Comfort and Support Values of Different Pillow Designs

"A pressure mapping system (X3 SENSOR PX 100:64.160.02, X-Sensor®, Calgary, Canada) was used to record the pressure distribution in mmHg of the head and shoulder section \[18,19\]. Pressure distribution was recorded for 1 minute for each lying position. The purpose of these measurements was to describe the pressure distribution created by the participants in the pillow and the supported areas, as well as to find out the differences that may occur between the pillows. Lower pressure values measured by the device were defined as high comfort, while more contact of the head area with the pillow was accepted as high support."
