Retirement Benefits [Abstract] |
Retirement Plans | Retirement Plans 401(k) Plan The Company has a defined contribution plan ("the 401(k) Plan") whereby eligible employees may contribute up to 85.0% of their pay subject to certain limitations as defined by the 401(k) Plan. Employees are eligible to participate in the 401(k) Plan upon hire and are eligible to receive matching contributions upon six months of continuous employment with the Company. The 401(k) Plan provides a 100.0% match of the first 3.0% and 50.0% of the next 2.0% of eligible employee contributions. The match for union employees is based on the applicable collective bargaining arrangement. All matching contributions vest immediately. The Company incurred $5.8 million, $6.0 million and $5.8 million of expenses associated with the 401(k) Plan for the years ended December 31, 2020, 2019 and 2018, respectively, which are included in the Consolidated Statements of Income. Defined Benefit Pension Plans The Company has a noncontributory, defined benefit pension plan covering current and former hourly employees at two of its active Sealy plants and ten previously closed Sealy U.S. facilities. Sealy Canada, Ltd. (a wholly-owned subsidiary of the Company) also sponsors a noncontributory, defined benefit pension plan covering hourly employees at one of its facilities (collectively, referred to as the "Plans"). The Plans provide retirement and survivorship benefits based on the employees’ credited years of service. The Company’s funding policy provides for contributions of an amount between the minimum required and maximum amount that can be deducted for federal income tax purposes. The Plans' assets consist of investments in various common/collective trusts with equity investment strategies diversified across multiple industry sectors and company market capitalization within specific geographical investment strategies, fixed income common/collective trusts, which invest primarily in investment-grade and high-yield corporate bonds and U.S. treasury securities, as well as money market mutual funds. The fixed income investments are diversified as to ratings, maturities, industries and other factors. The Plans' assets contain no significant concentrations of risk related to individual securities or industry sectors. The Plans have no direct investment in the Company's common stock. The long-term rate of return for the Plans is based on the weighted average of the Plans’ investment allocation and the historical returns for those asset categories. Because future compensation levels are not a factor in these Plans' benefit formulas, the accumulated benefit obligation is equal to the projected benefit obligation as reported below. The discount rate is based on the returns on long-term bonds in the private sector and incorporates a long-term inflation rate. Summarized information for the Plans follows: Expenses and Status The Company recognizes the service cost component of net periodic pension cost within general, administrative and other expenses and all other components of net periodic pension cost are recognized within other income, net, in the accompanying Consolidated Statements of Income. Components of total net periodic pension cost for the years ended December 31 were as follows:

Pension Plan Asset Information Investment Objective and Strategies The Company's investment objectives are to minimize the volatility of the value of the Company's pension assets relative to pension liabilities and to ensure assets are sufficient to pay plan benefits. Target and actual asset allocations are as follows:
| 2020 Target |  | 2020 Actual
Common/collective trust consisting primarily of: |  |  |
Equity securities | 60.0 | % |  | 56.6 | %
Debt securities | 40.0 | % |  | 43.1 | %
Other | — | % |  | 0.3 | %
Total plan assets | 100.0 | % |  | 100.0 | %
Investment strategies and policies reflect a balance of risk-reducing and return-seeking considerations. The objective of minimizing the volatility of assets relative to liabilities is addressed primarily through asset diversification. Assets are broadly diversified across many asset classes to achieve risk-adjusted returns that, in total, lower asset volatility relative to liabilities. The Company's policy to rebalance the Company's investment regularly ensures that actual allocations are in line with target allocations as appropriate. Strategies to address the goal of ensuring sufficient assets to pay benefits include target allocations to a broad array of asset classes that provide return, diversification and liquidity. The plan investment fiduciaries are responsible for setting asset allocation targets, and monitoring asset allocation and investment performance. The Company’s pension investment manager has discretion to manage assets to ensure compliance with the asset allocations approved by the plan fiduciaries. Significant Concentrations of Risk Significant concentrations of risk in the Company's plan assets relate to equity, interest rate, and operating risk. In order to ensure assets are sufficient to pay benefits, a portion of plan assets is allocated to equity investments that are expected, over time, to earn higher returns with more volatility than fixed income investments which more closely match pension liabilities. Within the common/collective trusts, the plan assets contain no significant concentrations of risk related to individual securities or industry sectors. In order to minimize asset volatility relative to the liabilities, a portion of the plan assets are allocated to fixed income investments that are exposed to interest rate risk. Rate increases will generally result in a decline in fixed income assets while reducing the present value of the liabilities. Conversely, rate decreases will increase fixed income assets, partially offsetting the related increase in the liabilities. Operating risks