Our memory foam pillow is Certi-Pur-us certified, which means it has been tested to meet Certi Pur-us rigorous standards for emissions, content, performance, and durability. It's guaranteed to be free of chemicals and toxins you really don't want to sleep with. Royal therapy memory foam pillow is made with 100% rayon from bamboo and is imported. It has a polyester/rayon from the bamboo cover that is cool and makes it a comfortable pillow for sleeping and it's removable and machine-washable. It retains its shape so it will not go flat like traditional pillows and it is also normally squeak-free. Plus! You can take out any unnecessary filling to adjust to your height and softness preference. Memory foam pillow holds the contour of the head and neck, distributing weight evenly, relieving pressure, and helping with neck and back pain.
