Basis of Presentation [Abstract]
Business Description and Basis of Presentation	Basis of PresentationThe accompanying unaudited Condensed Consolidated Financial Statements of Kimball International, Inc. (the “Company,” “Kimball International,” “we,” “us,” or “our”) have been prepared in accordance with the instructions to Form 10-Q. As such, certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted, although we believe that the disclosures are adequate to make the information presented not misleading. Intercompany transactions and balances have been eliminated. Management believes the financial statements include all adjustments (consisting only of normal recurring adjustments) considered necessary to present fairly the financial statements for the interim periods. The results of operations for the interim periods shown in this report are not necessarily indicative of results for any future interim period or for the entire fiscal year. It is suggested that these financial statements be read in conjunction with the financial statements and the notes thereto included in our latest annual report on Form 10-K. Additionally, based on the duration and severity of the current global situation involving the COVID-19 pandemic, including but not limited to the prolonged reduction in travel and the speed of the recovery of economic conditions globally, the extent to which COVID-19 will impact our business and our consolidated financial results will depend on future developments, which are highly uncertain and cannot be predicted.
