Side-sleeping on an ordinary pillow can cause your head to tilt forward, placing pressure on your neck, shoulder and spine. Not to mention squashing your ear. This pillow has deeply padded, 16.5cm 'wings to cradle your head and neck. Plus, a central depression that protects your ear, and a recess at the base preventing your shoulder bending and your arm going to sleep. The pillow is filled with lightweight, soft, shape-retaining '3D fibres to stop it flattening.