primarily include the risks of inadequate diversification and insufficient oversight. To mitigate this risk, investments are diversified across and within asset classes in support of investment objectives. Policies and practices to address operating risks include ongoing oversight, plan and asset class investment guidelines, and periodic reviews against these guidelines to ensure adherence. Expected Long-Term Return on Plan Assets The expected long-term return assumption at December 31, 2020 was 5.75% for the defined benefit pension plan for U.S. Sealy employees and 4.30% for the defined benefit pension plan for Sealy Canada, Ltd. The expected long-term return assumption is based on historical and projected rates of return for current and planned asset classes in the plan’s investment portfolio. The assumption considers various sources, primarily inputs from advisors for long-term capital market returns, inflation, bond yields, and other variables, adjusted for specific aspects of the Company's investment strategy by plan. The investments in plan assets primarily consist of common collective trusts and money market funds. Investments in common collective trusts and money market funds are valued at the net asset value ("NAV") per share or unit multiplied by the number of shares or units held as of the measurement date. The determination of NAV for the common/collective trusts includes market pricing of the underlying assets as well as broker quotes and other valuation techniques that represent fair value as determined by the respective administrator of the common/collective trust. Management has determined that the NAV is an appropriate estimate of the fair value of the common collective trusts at December 31, 2020 and 2019, based on the fact that the common/collective trusts are audited and accounted for at fair value by the administrators of the respective common/collective trusts. The methods described above may produce a fair value that may not be indicative of net realizable value or reflective of future fair value. Furthermore, while the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the Consolidated Balance Sheet dates. The fair value of the Company’s plan assets, all valued at NAV, at December 31 by asset category was as follows:
(in millions) | 2020 |  | 2019
Asset Category |  |  |
Common/collective trust |  |  |
U.S. equity | $ | 6.5 |  |  | $ | 5.5 |
International equity | 11.2 |  |  | 9.5 |
Total equity based funds | 17.7 |  |  | 15.0 |
Common/collective trust - fixed income | 13.5 |  |  | 11.9 |
Money market funds | 0.1 |  |  | 0.1 |
Total | $ | 31.3 |  |  | $ | 27.0 |
Multi‑Employer Benefit Plans Approximately 22.6% of the Company's domestic employees are represented by various labor unions with separate collective bargaining agreements. Hourly employees working at six of the Company's domestic manufacturing facilities are covered by union sponsored retirement plans. Further, employees working at three of the Company's domestic manufacturing facilities are covered by union sponsored health and welfare plans. These plans cover both active employees and retirees. Through the health and welfare plans, employees receive medical, dental, vision, prescription and disability coverage. The Company's cost associated with these plans consists of periodic contributions to these plans based upon employee participation. The expense recognized by the Company for such contributions for the years ended December 31 was follows:
(in millions) | 2020 |  | 2019 |  | 2018
Multi‑employer retirement plan expense | $ | 4.6 |  |  | $ | 4.3 |  |  | $ | 3.9 |
Multi‑employer health and welfare plan expense | 3.4 |  |  | 3.8 |  |  | 3.6 |
The risks of participating in multi‑employer pension plans are different from the risks of sponsoring single‑employer pension plans in the following respects: 1) contributions to the multi‑employer plan by one employer may be used to provide benefits to employees of other participating employers; 2) if a participating employer ceases its contributions to the plan, the unfunded obligations of the plan allocable to the withdrawing employer may be borne by the remaining participating employers; and 3) if the Company withdraws from the multi‑employer pension plans in which it participates, the Company may be required to pay those plans an amount based on its allocable share of the underfunded status of the plan. The following table presents information regarding the multi‑employer pension plans that are significant to the Company for the years ended December 31, 2020 and 2019, respectively:

(1) The Pension Protection Act of 2006 ranks the funded status of multi-employer pension plans depending upon a plan's current and projected funding. A plan is in the Red Zone (Critical) if it has a current funded percentage of less than 65.0%. A plan is in the Yellow Zone (Endangered) if it has a current funded percentage of less than 80.0%, or projects a credit balance deficit within seven years. A plan is in the Green Zone (Healthy) if it has a current funded percentage greater than 80.0% and does not have a projected credit balance deficit within seven years. The zone status is based on the plan’s year end rather than the Company's. The zone status listed for each plan is based on information that the Company received from that plan and is certified by that plan’s actuary for the most recent year available. (2) Funding Improvement Plan or Rehabilitation Plan as defined in the Employee Retirement Income Security Act of 1974 has been implemented or is pending. (3) Indicates whether the Company paid a surcharge to the plan in the most current year due to funding shortfalls and the amount of the surcharge. (4) The Company represented more than 5.0% of the total contributions for the most recent plan year available. For year ended December 31, 2018, the Company contributed $0.7 million to the plan.
