How you stack your pillows for sleeping will depend on their loft and your sleep position. 'A side sleeper pillow or pillows should total 4 to 6 inches for the proper head, neck, and spinal alignment,' explains Stephen Light. 'Stomach and back sleepers won’t need to stack pillows for neck support and comfort, and can sleep on one pillow'.
Sleeping on one standard pillow, plush enough, is the most common. Peri Lauren says 'I always have one standard standing up and then I sleep on one standard. This stops my head from touching the headboard or wall.'
