So far, we know that the pillow is one of the bedroom equipment that functions as a headboard. Launching from Wikipedia, the pillow is a head support that we use to sleep on the bed, and also functions as a support for the body when we sit on a sofa or chair.
Apparently, not only as a head support while sleeping, there are other types of pillow models that we can use everyday. For example, a neck pillow that can be used when traveling. In addition, there are also mini contour pillows that can help with health problems.
