Our mattress protectors are made of the natural organic cotton jersey on the sleeping surface and waterproof polyurethane. The polyurethane backing is inert and does not emit harmful chemicals to the body. Elastic around the edges so that it fits over your mattress like a fitted sheet. Twin & Full fit mattresses that are up to 14" thick. Extra Long Twin, Queen, King, and Cal King fit mattresses up to 18" thick.
The polyurethane is non-toxic. It does not off-gas. It is inert until it reaches 450 degrees. In other words, it would not change chemistry until the temperature reaches at least 450 degrees. It is also biodegradable. Protects against dust mites and perfect for most people with sensitive skin or allergies.
Care: Machine washes in warm with similar colors. Dry on low or air dry. Remove promptly for best results. Made in the USA from fabric imported from Canada.
