We recently made updates to our inversion table owner's manuals and user instructions. If you have purchased one of the inversion tables, you have received a letter that summarizes the changes. You can download your updated owner's manuals here for inversion tables with model numbers containing 55-1527, 55-1528, 55-1529, 55-1530, 55-1532, 55-1535, 55-1538, and 55-1539. When you download your new manual, we will ask for your mailing address so we can send your new warning label as described in the owner's manual. Your contact information will only be used for this purpose or to contact you regarding this update. It will not be used in any other way. If you have questions, please contact us at 1-800-375-7520.
