Are chemical fire retardants used on the mattresses?

We do not chemically treat our materials, foams or mattresses for any reason. The Leesa and Sapira mattresses are fully encased in a fire retardant sock made up of a proprietary blend of fibers, each chosen for its balance of comfort and flammability performance. Our proprietary fire barrier is an inherently fire retardant fabric so it does not need or have additional chemical treatments. The barrier works by interrupting the combustion process in the event of a fire to meet the requirements of 16 CFR Part 1633. The fire sock functions to smother and dampen flames by causing a layer of char to form, thus preventing oxygen from feeding the fire and subsequently preventing the flames from reaching the foam and spreading.
