Sam’s wife was troubled by the high temperature in summer and could not sleep comfortably, so Sam began to study some cool pillows, which can make his wife enjoy the night more comfortably .
Sam designed a cool pillow, which is a combination of soft fiber fabric on one side and cool fabric on the other side. Such pillows not only solve her wife's sleep problem, but also set a new standard for the crushed sponge cool pillow industry.
