Summary of Significant Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation: The consolidated financial statements include the accounts of all subsidiaries. All intercompany balances and transactions have been eliminated in the consolidation.
Operating Segments	Operating Segments: We sell a portfolio of furniture products and services under three brands: Kimball Office, National Office Furniture, and Kimball Hospitality. We consider each of the three brands to be operating segments which aggregate into one reportable segment. The brands operate within six market verticals, selling to similar types of customers. Our products and services are similar in nature and utilize similar production and distribution processes. Our three brands share similar long-term economic characteristics.
Use of Estimates	Use of Estimates: The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“US GAAP”) requires management to make estimates and assumptions that affect the reported amounts included in the consolidated financial statements and related note disclosures. While efforts are made to assure estimates used are reasonably accurate based on management’s knowledge of current events, actual results could differ from those estimates.
Revenue Recognition	Revenue Recognition: We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable, and collectability is reasonably assured. Delivery is not considered to have occurred until the title and the risk of loss passes to the customer according to the terms of the contract. Title and risk of loss are transferred upon shipment to or receipt at our customers’ locations, or in limited circumstances, as determined by other specific sales terms of the transaction. Shipping and handling fees billed to customers are recorded as sales while the related shipping and handling costs are included in cost of goods sold. We recognize sales net of applicable sales tax. Based on estimated product returns and price concessions, a reserve for returns and allowances is recorded at the time of the sale, resulting in a reduction of revenue.
Cash and Cash Equivalents	Cash and Cash Equivalents: Cash equivalents consist primarily of highly liquid investments with original maturities of three months or less at the time of acquisition. Cash and cash equivalents consist of bank accounts and money market funds. Bank accounts are stated at cost, which approximates fair value, and money market funds are stated at fair value.
Notes Receivable and Trade Accounts Receivable	Notes Receivable and Trade Accounts Receivable: Kimball’s notes receivable and trade accounts receivable are recorded per the terms of the agreement or sale, and accrued interest is recognized when earned. We determine on a case-by-case basis the cessation of accruing interest, the resumption of accruing interest, the method of recording payments received on nonaccrual receivables, and the delinquency status for our limited number of notes receivable. Our policy for estimating the allowance for credit losses on trade accounts receivable and notes receivable includes analysis of such items as aging, credit worthiness, payment history, and historical bad debt experience. Management uses these specific analyses in conjunction with an evaluation of the general economic and market conditions to determine the final allowance for credit losses on the trade accounts receivable and notes receivable. Trade accounts receivable and notes receivable are written off after exhaustive collection efforts occur and the receivable is deemed uncollectible. Our limited amount of notes receivable allows management to monitor the risks, credit quality indicators, collectability, and probability of impairment on an individual basis. Adjustments to the allowance for credit losses are recorded in selling and administrative expenses. Customary terms require payment within 30 days, with terms beyond 30 days being considered extended.
Inventories	Inventories: Inventories are stated at the lower of cost or market value. Cost includes material, labor, and applicable manufacturing overhead. Costs associated with underutilization of capacity are expensed as incurred. The last-in, first-out (“LIFO”) method was used for approximately 93% and 91% of consolidated inventories at June 30, 2016 and June 30, 2015, respectively. The remaining inventories were valued using the first-in, first-out (“FIFO”) method. Inventories are adjusted for excess and obsolete inventory. Evaluation of excess inventory includes such factors as anticipated usage, inventory turnover, inventory levels, and product demand levels. Factors considered when evaluating obsolescence include the age of on-hand inventory and reduction in value due to damage, use as showroom samples, design changes, or cessation of product lines.
Property, Equipment, and Depreciation	Property, Equipment, and Depreciation: Property and equipment are stated at cost less accumulated depreciation. Depreciation is provided over the estimated useful life of the assets using the straight-line method for financial reporting purposes. Leasehold improvements are amortized on a straight-line basis over the shorter of the useful life of the improvement or the term of the lease. Major maintenance activities and improvements are capitalized; other maintenance, repairs, and minor renewals are expensed. Depreciation and expenses for maintenance, repairs and minor renewals are included in both the Cost of Sales line and the Selling and Administrative Expense line of the Consolidated Statements of Income.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets: We perform reviews for impairment of long-lived assets whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. Impairment is recognized when estimated future cash flows expected to result from the use of the asset and its eventual disposition are less than its carrying amount. When an impairment is identified, the carrying amount of the asset is reduced to its estimated fair value. Assets to be disposed of are recorded at the lower of net book value or fair market value less cost to sell at the date management commits to a plan of disposal.
