Exhibit 99.1

FOR IMMEDIATE RELEASE: APRIL 30, 2015

LEGGETT & PLATT REPORTS $.50 EPS, A FIRST QUARTER RECORD

Carthage, MO, April 30, 2015 —

Diversified manufacturer Leggett & Platt reported earnings of $.50 per share, a first quarter record. In 2014, first quarter EPS was $.37, including a small loss from discontinued operations. The 2015 EPS improvement is largely the result of strong unit volume growth; this was partially offset by a $6 million pre-tax impairment charge in the Industrial Segment’s Steel Tubing business unit.

Sales from continuing operations were $966 million, a first quarter record, and a 10.4% increase versus the prior year. Same location sales improved 5.6%; unit volume grew 8.5%, but was partially offset by currency impacts and raw material-related price deflation. Acquisitions contributed 4.8% to sales growth.

EBIT margin improved 180 basis points versus first quarter last year, from 9.8% to 11.6%, as a result of higher sales, pricing discipline, and efficiency improvements.

CEO Comments

Board Chair and CEO David S. Haffner commented, “We are very pleased with our start to 2015. During the first quarter we achieved strong volume gains and higher margins, which led to record first quarter EPS. For the full year, we expect to achieve similar results: record sales from continuing operations, our highest EBIT margin since 2000, and record EPS.

“Improvement in demand was broad-based, with nearly all of our business units experiencing volume growth during the quarter. We continue to benefit in particular from the bedding market’s shift to Comfort Core springs, from significant new programs our Adjustable Bed unit won in 2014, and from ongoing content gains and new program awards in our Automotive business.

“During the quarter we completed the acquisition of a European private-label manufacturer of high-end upholstered furniture generally used in office and commercial settings. This business complements our existing North American private-label operation, allowing us to support our Work Furniture customers as they expand globally.

“Since 2007, our primary financial goal has been to achieve Total Shareholder Return (TSR¹) that ranks in the top third of the S&P 500 companies. For the three year period that began January 1, 2013, we have so far (over the last 28 months) generated TSR performance that ranks in the top 34 percent of the S&P 500.”

Dividends and Stock Repurchases

In February, Leggett & Platt’s Board of Directors declared a $.31 first quarter dividend, one cent higher than last year’s first quarter dividend. Thus, 2015 marks the 44^th consecutive annual dividend increase for the company, with a compound annual growth rate of 13%. Only one other S&P 500 company can claim as high a rate of dividend growth for as many years. Leggett & Platt is proud of its dividend record and plans to continue it.

At yesterday’s closing share price of $43.23, the indicated annual dividend of $1.24 per share generates a dividend yield of 2.9%, one of the strongest dividend yields among the 52 stocks of the S&P 500 Dividend Aristocrats.

During the first quarter the company purchased 1.5 million shares of its stock at an average price of $44.53, and issued 1.5 million shares through employee benefit plans and option exercises. The number of shares outstanding was unchanged at 137.8 million.

Strategy and TSR Results

In 2007, the company made a significant change by adjusting its primary focus from pursuing revenue to pursuing TSR. As a result, L&P’s principal long-term financial goal is to generate TSR that ranks in the top third of the S&P 500 over rolling 3-year periods.

The company’s strategy to achieve this goal is to utilize a balanced approach that generates TSR via four drivers: revenue, margin, dividends, and share count. Accordingly, the company annually strives to concurrently: i) grow revenue 4-5%, ii) improve margin 20-30 basis points, iii) provide an attractive dividend yield, and iv) reduce shares outstanding. One-half of the revenue growth should come from typical GDP expansion, and one-half from the company’s internal efforts to increase market share, introduce innovative products, and make prudent, strategic acquisitions.

This balanced approach has generated consistently higher TSR, with lower risk and volatility, than the prior approach focused primarily on revenue growth. For the three years ending December 2014, L&P generated compound annual TSR of 28% per year, which ranked in the top quarter of the S&P 500, exceeding the company’s top-third goal. Since adopting this TSR focus in late 2007, the company’s cumulative TSR ranks among the top 13% of the S&P 500. Through March 2015, an end-of-2007 investment in Leggett & Platt stock more than tripled in value (i.e. 274% return) if dividends were reinvested, significantly outperforming the 65% return of the S&P 500 index.

2015 Records Anticipated

For 2015, the company expects record sales from continuing operations, its highest EBIT margin since 2000, and another year of record EPS. The company is raising the low end of its prior EPS guidance, and now projects 2015 EPS of $1.95 - 2.10 on sales of $3.9 - 4.1 billion, or 3% - 8% growth.

Cash from operations should exceed $350 million in 2015. Capital expenditures are expected to be roughly $120 million, and dividend payments should approximate $170 million.

As has been the company’s practice, after funding dividends and capital expenditures, remaining cash flow will be prioritized toward competitively advantaged acquisitions. Potential acquisitions must meet stringent strategic and financial criteria. Should no acquisitions come to fruition, and if excess cash flow is available, the company has standing authorization from the Board of Directors to repurchase up to 10 million shares each year. No specific share repurchase commitment or timetable has been established; however, the company currently anticipates the purchase of between 3 and 5 million shares during 2015, and the issuance of approximately 3 million shares via employee benefit plans and option exercises.

SEGMENT RESULTS – First Quarter 2015 (versus the same period in 2014)

Historical financial amounts reflect the new segment structure described below.

Residential Furnishings – Total sales increased $81 million, or 18%. Same location sales improved 10%, with higher unit volume in most product categories partially offset by the impact of currency translation. EBIT (earnings before interest and income taxes) increased $5 million primarily due to higher sales; this was partially offset by nonrecurrence of last year’s $4 million gain on sale of a building.

2 of 5

Commercial Products – Total sales increased $24 million, or 21%. Same location sales grew 17%, primarily from strong demand growth in the Adjustable Bed unit. EBIT increased $2 million due to higher sales.

Industrial Materials – Total sales increased $12 million, or 6%, with higher unit volume of drawn wire partially offset by steel-related price decreases. EBIT increased $0.3 million; the increase generated from higher volume was offset by a $6 million impairment charge in the Steel Tubing business unit.

Specialized Products – Total sales increased $13 million, or 6%. Strong demand for the company’s automotive components was partially offset by the impact of currency translation. EBIT increased $12 million primarily due to increased volumes; productivity improvements in the European aerospace operations also contributed.

Revised Segment Structure

As disclosed in its 8-K filed on April 16, the company reorganized its operating segment structure, given the divestiture last year of the majority of the Store Fixtures operations, and the recent retirement of one of the operating segment presidents. The 18 business units are now organized as follows:
