Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis Of Presentation	Basis of Presentation The condensed consolidated financial statements have been prepared by Herman Miller, Inc. (“the company”) in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. Management believes the disclosures made in this document are adequate with respect to interim reporting requirements. The accompanying unaudited condensed consolidated financial statements, taken as a whole, contain all adjustments that are of a normal recurring nature necessary to present fairly the financial position of the company as of March 3, 2018 . Operating results for the three and nine months ended months ended March 3, 2018 , are not necessarily indicative of the results that may be expected for the year ending June 2, 2018 . It is suggested that these condensed consolidated financial statements be read in conjunction with the financial statements and notes thereto included in the company's annual report on Form 10-K for the year ended June 3, 2017 . The company's fiscal year ends on the Saturday closest to May 31. Fiscal 2018 , the year ending June 2, 2018 , and fiscal 2017 , the year ended June 3, 2017 , contain 52 and 53 weeks, respectively. The nine months ended March 3, 2018 and March 4, 2017 contained 39 and 40 weeks, respectively. The three months ended March 3, 2018 and March 4, 2017

Accounting Policies [Abstract]
Recently Issued Accounting Standards	Recently Issued Accounting Standards Recently Adopted Accounting Standards Standard Description Effective Date Effect on the Financial Statements or Other Significant Matters Improvements to Employee Share-Based Payment Accounting Under the new guidance, all excess tax benefits/deficiencies should be recognized as income tax expense/benefit, entities may elect how to account for forfeitures and cash paid by an employer when directly withholding shares for tax withholding purposes should be classified as a financing activity on the cash flow statement. June 4, 2017 The company adopted the accounting standard in the first quarter of fiscal 2018. As a result, the company elected to change its policy from estimating forfeitures to recognizing forfeitures when they occur, which resulted in an increase in Retained earnings of $0.1 million, a decrease in Additional paid in capital of $0.3 million and an increase in Other noncurrent assets of $0.2 million in the Condensed Consolidated Balance Sheets. The other impacts resulting from adoption did not have a material impact on the company's Financial Statements. Recently Issued Accounting Standards Not Yet Adopted Standard Description Effective Date Effect on the Financial Statements or Other Significant Matters Revenue from Contracts with Customers The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard is designed to create greater comparability for financial statement users across industries and jurisdictions and also requires enhanced disclosures. The standard allows for two adoption methods, a full retrospective or modified retrospective approach. June 3, 2018 The company has completed a preliminary review of the impact of the new standard and expects changes in the identification of performance obligations around product and service revenue. For commercial contracts in which the company sells directly to end customers, in most cases, the company currently delays revenue recognition until the products are shipped and installed and records third-party installation and certain other fees net. However, under the new standard, in most cases, the company will recognize product revenue when title and risk of loss have transferred and will recognize service revenue upon the completion of services. Additionally, the company will record certain product pricing elements related to its direct customer sales within revenue and Cost of Sales rather than net within revenue as is current practice. The company has determined that these elements relate to the product performance obligation which the company is considered to control under the new standard. The company is also in the process of implementing changes to its business processes, systems and controls to support recognition and disclosure under the new standard. The company expects to adopt the standard in fiscal 2019 using the modified retrospective approach. Standard Description Effective Date Effect on the Financial Statements or Other Significant Matters Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities The standard provides guidance for the measurement, presentation and disclosure of financial assets and liabilities. The standard requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and recognize any change in fair value in net income. The standard does not permit early adoption and at adoption a cumulative-effect adjustment to beginning retained earnings should be recorded. June 3, 2018 The company is currently evaluating the impact of adopting this guidance. Compensation - Retirement Benefits: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost This standard changes the rules related to the income statement presentation of the components of net periodic benefit cost for defined benefit pension and other postretirement benefit plans. Under the new guidance, entities must present the service cost component of net periodic benefit cost in the same income statement line items as other employee compensation costs related to services rendered during the period. Other components of net periodic benefit cost will be presented separately from the line items that include the service cost. Early adoption is permitted. June 3, 2018 The standard is expected to impact the classification of certain costs within the company's Consolidated Statements of Comprehensive Income. No impact to the company's Consolidated Balance Sheets or Consolidated Statements of Cash Flow are expected as a result of the standard. Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income This update allows for the reclassification to retained earnings of the tax effects stranded in Accumulated Other Comprehensive Income resulting from The Tax Cuts and Jobs Act. Early adoption is permitted. June 2, 2019 The company is still evaluating these amendments and has not determined its accounting policy and whether or not an election will be made to reclassify the stranded effects. Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities This update amends the hedge accounting recognition and presentation with the objectives of improving the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities and simplifying the application of hedge accounting. The update expands the strategies eligible for hedge accounting, relaxes the timing requirements of hedge documentation and effectiveness assessments and permits the use of qualitative assessments on an ongoing basis to assess hedge effectiveness. The new guidance also requires new disclosures and presentation. June 2, 2019 The company is currently evaluating the impact of adopting this guidance. Leases Under the updated standard a lessee's rights and obligations under most leases, including existing and new arrangements, would be recognized as assets and liabilities, respectively, on the balance sheet. The standard must be adopted under a modified retrospective approach and early adoption is permitted. June 2, 2019 The standard is expected to have a significant impact on our Consolidated Financial Statements; however, the company is currently evaluating the impact.

