The Pillow Cube is the most comfortable and OBVIOUS pillow for side sleepers on the market. Yeah, it’s obvious, your head and shoulder make a square, so the ideal pillow for sleeping on your side should be a cube.
The Pillow Cube comes in two different sizes: 5 inches, and 6 inches. People with broad shoulders and big noggins will LOVE the 6 inch Pillow Cube, while people with narrower shoulders will prefer the 5 inch Pillow Cube.
