The only pillow that is proven to reduce neck pain and improve your sleep quality. The Water PillowTM has a Waterbase TechnologyTM, a water pouch built into the pillow, so you can personalise your comfort by adding water, the fuller the waterbase, the firmer the pillow becomes.  The water moves as you move responding to your sleeping position and any movement you make, always offering consistent support as you sleep. This prevents you from waking up throughout the night, helping to aid a deeper, more restful sleep. The pillow\'s creator suffered with neck pain after a car accident left him with whip lash. After working with scientists and researchers he invented the Water Pillow, now the pillow is recommended by 10,000s of health care professionals to provide better sleep for neck pain sufferers. The waterbase is surrounded by a thermal insulator which keeps the water at body temperature, so there is no need to worry about the pillow feeling too hot or cold. A deep layer of soft fibre rests over the waterbase for complete comfort. The pillow is covered in a luxurious cotton cover that is smooth, soft and breathable. Comes complete with a funnel along with filling and care instructions.