Acquisitions	Acquisitions and Divestitures Contract Furniture Dealerships On July 31, 2017, the company completed the sale of a wholly-owned contract furniture dealership in Vancouver, Canada for initial cash consideration of $2.0 million . A pre-tax gain of $1.1 million was recognized as a result of the sale within the caption Selling, general and administrative within the Condensed Consolidated Statements of Comprehensive Income. On January 1, 2017, the company completed the sale of a wholly-owned contract furniture dealership in Philadelphia, Pennsylvania in exchange for $3.0 million , that was comprised of both a term note receivable and a line of credit. A pre-tax gain of $0.7 million was recognized as a result of the sale within the caption Selling, general and administrative within the Condensed Consolidated Statements of Comprehensive Income. These long-term receivables were deemed to be variable interests in a variable interest entity. The carrying value of the long-term receivables was $2.3 million and $1.4 million as of March 3, 2018 and June 3, 2017 , respectively, and represents the company's maximum exposure to loss. The company is not deemed to be the primary beneficiary of the variable interest entity as the buyers of the dealership control the activities that most significantly impact the entity's economic performance, including sales, marketing and operations. Naughtone Holdings Limited On June 3, 2016, the company acquired a 50 percent noncontrolling equity interest in Naughtone Holdings Limited ("Naughtone"), a leader in soft seating products, stools, occasional and meeting tables, for $12.4 million in cash consideration.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The company recognizes interest and penalties related to uncertain tax benefits through income tax expense in its Condensed Consolidated Statement of Comprehensive Income. Interest and penalties recognized in the company's Condensed Consolidated Statement of Comprehensive Income were negligible for the three and nine months ended March 3, 2018 and March 4, 2017 . The company's recorded liability for potential interest and penalties related to uncertain tax benefits was: (In millions) March 3, 2018 June 3, 2017 Liability for interest and penalties $ 1.0 $ 0.8 Liability for uncertain tax positions, current 3.0 2.8 O n December 22, 2017, the Tax Cuts and Jobs Act (the “Act”) was signed into law in the United States. In accordance with Securities and Exchange Commission Staff Accounting Bulletin No. 118, the results of operations for the three-month period ended March 3, 2018 included the provisional amounts of the effect of the reduction of the federal corporate income tax rate as well as the effect of the new participation exemption system of taxation on foreign earnings, among other provisions. Effective January 1, 2018 the federal income tax rate was reduced from 35 percent to 21 percent . For fiscal tax payers a full year federal income tax rate is calculated based upon the number of days in the year subject to the 35 percent and the 21 percent tax rates. As a result, the company’s statutory federal tax rate for the fiscal year ending June 2, 2018 is 29.1 percent . The three-month and nine-month periods ended March 3, 2018 include a provisional, discrete amount of $3 million in reduced income tax expense resulting from the reduced federal income tax rate. Also, a provisional, discrete favorable impact totaling $8.7 million was triggered as a result of applying the lower federal income tax rates to the company’s net deferred tax liabilities. As part of the transition towards the participation exemption system, in the three-month period ended March 3, 2018, the company recorded a provisional discrete U.S. tax liability of $9.2 million on certain undistributed foreign earnings. The one-time tax is based in part on the amount of earnings held in cash and other specified assets as of June 2, 2018. No other provision was made for income taxes that may result from future remittances of the undistributed earnings of foreign subsidiaries as these amounts continue to be indefinitely reinvested in foreign operations and determining the amount of unrecognized deferred tax liability is not practicable. The company will continue to refine its calculations as additional analysis is completed and these changes could be material to the consolidated financial statements. For tax years beginning after December 31, 2017, the Act subjects a U.S. shareholder to tax on global intangible low-taxed income (“GILTI”) earned by certain foreign subsidiaries. The FASB Staff Q&A, Topic 740, No. 5, Accounting for Global Intangible Low-Taxed Income , states that an entity can make an accounting policy election to either recognize deferred taxes for temporary basis differences expected to reverse