If you’re a back sleeper, the SNUZ Pillow’s unique, hourglass design perfectly fits, cradles and supports the curve of your neck and the back of your head… If you’re a side sleeper, the SNUZ Pillow provides ideal head support & neck and spinal alignment. And the gentle dip in the middle of the pillow prevents pressure on your ear created by the crown of regular pillows… If you’re a stomach sleeper, the cavity on the bottom creates the perfect channel for your arm, while still offering neck and spinal alignment and reduced pressure on your ear.