Impairment or Disposal of Intangible Assets	Intangible assets are reviewed for impairment when events or circumstances indicate that the carrying value may not be recoverable over the remaining lives of the assets.
Other Intangible Assets	Internal-use software is stated at cost less accumulated amortization and is amortized using the straight-line method. During the software application development stage, capitalized costs include external consulting costs, cost of software licenses, and internal payroll and payroll-related costs for employees who are directly associated with a software project. Upgrades and enhancements are capitalized if they result in added functionality which enable the software to perform tasks it was previously incapable of performing. Software maintenance, training, data conversion, and business process reengineering costs are expensed in the period in which they are incurred. Product rights to produce and sell certain products are amortized on a straight-line basis over their estimated useful lives. We have no intangible assets with indefinite useful lives which are not subject to amortization.
Research and Development	Research and Development: The costs of research and development are expensed as incurred.
Advertising	Advertising: Advertising costs are expensed as incurred.
Insurance and Self-insurance	Insurance and Self-insurance: We are self-insured for certain employee health benefits including medical, short-term disability, and dental. Our self-insured reserves are estimated based upon a number of factors including known claims, estimated incurred but not reported claims, and other analyses, which are based on historical information along with certain assumptions about future events. Insurance benefits are not provided to retired employees. We also participate, along with other companies, in a group captive insurance company (“Captive”). The Captive insures losses related to workman's compensation, motor vehicle liability, product liability, and general liability. The Captive reinsures catastrophic losses for all participants, including Kimball, in excess of predetermined amounts. We pay premiums to the Captive which accumulate as a prepaid deposit estimated for losses related to the above coverage. We also maintain a reserve for outstanding unpaid workers’ compensation claims, including an estimate of incurred but not reported claims. Additionally, we purchase insurance coverage for property insurance, director and officer liability insurance, umbrella coverage, and other risks.
Income Taxes	Income Taxes: Deferred income taxes are recognized for the estimated future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. The deferred taxes are measured using enacted tax rates expected to apply to taxable income in the years in which the temporary differences are expected to reverse. We evaluate the recoverability of deferred tax assets each quarter by assessing the likelihood of future taxable income and available tax planning strategies that could be implemented to realize our deferred tax assets. If recovery is not likely, we provide a valuation allowance based on our best estimate of future taxable income in the various taxing jurisdictions and the amount of deferred taxes ultimately realizable. Future events could change management’s assessment. We early adopted the Financial Accounting Standards Board (“FASB”) guidance on simplifying the balance sheet classification of deferred taxes, using the retrospective transition method, and thus have classified all deferred tax assets and liabilities as noncurrent in our consolidated balance sheets.
Income Tax Uncertainties	We operate within multiple taxing jurisdictions and are subject to tax audits in these jurisdictions. These audits can involve complex uncertain tax positions, which may require an extended period of time to resolve. A tax benefit from an uncertain tax position may be recognized only if it is more likely than not that the tax position will be sustained on examination by taxing authorities, based on the technical merits of the position. We maintain a liability for uncertain income tax and other tax positions, including accrued interest and penalties on those positions. As tax positions are effectively settled, the tax liability is adjusted accordingly. We recognize interest and penalties related to unrecognized tax benefits in the Provision (Benefit) for Income Taxes line of the Consolidated Statements of Income.
Concentrations of Credit Risk	Concentrations of Credit Risk: Certain business and credit risks are inherent in our business. Additionally, we currently have a note receivable related to the sale of an Indiana facility, a note receivable from a dealer, and other miscellaneous notes receivable which are included on the Receivables and Other Assets lines of the Consolidated Balance Sheets.
Off-Balance-Sheet Risk	Off-Balance Sheet Risk: Our off-balance sheet arrangements are limited to standby letters of credit, a performance bond, and operating leases entered into in the normal course of business as described in Note 5 - Commitments and Contingent Liabilities of Notes to Consolidated Financial Statements.
Non-operating Income and Expense	Non-operating Income and Expense: Non-operating income and expense include the impact of such items as fair value adjustments on Supplemental Employee Retirement Plan (“SERP”) investments, foreign currency rate movements, bank charges, investment gain or loss, non-production rent income, and other miscellaneous non-operating income and expense items that are not directly related to operations. The gain or loss on SERP investments is offset by a change in the SERP liability that is recognized in selling and administrative expenses.