as GILTI in future years or provide for the tax expense related to GILTI in the year the tax is incurred. The company is still evaluating the effects of the GILTI provisions and has not yet determined its accounting policy. In determining the provision for income taxes for the three-month period ended March 3, 2018, the company used an estimated annual effective tax rate which was based on expected annual income and statutory tax rates across the various jurisdictions in which it operates, which included effects of the Act. The effective tax rates were 19.0 percent and 29.8 percent , respectively, for the three-month periods ended March 3, 2018 and March 4, 2017. The effective tax rates were 27.3 percent and 31.5 percent , respectively, for the nine-month periods ended March 3, 2018 and March 4, 2017. The year over year decrease in the effective tax rate for the three and nine-month periods ended March 3, 2018 was the result of the Act and an increase in the mix of earnings in tax jurisdictions that had rates that were lower than the United States federal statutory rate. The effective tax rates for the three and nine-month periods ended March 3, 2018 and March 4, 2017 are lower than the United States federal statutory rate due to the mix of earnings in taxing jurisdictions that had rates that were lower than the United States federal statutory rate, along with the manufacturing deduction under the American Jobs Creation Act of 2004 (“AJCA”) and the research and development tax credit under the Protecting Americans from Tax Hikes ("PATH") Act of 2015. The company is subject to periodic audits by domestic and foreign tax authorities. Currently, the company is undergoing routine periodic audits in both domestic and foreign tax jurisdictions. It is reasonably possible that the amounts of unrecognized tax benefits could change in the next twelve months as a result of the audits. Tax payments related to these audits, if any, are not expected to be material to the company's Condensed Consolidated Statements of Comprehensive Income.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The company's financial instruments consist of cash equivalents, marketable securities, accounts and notes receivable, deferred compensation plan, accounts payable, debt, redeemable noncontrolling interests, interest rate swaps and foreign currency exchange contracts. The company's financial instruments, other than long-term debt, are recorded at fair value. The carrying value and fair value of the company's long-term debt, including current maturities, is as follows for the periods indicated: (In millions) March 3, 2018 June 3, 2017 Carrying value $ 278.3 $ 203.1 Fair value $ 281.9 $ 213.0 The following describes the methods the company uses to estimate the fair value of financial assets and liabilities, which have not significantly changed in the current period: Cash and cash equivalents — The company invests excess cash in short term investments in the form of commercial paper and money market funds. Commercial paper is valued at amortized costs while money market funds are valued using net asset value. Available-for-sale securities — The company's available-for-sale marketable securities primarily include equity and fixed income mutual funds and government obligations. These investments are recorded at fair value using quoted prices for similar securities. Foreign currency exchange contracts — The company's foreign currency exchange contracts are valued using an approach based on foreign currency exchange rates obtained from active markets. The estimated fair value of forward currency exchange contracts is based on month-end spot rates as adjusted by market-based current activity. These forward contracts are not designated as hedging instruments. Interest rate swap agreements — The value of the company's interest rate swap agreements is determined using a market approach based on rates obtained from active markets. The interest rate swap agreements are designated as cash flow hedging instruments. Deferred compensation plan — The company's deferred compensation plan primarily includes various domestic and international mutual funds that are recorded at fair value using quoted prices for similar securities. Other — The company's contingent consideration liabilities and redeemable noncontrolling interests are deemed to be a nonrecurring level 3 fair value measurement. Refer to Note 14 for further information regarding redeemable noncontrolling interests. The following tables set forth financial assets and liabilities measured at fair value in the Condensed Consolidated Balance Sheets and the respective pricing levels to which the fair value measurements are classified within the fair value hierarchy as of March 3, 2018 and June 3, 2017 . (In millions) March 3, 2018 June 3, 2017 Financial