Our shredded memory foam pillow is encased in a high quality vented weave fabric made from a special blend of all-natural high grade cotton which is machine washable. The memory foam filling is specially engineered and designed to never go flat and will retain its shape over its life span. Studies have shown that many people have poor sleep cycles and are sleeping less than six hours a night. Chronic sleep problems not only make people less attentive and focused, but can also lead to health problems such as high blood pressure and headaches. We urge our customers to invest in their overall health by trying our shredded memory foam pillow.
