Whether or not the Casper mattresses contains fiberglass depends on your location. Previously, Casper mattresses contained filament fiberglass as a fire barrier. As of 2024, the fire barrier has been updated to use a Rayon fiber-based product.
However, regulations in Canada allow different materials to be used in the fire barrier of a mattress. Therefore, those mattresses may still contain fiberglass.
