questionnaire survey, and subjects were guided to make subjective comfort experience evaluations on the mattresses with moderate hardness with the use of buckwheat pillows at four different heights (the pillow heights were 3 cm, 7 cm, 11 cm and 15 cm, respectively) Laboratory measurement was carried out on body shape index. The body pressure distribution in supine position was also measured. Based on the experiment results the test results of Body Pressure Distribution and Subjective Comfort Evaluation are concluded respectively.