Foreign Currency Translation	Foreign Currency Translation: Kimball's continuing foreign operation, a non-manufacturing office in China, uses the U.S. Dollar as its functional currency. Foreign currency assets and liabilities are remeasured into functional currencies at end-of-period exchange rates, except for nonmonetary assets and equity, which are remeasured at historical exchange rates. Revenue and expenses are remeasured at the weighted average exchange rate during the fiscal year, except for expenses related to nonmonetary assets, which are remeasured at historical exchange rates. Gains and losses from foreign currency remeasurement are reported in the Non-operating income or expense line item on the Consolidated Statements of Income. Gains and losses from foreign currency remeasurement into EUR and USD functional currencies related to our former EMS segment are included in the Income from Discontinued Operations, Net of Tax line item of the Consolidated Statements of Income.
Derivative Instruments and Hedging Activities	During fiscal years 2015 and 2014, prior to the spin-off of our EMS segment, derivative instruments were utilized to hedge the exposure to foreign currency exchange rate fluctuations. See Note 12 - Derivative Instruments of Notes to Consolidated Financial Statements for more information on derivative instruments and hedging activities.
Stock-Based Compensation	Stock-Based Compensation: As described in Note 8 - Stock Compensation Plans of Notes to Consolidated Financial Statements, Kimball maintains a stock-based compensation plan which allows for the issuance of restricted stock, restricted share units, unrestricted share grants, incentive stock options, nonqualified stock options, performance shares, performance units, and stock appreciation rights for grant to officers and other key employees and to members of the Board of Directors who are not employees. We recognize the cost resulting from share-based payment transactions using a fair-value-based method. The estimated fair value of outstanding performance shares and restricted share units is based on the stock price at the date of the grant. For performance shares, the price is reduced by the present value of dividends normally paid over the vesting period which are not payable on outstanding performance share awards. The estimated fair value of outstanding relative total shareholder return performance units (“RTSR”) is based on the grant date fair value of RTSR awards using a Monte Carlo simulation which includes estimating the movement of stock prices and the effects of volatility, interest rates, and dividends. Stock-based compensation expense is recognized for the portion of the awards that are ultimately expected to vest. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.
Recent Accounting Pronouncements	Recent Accounting Pronouncements: In June 2016, the FASB issued guidance on the measurement of credit losses on financial instruments. Under the guidance, an entity recognizes as an allowance its estimate of expected credit losses, which the FASB believes will result in more timely recognition of such losses. The guidance is also intended to reduce the complexity by decreasing the number of credit impairment models that entities use to account for debt instruments. The guidance is effective for our first quarter of fiscal year 2021 with early adoption in our fiscal year 2020 permitted. We have not yet determined the effect of this guidance on our consolidated financial statements. In March 2016, the FASB issued guidance on simplifying the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as the classification on the statement of cash flows. The guidance is effective for our first quarter of fiscal year 2018 with early adoption permitted. We have not yet selected a transition method nor determined the effect of this guidance on our consolidated financial statements. In February 2016, the FASB issued guidance that revises the accounting for leases. The guidance is intended to improve financial reporting of leasing transactions by requiring lessees to record right-of-use assets and corresponding lease liabilities on the balance sheet. Leases will continue to be classified as either operating or finance leases, with the classification affecting the pattern of expense recognition in the statement of income. The guidance will also require additional disclosures to help investors and other financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases. The guidance is effective for our first quarter of fiscal year 2020 with early adoption permitted, and is required to be applied using a modified retrospective approach to each prior reporting period. We have not yet determined the effect of this guidance on our consolidated financial statements. In January 2016, the FASB issued guidance which is intended to improve the recognition and measurement of financial instruments. The guidance revises an entity’s accounting related to the classification and measurement of investments in equity securities and the presentation of certain fair value changes for financial liabilities measured at fair value. The guidance also amends certain disclosure requirements associated with the fair value of financial instruments. The guidance is effective prospectively for our first quarter of fiscal year 2019 financial statements with early adoption allowed on certain provisions. We have not yet selected a transition method nor determined the effect of this guidance on our consolidated financial statements. In November 2015, the FASB issued guidance on simplifying the balance sheet classification of deferred taxes. The guidance requires the classification of deferred tax assets and liabilities as noncurrent in a classified balance sheet. The current requirement that deferred tax assets and liabilities of a tax-paying component of an entity be offset and presented as a single amount is not affected by this update. The guidance is effective for our first quarter of fiscal year 2018 financial statements