Assets Quoted Prices with Other Observable Inputs (Level 2) Management Estimate (Level 3) Quoted Prices with Management Estimate (Level 3) Cash and cash equivalents: Money market funds $ 31.4 $ — $ — $ — Commercial paper 70.0 — — — Available-for-sale marketable securities: Mutual funds - fixed income 7.6 — 7.7 — Mutual funds - equity 0.8 — 0.9 — Foreign currency forward contracts 0.5 — 0.5 — Interest rate swap agreement 13.7 — 3.3 — Deferred compensation plan 11.7 — 12.8 — Total $ 135.7 $ — $ 25.2 $ — Financial Liabilities Foreign currency forward contracts $ 0.6 $ — $ 0.6 $ — Contingent consideration — 0.4 — 0.5 Total $ 0.6 $ 0.4 $ 0.6 $ 0.5 The table below presents a reconciliation for liabilities measured at fair value using significant unobservable inputs (Level 3) (in millions). Contingent Consideration March 3, 2018 June 3, 2017 Beginning balance $ 0.5 $ 2.7 Net realized losses (gains) — (0.2 ) Payments (0.1 ) (2.0 ) Ending balance $ 0.4 $ 0.5 The contingent consideration liabilities represent future payment obligations that relate to business and product line acquisitions. These payments are based on the future performance of the acquired businesses or product line. The contingent consideration liabilities are valued using estimates based on discount rates that reflect the risk involved and the projected sales and earnings of the acquired businesses. The estimates are updated and the liabilities are adjusted to fair value on a quarterly basis. The following is a summary of the carrying and market values of the company's marketable securities as of the respective dates: March 3, 2018 June 3, 2017 (In millions) Cost Unrealized Gain/(loss) Market Value Cost Unrealized Market Mutual funds - fixed income $ 7.6 $ — $ 7.6 $ 7.6 $ 0.1 $ 7.7 Mutual funds - equity 0.7 0.1 0.8 0.9 — 0.9 Total $ 8.3 $ 0.1 $ 8.4 $ 8.5 $ 0.1 $ 8.6 Adjustments to the fair value of available-for-sale securities are recorded as increases or decreases, net of income taxes, within Accumulated other comprehensive loss in stockholders’ equity. These adjustments are also included within the caption Unrealized holding gain within the Condensed Consolidated Statements of Comprehensive Income. Unrealized gains recognized in the company's Condensed Consolidated Statement of Comprehensive Income related to available-for-sale securities were nominal for the three and nine month periods ended March 3, 2018 and March 4, 2017 . The cost of securities sold is based on the specific identification method; realized gains and losses resulting from such sales are included in the Condensed Consolidated Statements of Comprehensive Income within "Other, net". The company reviews its investment portfolio for any unrealized losses that would be deemed other-than-temporary and require the recognition of an impairment loss in earnings. If the cost of an investment exceeds its fair value, the company evaluates, among other factors, general market conditions, the duration and extent to which the fair value is less than its cost, the company's intent to hold the investment, and whether it is more likely than not that the company will be required to sell the investment before recovery of the cost basis. The company also considers the type of security, related industry and sector performance, and published investment ratings. Once a decline in fair value is determined to be other-than-temporary, an impairment charge is recorded and a new cost basis in the investment is established. If conditions within individual markets, industry segments, or macro-economic environments deteriorate, the company could incur future impairments. The company views its available-for-sale portfolio as available for use in its current operations. Accordingly, the investments are recorded within Current Assets within the Condensed Consolidated Balance Sheets. Derivative Instruments and Hedging Activities Foreign Currency Forward Contracts The company transacts business in various foreign currencies and has established a program that primarily utilizes foreign currency forward contracts to reduce the risks associated with the effects of certain foreign currency exposures. Under this program, the company's strategy is to have increases or decreases in our foreign currency exposures offset by gains or losses on the foreign currency forward contracts to mitigate the risks and volatility associated with foreign currency transaction gains or losses. Foreign currency exposures typically arise from net liability or asset exposures in non-functional currencies on the balance sheets of our foreign subsidiaries. Foreign currency forward contracts generally settle within 30 days and are not used for trading purposes. These forward contracts are not designated as hedging instruments. Accordingly, we record the fair value of these contracts as of