The mattress was tested for any possible powder inhalation when using the mattress, and the powder coating is, indeed, safe. The independent lab studies found that the amount of powder coating in the air that could possibly be breathed in is so minuscule, it is within the standards for classifying cleanroom levels and well within what the EPA has determined to be safe for sensitive people, such as those having asthma. That’s safer than the average dust you breathe in all day at home or in the office. Rest easy knowing that your mattress, and the brand you trust, is comfortably safe, and safely comfortable.
