Prayer Pillow

• Clinically Proven Neck Pain Relief: A Johns Hopkins University study showed that water pillows significantly reduced morning pain intensity and improved overall sleep quality.
• Fully Adjustable: Users can fill the pillow with varying amounts of tap water (typically 2-5 liters) to achieve their desired level of firmness.
• Dynamic Support: Unlike memory foam that may feel too stiff or down pillows that flatten, the water layer adapts to your head and neck movements instantly as you change positions.
• Versatile for Sleep Positions: Suitable for side, back, and stomach sleepers because the height can be adjusted.
• Cooling Properties: The water inside can provide a cooling sensation, and many models feature breathable, ventilated memory foam or fiber layers on top.
• Components: Usually consists of a sealed, leak-proof water pouch (Waterbase™ technology) at the bottom and a top layer of fiberfill or memory foam for comfort. 

• Filling: A funnel is provided to fill the water bladder, usually with ordinary tap water.
• Removing Air: To avoid a "sloshing" sound, it is crucial to remove all air from the bladder before sealing it.
• Maintenance: It is recommended to change the water every 6-12 months to prevent algae buildup, particularly if using well water.
• Weight: When filled to a firm level, these pillows can be quite heavy (often around 10+ lbs).
