	This Amendment No. 4 to Schedule 13D relates to the Common Stock, par
value of $0.01 per share (the "Common Stock") of Sealy Corporation, a
Delaware corporation (the "Issuer"), which has its principal executive office
at Sealy Drive, One Office Parkway, Trinity, North Carolina 27370.  This
Amendment No. 4 amends and supplements, as set forth below, the initial
Schedule 13D, filed January 9, 2012, and the Amendment No. 1 to Schedule 13D,
filed February 14, 2012, on behalf of BART Partners, LLC, and the Amendment
No. 2 to Schedule 13D, filed March 29, 2012, jointly on behalf of FPR Partners,
LLC and BART Partners, LLC, and the Amendment No. 3 to Schedule 13D filed
June 8, 2012, on behalf of FPR Partners, LLC relating to the Common Stock
collectively, the "Schedule 13D").


Item 4.     Purpose of Transaction
            ----------------------

	Item 4 of the Schedule 13D is hereby amended and supplemented as
follows:

The Reporting Person is filing this Amendment No. 4 to report recent
open-market sales of securities of the Issuer that have decreased the amount
of Common Stock that the Reporting Person may be deemed to beneficially own
by an amount greater than one percent of the outstanding Common Stock of the
Issuer. The disposition of the securities of the Issuer by the Reporting
Person was an investment decision based upon the Reporting Person's
determination of several factors, including, without limitation, the market
price for such securities and the plan of merger publicly announced by the
Issuer on September 27, 2012.

Item 5.    Interest in Securities of the Issuer

the Issuer's Common Stock.

	(b)	The Reporting Person has and will have the sole power to

Item 6.     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.
