The Slumberdown Super Cool 4 pack has been developed with a moisture wicking soft touch microfibre cover and has been filled with bounce back supportive hollowfibre, making it the ideal pillow for side sleepers during the warmer summer months. 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 that’s not firm enough for side sleeping. Enjoy a supported sleep that's comfortable and heathy. Slumberdown