the end of the reporting period in the Consolidated Balance Sheets with changes in fair value recorded within the Consolidated Statements of Comprehensive Income. The balance sheet classification for the fair values of these forward contracts is to Other current assets for unrealized gains and to Other accrued liabilities for unrealized losses. The Consolidated Statements of Comprehensive Income classification for the fair values of these forward contracts is to Other expenses (income): Other, net, for both realized and unrealized gains and losses. Interest Rate Swaps The company enters into interest rate swap agreements to manage its exposure to interest rate changes and its overall cost of borrowing. The company's interest rate swap agreements were entered into to exchange variable rate interest payments for fixed rate payments over the life of the agreement without the exchange of the underlying notional amounts. The notional amount of the interest rate swap agreements is used to measure interest to be paid or received and does not represent the amount of exposure to credit loss. The differential paid or received on the interest rate swap agreements is recognized as an adjustment to interest expense. The interest rate swaps were designated cash flow hedges at inception and remain an effective accounting hedge as of March 3, 2018 . Since a designated derivative meets hedge accounting criteria, the fair value of the hedge is recorded in the Consolidated Statement of Stockholders’ Equity as a component of Accumulated other comprehensive loss, net of tax. The ineffective portion of the change in fair value of the derivatives is immediately recognized in earnings. The interest rate swap agreements are assessed for hedge effectiveness on a quarterly basis. In September 2016, the company entered into an interest rate swap agreement. The interest rate swap is for an aggregate notional amount of $150.0 million with a forward start date of January 3, 2018 and a termination date of January 3, 2028. As a result of the transaction, the company effectively converted indebtedness anticipated to be borrowed on the company’s revolving line of credit up to the notional amount from a LIBOR-based floating interest rate plus applicable margin to a 1.949 percent fixed interest rate plus applicable margin under the agreement as of the forward start date. On June 12, 2017, the company entered into an interest rate swap agreement. The interest rate swap is for an aggregate notional amount of $75.0 million with a forward start date of January 3, 2018 and a termination date of January 3, 2028. As a result of the transaction, the company effectively converted the company’s revolving line of credit up to the notional amount from a LIBOR-based floating interest rate plus applicable margin to a 2.387 percent fixed interest rate plus applicable margin under the agreement as of the forward start date. As of March 3, 2018 , the fair value of the company’s two outstanding interest rate swap agreements was an asset of $13.7 million . The asset fair value was recorded within Other noncurrent assets within the Condensed Consolidated Balance Sheets. The net unrealized gain recorded within Other comprehensive loss, net of tax, for the effective portion of the company's designated cash flow hedges was $5.9 million and $1.1 million for the three months ended March 3, 2018 and March 4, 2017 , respectively. The net unrealized gain recorded within Other comprehensive loss, net of tax, for the effective portion of the company's designated cash flow hedges was $6.9 million and $5.3 million for the nine months ended March 3, 2018 and March 4, 2017 , respectively. There were no gains or losses recognized against earnings for hedge ineffectiveness and there were no gains or losses reclassified from Accumulated other comprehensive loss into earnings for three and nine month periods ended March 3, 2018 and March 4, 2017

Contingencies And Contingencies	Commitments and Contingencies Product Warranties The company provides coverage to the end-user for parts and labor on products sold under its warranty policy and for other product-related matters. The standard length of warranty is 12 years for the majority of products sold; however, this varies depending on the product classification. The company does not sell or otherwise issue warranties or warranty extensions as stand-alone products. Reserves have been established for the various costs associated with the company's warranty program and are included in the Condensed Consolidated Balance Sheets under “Accrued warranty.” General warranty reserves are based on historical claims experience and other currently available information. These reserves are adjusted once an issue is identified and the actual cost of correction becomes known or can be estimated.

