To keep costs down, we manufacture our pillows in one size only. The (soft) CNH Pillow is very soft and very thin: just 3 inches. If you prefer a thin pillow, or no pillow, use just the CNH Pillow. If you prefer a thicker pillow, you can place the CNH Pillow on top of any number or size of additional pillows you wish. We believe the SleepEasy CNH Pillow, when used with our customers' other pillows, thick or thin, can suit anyone's comfort preferences.
