The pillows in this Slumberdown Super Support Pillow 4 Pack have been developed with a unique core block in their centre which holds your head at just the right position for optimum support ideal if you sleep on your side. Side sleepers should use a firm support pillow to ensure they benefit from the correct alignment of the head, neck and spine which in turn encourages the spine to straighten, helping to reduce everyday aches and pains associated with a pillow thats not firm enough for side sleeping. The internal foam core is complemented by a wonderfully supportive hollowfibre filling for a sleep thats comfortable as well as healthy, and the soft touch microfibre cover feels smooth and cosy to sink your head into providing all you need for a great nights sleep.