These arrangements are common in the industry and generally have terms ranging between one and three years. The bonds are required to provide assurance to customers that the products and services they have purchased will be installed and/or provided properly and without damage to their facilities. The bonds are provided by various bonding agencies. However, the company is ultimately liable for claims that may occur against them. As of March 3, 2018 , the company had a maximum financial exposure related to performance bonds totaling approximately $8.9 million . The company has no history of claims, nor is it aware of circumstances that would require it to pay, under any of these arrangements. The company also believes that the resolution of any claims that might arise in the future, either individually or in the aggregate, would not materially affect the company's financial statements. Accordingly, no liability has been recorded in respect to these bonds as of either March 3, 2018 or June 3, 2017 . The company has entered into standby letter of credit arrangements for purposes of protecting various insurance companies and lessors against default on insurance premium and lease payments. As of March 3, 2018 , the company had a maximum financial exposure from these standby letters of credit totaling approximately $8.2 million , all of which is considered usage against the company's revolving line of credit. The company has no history of claims, nor is it aware of circumstances that would require it to perform under any of these arrangements, and believes that the resolution of any claims that might arise in the future, either individually or in the aggregate, would not materially affect the company's financial statements. Accordingly, no liability has been recorded in respect of these arrangements as of March 3, 2018 and June 3, 2017 . Contingencies

The facility will expire in September 2021 and outstanding borrowings bear interest at rates based on the prime rate, federal funds rate, LIBOR or negotiated rates as outlined in the agreement. Interest is payable periodically throughout the period if borrowings are outstanding. On January 3, 2018, the company borrowed $225.0 million on its existing revolving line of credit. Of these proceeds, $150.0 million was used to repay its Series B senior notes, while the rest of the proceeds was used for general business purposes. As of March 3, 2018 , the total debt outstanding related to borrowings under the syndicated revolving line of credit was $225.0 million . Available borrowings against this facility were $166.8 million due to $8.2 million related to outstanding letters of credit. As of June 3, 2017, there were no outstanding borrowings against this facility and available borrowings were $357.1 million due to $8.3 million outstanding letters of credit. Supplier Financing Program The company has an agreement wit h a third party financial institution to provide a platform that allows certain participating suppliers the ability to finance payment obligations from the company. Under this program, participating suppliers may finance payment obligations of the company, prior to their scheduled due dates, at a discounted price to the third party financial institution. The company has lengthened the payment terms for certain suppliers that have chosen to participate in the program. As a result, certain amounts due to suppliers have payment terms that are longer than standard industry practice and as such, these amounts have been excluded from the caption “Accounts payable” in the Condensed Consolidated Balance Sheets as the amounts have been accounted for by the company as a current debt obligation. Accordingly, $3.3 million and $3.2 million have been recorded within the caption “Other accrued liabilities” for the periods ended March 3, 2018 and June 3, 2017 , respectively. Construction-Type Lease During fiscal 2015, the company entered into a lease agreement for the occupancy of a new studio facility in Palo Alto, California. In fiscal 2017, the company became the deemed owner of the leased building for accounting purposes as a result of the company's involvement during the construction phase of the project. The lease is therefore accounted for as a financing transaction and the building and related financing liability were initially recorded at fair value in the Consolidated Balance Sheets within both Construction in progress and Other accrued liabilities. The fair value of the building and financing liability was determined through a blend of an income approach, comparable property sales approach and a replacement cost approach. The value of the building and the related financing liability at March 3, 2018 and June 3, 2017 was $7.0 million

