These duck feather and down pillows combine a pure cotton casing with a feather and down filling to provide your head and neck with a medium level of support. They are ideal for those who sleep on their sides and require a denser pillow (or pillows if you have wide shoulders) as they keep your head supported in line with your spine. They may also be used as a supportive bottom pillow when combined with a softer top pillow. Available in standard bed pillow or continental pillow sizes.