with early adoption permitted, and allows for the use of either a prospective or retrospective transition method. We have early adopted using the retrospective transition method for our fiscal year ending June 30, 2016, and thus have reclassified current deferred tax assets and liabilities to noncurrent in our consolidated balance sheet. As a result for June 30, 2015, $12.3 million of current deferred tax assets that were included in prepaid expenses and other current assets and $0.9 million of deferred tax liabilities that were included in other long term liabilities have been reclassified to noncurrent deferred tax assets in the consolidated balance sheet. In July 2015, the FASB issued guidance on simplifying the measurement of inventory which applies to inventory that is measured using first-in, first-out (“FIFO”) or average cost. Inventory within the scope of this update is required to be measured at the lower of cost or net realizable value, which is the estimated selling price in the ordinary course of business less reasonably predictable costs of completion, disposal, and transportation. The guidance does not impact inventory measured on a last-in, first-out (“LIFO”) basis. The standards update is effective prospectively for our first quarter fiscal year 2018 financial statements with early adoption permitted. We do not expect the adoption to have a material effect on our consolidated financial statements. In April 2015, the FASB issued guidance that requires debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability and further clarification guidance allows the cost of securing a revolving line of credit to be recorded as a deferred asset regardless of whether a balance is outstanding. This guidance is effective for our first quarter fiscal year 2017 financial statements. We currently comply with this method therefore the adoption will not have a material effect on our consolidated financial statements. In April 2015, the FASB issued guidance on customer’s accounting for cloud computing fees and provided criteria for customers in a cloud computing arrangement to use to determine whether the arrangement includes a license of software. The guidance clarifies that a software license included in a cloud computing arrangement should be accounted for consistent with the acquisition of other software licenses, whereas a cloud computing arrangement that does not include a software license should be accounted for as a service contract. The guidance is effective for our first quarter of fiscal year 2017 financial statements, and allows for the use of either a prospective or retrospective transition method. We plan to adopt using the prospective transition method for our first quarter of fiscal year 2017, and we do not expect the adoption to have a material effect on our consolidated financial statements. In June 2014, the FASB provided explicit guidance on how to account for share-based payments granted to employees in which the terms of the award provide that a performance target that affects vesting could be achieved after the requisite service period. The guidance will be applied prospectively for our first quarter fiscal year 2017 financial statements. We do not expect the adoption to have a material effect on our consolidated financial statements. In May 2014, the FASB issued guidance on the recognition of revenue from contracts with customers. The core principle of the guidance is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration which the company expects to receive in exchange for those goods or services. To achieve this core principle, the guidance provides a five-step analysis of transactions to determine when and how revenue is recognized. The guidance addresses several areas including transfer of control, contracts with multiple performance obligations, and costs to obtain and fulfill contracts. The guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. In July 2015, the FASB decided to defer the effective date for this new revenue standard by one year, which will make the guidance effective for our first quarter fiscal year 2019 financial statements using either of two acceptable adoption methods: (i) retrospective adoption to each prior reporting period presented with the option to elect certain practical expedients; or (ii) adoption with the cumulative effect of initially applying the guidance recognized at the date of initial application and providing certain additional disclosures. In March 2016, the FASB issued additional guidance which further clarifies assessing whether an entity is a principal or an agent in a revenue transaction, and impacts whether an entity reports revenue on a gross or net basis; in April 2016, the FASB issued additional guidance that addresses identifying performance obligations and implementing licensing guidance; and in May 2016, the FASB issued additional guidance that clarifies collectability, noncash consideration, and other transition issues. The amendments have the same effective date and transition requirements as the new revenue standard. We have not yet selected a transition method nor determined the effect of this guidance on our consolidated financial statements. In April 2014, the FASB issued guidance on reporting discontinued operations and disclosures of disposals of components of an entity. Under the new guidance, a disposal that represents a strategic shift that has or will have a major effect on an entity’s operations and financial results is a discontinued operation. The new guidance requires expanded disclosures that will provide more information about the assets, liabilities, income, and expenses of discontinued operations, and also requires disclosures of significant disposals that do not qualify for discontinued operations reporting. The guidance was effective prospectively for disposals or components of our business classified as held for sale beginning in our first quarter of fiscal year 2016. The adoption did not have a material effect on our consolidated financial statements.