Redeemable Noncontrolling Interests	Redeemable Noncontrolling Interests Redeemable noncontrolling interests are reported on the Consolidated Balance Sheets in mezzanine equity in “Redeemable noncontrolling interests.” The company recognizes changes to the redemption value of redeemable noncontrolling interests as they occur and adjusts the carrying value to equal the redemption value at the end of each reporting period. The redemption amounts have been estimated based on the fair value of the subsidiary, determined based on a weighting of the discounted cash flow and market methods. This represents a level 3 fair value measurement. Changes in the company’s redeemable noncontrolling interests for the nine months ended March 3, 2018 and March 4, 2017 are as follows: (In millions) March 3, 2018 March 4, 2017 Beginning Balance $ 24.6 $ 27.0 Purchase of redeemable noncontrolling interests (1.0 ) (1.5 ) Net income attributable to redeemable noncontrolling interests 0.2 0.1 Redemption value adjustment 0.5 (0.7 ) Other adjustments — 0.1 Ending Balance $ 24.3 $ 25.0

Segment Reporting, Disclosure of Entity's Reportable Segments [Abstract]
Operating Segments	Operating Segments Effective in the first quarter of fiscal 2018, the company moved the operating results of its Nemschoff subsidiary, which primarily focuses on healthcare, from its North America Furniture Solutions operating segment to its Specialty operating segment. This change was made to better leverage the skills and capabilities of the company's Specialty business teams, particularly in the areas of craft wood and upholstery manufacturing. Additionally, the company has refreshed its methodology of allocating selling, general and administrative costs to the operating segments. The company has also identified certain corporate support costs that will no longer be allocated to the operating segments and that will be tracked and reported as "Corporate Unallocated Expenses". The company made these changes in the way that it allocates and reports its costs to better reflect the utilization of functional services across its operating segments and to also more closely align to industry practice. Prior year results disclosed in the table below have been revised to reflect these changes. The company's reportable segments consist of North American Furniture Solutions, ELA ("EMEA, Latin America, and Asia Pacific") Furniture Solutions, Specialty and Consumer. The North American Furniture Solutions segment includes the operations associated with the design, manufacture and sale of furniture products for work-related settings, including office, education and healthcare environments, throughout the United States and Canada. The business associated with the company's owned contract furniture dealers is also included in the North American Furniture Solutions segment. The ELA Furniture Solutions segment includes EMEA, Latin America and Asia-Pacific. ELA includes the operations associated with the design, manufacture, and sale of furniture products, primarily for work-related settings, in these geographic regions. The Specialty segment includes the operations associated with the design, manufacture, and sale of high-craft furniture products and textiles including Geiger wood products, Maharam textiles, Nemschoff and Herman Miller Collection products. The Consumer segment includes operations associated with the sale of modern design furnishings and accessories to third party retail distributors, as well as direct to consumer sales through eCommerce and Design Within Reach retail studios. The company also reports a “Corporate” category consisting primarily of unallocated expenses related to general corporate functions, including, but not limited to, certain legal, executive, corporate finance, information technology, administrative and acquisition-related costs. Management regularly reviews corporate costs and believes disclosing such information provides more visibility and transparency regarding how the chief operating decision maker reviews results of the Company. The accounting policies of the reportable operating segments are the same as those of the company.

Restructuring and Related Activities [Abstract]
Restructuring Expenses	Restructuring Expenses During the first quarter of fiscal 2018 , the company announced restructuring actions involving targeted workforce reductions primarily within the North American segment. These actions related to the company's cost savings initiatives and resulted in the recognition of restructuring expenses of $1.4 million in the first quarter of fiscal 2018 . The restructuring actions were completed at December 2, 2017, and final payments are expected to be made over the next quarter. During the second quarter of fiscal 2018 , the company announced further restructuring actions involving targeted workforce reductions primarily within the North American segment. These actions related to the company's previously announced cost savings initiatives and resulted in the recognition of restructuring expenses of $0.5 million in the second quarter of fiscal 2018 . The restructuring actions were completed at December 2, 2017, and final payments are expected to be made over the next three quarters. During the second and third quarters of fiscal 2017 , the company announced restructuring actions involving targeted workforce reductions within the North American, ELA and Specialty segments. These actions resulted in the recognition of restructuring expenses related to severance costs of $2.7 million and $3.7 million in the third quarter and nine month periods, respectively.

