Rejuvenite Pillows are the most pressure relieving, breathable and supportive pillows on the market. They are manufactured with a “live cell structure” which provides endless support and keeps the shape of the pillow over time. Conventional pillows, while fluffy when they are new, can flatten over time. This causes neck pain in the morning. While your sleeping on your Rejuvenite pillow, it is constantly working to help you sleep and more importantly, stay asleep.
