Did you ever wonder if there were mattress police?
Did you ever wonder if there were mattress police who mandated that mattress label we all hesitate to remove: “Under Penalty Of Law Do Not Remove”? Actually the story goes back to 1913 when it was discovered some mattress companies were making mattresses with stuffings that came from old mattresses, including those from hospitals. That’s gross! Well, that prompted the Minnesota State legislature to enact code 490 in 1913. Within a few years all the states had passed similar legislation. In 1972, the United States Federal Fabrics Act FF-4-72 became law requiring mattress to pass a cigarette ignition test, and the state and Federal lag tags were combined into one.