Accounting Policies [Abstract]
Recently Adopted Accounting Standards and Recently Issued Accounting Standards Not Yet Adopted	Recently Adopted Accounting Standards Standard Description Effective Date Effect on the Financial Statements or Other Significant Matters Improvements to Employee Share-Based Payment Accounting Under the new guidance, all excess tax benefits/deficiencies should be recognized as income tax expense/benefit, entities may elect how to account for forfeitures and cash paid by an employer when directly withholding shares for tax withholding purposes should be classified as a financing activity on the cash flow statement. June 4, 2017 The company adopted the accounting standard in the first quarter of fiscal 2018. As a result, the company elected to change its policy from estimating forfeitures to recognizing forfeitures when they occur, which resulted in an increase in Retained earnings of $0.1 million, a decrease in Additional paid in capital of $0.3 million and an increase in Other noncurrent assets of $0.2 million in the Condensed Consolidated Balance Sheets. The other impacts resulting from adoption did not have a material impact on the company's Financial Statements. Recently Issued Accounting Standards Not Yet Adopted Standard Description Effective Date Effect on the Financial Statements or Other Significant Matters Revenue from Contracts with Customers The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard is designed to create greater comparability for financial statement users across industries and jurisdictions and also requires enhanced disclosures. The standard allows for two adoption methods, a full retrospective or modified retrospective approach. June 3, 2018 The company has completed a preliminary review of the impact of the new standard and expects changes in the identification of performance obligations around product and service revenue. For commercial contracts in which the company sells directly to end customers, in most cases, the company currently delays revenue recognition until the products are shipped and installed and records third-party installation and certain other fees net. However, under the new standard, in most cases, the company will recognize product revenue when title and risk of loss have transferred and will recognize service revenue upon the completion of services. Additionally, the company will record certain product pricing elements related to its direct customer sales within revenue and Cost of Sales rather than net within revenue as is current practice. The company has determined that these elements relate to the product performance obligation which the company is considered to control under the new standard. The company is also in the process of implementing changes to its business processes, systems and controls to support recognition and disclosure under the new standard. The company expects to adopt the standard in fiscal 2019 using the modified retrospective approach. Standard Description Effective Date Effect on the Financial Statements or Other Significant Matters Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities The standard provides guidance for the measurement, presentation and disclosure of financial assets and liabilities. The standard requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and recognize any change in fair value in net income. The standard does not permit early adoption and at adoption a cumulative-effect adjustment to beginning retained earnings should be recorded. June 3, 2018 The company is currently evaluating the impact of adopting this guidance. Compensation - Retirement Benefits: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost This standard changes the rules related to the income statement presentation of the components of net periodic benefit cost for defined benefit pension and other postretirement benefit plans. Under the new guidance, entities must present the service cost component of net periodic benefit cost in the same income statement line items as other employee compensation costs related to services rendered during the period. Other components of net periodic benefit cost will be presented separately from the line items that include the service cost. Early adoption is permitted. June 3, 2018 The standard is expected to impact the classification of certain costs within the company's Consolidated Statements of Comprehensive Income. No impact to the company's Consolidated Balance Sheets or Consolidated Statements of Cash Flow are expected as a result of the standard. Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income This update allows for the reclassification to retained earnings of the tax effects stranded in Accumulated Other Comprehensive Income resulting from The Tax Cuts and Jobs Act. Early adoption is permitted. June 2, 2019 The company is still evaluating these amendments and has not determined its accounting policy and whether or not an election will be made to reclassify the stranded effects. Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities This update amends the hedge accounting recognition and presentation with the objectives of improving the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities and simplifying the application of hedge accounting. The update expands the strategies eligible for hedge accounting, relaxes the timing requirements of hedge documentation and effectiveness assessments and permits the use of qualitative assessments on an ongoing basis to assess hedge effectiveness. The new guidance also requires new disclosures and presentation. June 2, 2019 The company is currently evaluating the impact of adopting this guidance. Leases Under the updated standard a lessee's rights and obligations under most leases, including existing and new arrangements, would be recognized as assets and liabilities, respectively, on the balance sheet. The standard must be adopted under a modified retrospective approach and early adoption is permitted. June 2, 2019 The standard is expected to have a significant impact on our Consolidated Financial Statements; however, the company is currently evaluating the impact.
