The fire retardant layer in your mattress is essential to keeping you safe in the event of an emergency but common FR layers often rely on plastics or fiberglass materials to provide protection.
Instead, the Birch mattresses use a combination of organic wool fibers and natural rayon to provide the protection you need without exposure to harmful chemicals. The rayon used in our natural and organic mattresses is a natural fiber that is created from purified cellulose and is harvested primarily from wood pulp.
The ¼ inch FR layer in all of our Birch mattresses is placed directly below the mattress cover to ensure your safety, and is also built into the bottom layer to provide protection throughout the Birch Natural Mattress and Birch Luxe Natural Mattress.
