Companies that have verified they use CertiPUR-US-certified flexible polyurethane foam in their products may use our seal, but are not required to label their products or packaging. Lack of our seal is not an indication the flexible polyurethane foam inside is not certified. You can look up the companies on our website to be sure they are participating in our program. If you feel a company is misrepresenting CertiPUR-US certification, please visit certipur.us/report-misuse/. If you can include detailed information with a photo, website link, and a contact name, that will help our investigation.
