SCHEDULE 13D ------------------------- ------------------------- CUSIP NO. 812139301 Page 4 of 6 -------------------------------------------------------------------------------- Item 5. Interest in Securities of the Issuer ------------------------------------ 	The ownership percentages set forth herein are based on 104,082,411 shares of the Issuer's Common Stock outstanding as of September 20, 2012, as set forth in the Quarterly Report on Form 10-Q filed by the Issuer with the Securities and Exchange Commission on September 28, 2012.

Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer 	 ------------------------------------------------------------- 	The Reporting Person holds 800,840 of Issuer's 8% Senior Secured Third Lien Convertible Notes due 2016 (the "Notes"). The Notes are convertible into 23,421,767 shares of Issuer's Common Stock. However, based on the Prospectus Supplement of Sealy Corporation dated April 9, 2009 (the "Prospectus"), the Reporting Person is required to provide 61 days' notice to the Issuer in order to receive shares of Issuer's Common Stock upon conversion of the Notes. According to the Prospectus, no holder of the Notes (other than Kohlberg Kravis Roberts & Co. L.P., its affiliates and certain members of management) will be permitted to receive shares upon conversion of the Notes to the extent such conversion will result in such holder becoming a "beneficial owner" under the securities laws by owning 5% or more of the shares of Issuer's Common Stock. In addition, no holder of more than 5% of Issuer's Common Stock at May 27, 2009 (other than Kohlberg Kravis Roberts & Co. L.P., its affiliates and certain members of management) may receive shares upon conversion of the Notes to the extent such conversion will result in such holder becoming a "beneficial owner," directly or indirectly, of more than an additional 1% of the shares of Common Stock upon conversion of the Notes. These limitations on beneficial ownership shall be terminated (i) upon 61 days' notice to the Issuer by any holder of Notes, solely with respect to the Notes beneficially owned by such holder, (ii) immediately upon delivery by the Issuer of notice of its election to terminate conversion rights to the extent permitted by the indenture governing the Notes, (iii) immediately upon delivery by the Issuer of notice of a fundamental change or (iv) on June 15, 2016. 	Except as described above, there are no contracts, arrangements, understandings or relationships (legal or otherwise) among the Reporting Person or between such persons and any other person with respect to any securities of the Issuer, including but not limited to the transfer or voting of any securities of the Issuer, finder's fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, divisions of profits or loss, or the giving or withholding of proxies.
