                             SUPPLEMENTAL INDENTURE

     SUPPLEMENTAL INDENTURE (this "Supplemental Indenture"), dated as of April
10, 2001, among those guaranteeing subsidiaries named on the signature pages
hereto (each a "Guaranteeing Subsidiary", collectively the "Guaranteeing
Subsidiaries"), each a subsidiary of Sealy Mattress Company (or its permitted
successor), an Ohio corporation (the "Company"), the Company, the other
Guarantors (as defined in the Indenture referred to herein) and The Bank of New
York, as trustee under the indenture referred to below (the "Trustee").

                                   WITNESSETH

     WHEREAS, the Company has heretofore executed and delivered to the Trustee
an indenture (the "Indenture"), dated as of December 18, 1997 providing for the
issuance of an aggregate principal amount of up to $300.0 million of 9-7/8%
Senior Subordinated Notes due 2007 (the "Notes");

     WHEREAS, the Indenture provides that under certain circumstances each
Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental
indenture pursuant to which such Guaranteeing Subsidiary shall unconditionally
guarantee all of the Company's Obligations under the Notes and the Indenture on
the terms and conditions set forth herein (the "Note Guarantee"); and

     WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is
authorized to execute and deliver this Supplemental Indenture.

     NOW THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, the receipt of which is hereby acknowledged, each
Guaranteeing Subsidiary and the Trustee mutually covenant and agree for the
equal and ratable benefit of the Holders of the Notes as follows:

     1. CAPITALIZED TERMS. Capitalized terms used herein without definition
shall have the meanings assigned to them in the Indenture.

     2. AGREEMENT TO GUARANTEE. Each Guaranteeing Subsidiary hereby agrees as
follows:

     (a)  Along with all Guarantors named in the Indenture, to jointly and
          severally Guarantee to each Holder of a Note authenticated and
          delivered by the Trustee and to the Trustee and its successors and
          assigns, irrespective of the validity and enforceability of the
          Indenture, the Notes or the obligations of the Company hereunder or
          thereunder, that:

          (i)  the principal of and interest on the Notes will be promptly paid
               in full when due, whether at maturity, by acceleration,
               redemption or otherwise, and interest on the overdue principal of
               and interest on the Notes, if any, if lawful, and all other
               obligations of the Company to the Holders or the Trustee
               hereunder or thereunder



               will be promptly paid in full or performed, all in accordance
               with the terms hereof and thereof; and

          (ii) in case of any extension of time of payment or renewal of any
               Notes or any of such other obligations, that same will be
               promptly paid in full when due or performed in accordance with
               the terms of the extension or renewal, whether at stated
               maturity, by acceleration or otherwise. Failing payment when due
               of any amount so guaranteed or any performance so guaranteed for
               whatever reason, the Guarantors shall be jointly and severally
               obligated to pay the same immediately.

     (b)  The obligations hereunder shall be unconditional, irrespective of the
          validity, regularity or enforceability of the Notes or the Indenture,
          the absence of any action to enforce the same, any waiver or consent
          by any Holder of the Notes with respect to any provisions hereof or
          thereof, the recovery of any judgment against the Company, any action
          to enforce the same or any other circumstance which might otherwise
          constitute a legal or equitable discharge or defense of a guarantor.

     (c)  The following is hereby waived: diligence, presentment, demand of
          payment, filing of claims with a court in the event of insolvency or
          bankruptcy of the Company, any right to require a proceeding first
          against the Company, protest, notice and all demands whatsoever.

     (d)  This Note Guarantee shall not be discharged except by complete
          performance of the obligations contained in the Notes and the
          Indenture.

     (e)  If any Holder or the Trustee is required by any court or otherwise to
          return to the Company, the Guarantors, or any custodian, Trustee,
          liquidator or other similar official acting in relation to either the
          Company or the Guarantors, any amount paid by either to the Trustee or
          such Holder, this Note Guarantee, to the extent theretofore
          discharged, shall be reinstated in full force and effect.

     (f)  The Guaranteeing Subsidiary shall not be entitled to any right of
          subrogation in relation to the Holders in respect of any obligations
          guaranteed hereby until payment in full of all obligations guaranteed
          hereby.

     (g)  As between the Guarantors, on the one hand, and the Holders and the
          Trustee, on the other hand, (x) the maturity of the obligations
          guaranteed hereby may be accelerated as provided in Article 6 of the
          Indenture for the purposes of this Note Guarantee, notwithstanding any
          stay, injunction or other prohibition preventing such acceleration in
          respect of the obligations guaranteed hereby, and (y) in the event of
          any declaration of acceleration of such obligations as provided in
          Article 6 of the Indenture, such

                                        2



          obligations (whether or not due and payable) shall forthwith become
          due and payable by the Guarantors for the purpose of this Note
          Guarantee.

     (h)  The Guarantors shall have the right to seek contribution from any
          non-paying Guarantor so long as the exercise of such right does not
          impair the rights of the Holders under the Guarantee.

     (i)  Pursuant to Section 11.02 of the Indenture, after giving effect to any
          maximum amount and any other contingent and fixed liabilities that are
          relevant under any applicable Bankruptcy or fraudulent conveyance
          laws, and after giving effect to any collections from, rights to
          receive contribution from or payments made by or on behalf of any
          other Guarantor in respect of the obligations of such other Guarantor
          under Article 11 of the Indenture shall result in the obligations of
          such Guarantor under its Note Guarantee not constituting a fraudulent
          transfer or conveyance.

     3. EXECUTION AND DELIVERY. Each Guaranteeing Subsidiary agrees that the
Note Guarantees shall remain in full force and effect notwithstanding any
failure to endorse on each Note a notation of such Note Guarantee.

     4. GUARANTEEING SUBSIDIARY MAY CONSOLIDATE, ETC. ON CERTAIN TERMS.

     (a)  No Guaranteeing Subsidiary may consolidate with or merge with or into
          (whether or not such Guarantor is the surviving Person) another
          corporation, Person or entity whether or not affiliated with such
          Guarantor unless:

          (i)  subject to Section 11.05 of the Indenture, the Person formed by
               or surviving any such consolidation or merger (if other than a
               Guarantor or the Company) unconditionally assumes all the
               obligations of such Guarantor, pursuant to a supplemental
               indenture in form and substance reasonably satisfactory to the
               Trustee, under the Notes, the Indenture and the Note Guarantee on
               the terms set forth herein or therein; and

          (ii) immediately after giving effect to such transaction, no Default
               or Event of Default exists.

     (b)  In case of any such consolidation, merger, sale or conveyance and upon
          the assumption by the successor corporation, by supplemental
          indenture, executed and delivered to the Trustee and satisfactory in
          form to the Trustee, of the Note Guarantee endorsed upon the Notes and
          the due and punctual performance of all of the covenants and
          conditions of the Indenture to be performed by the Guarantor, such
          successor corporation shall succeed to and be substituted for the
          Guarantor with the same effect as if it had been named herein as a
          Guarantor. Such successor corporation

                                        3



          thereupon may cause to be signed any or all of the Note Guarantees to
          be endorsed upon all of the Notes issuable hereunder which theretofore
          shall not have been signed by the Company and delivered to the
          Trustee. All the Note Guarantees so issued shall in all respects have
          the same legal rank and benefit under the Indenture as the Note
          Guarantees theretofore and thereafter issued in accordance with the
          terms of the Indenture as though all of such Note Guarantees had been
          issued at the date of the execution hereof.

     (c)  Except as set forth in Articles 4 and 5 of the Indenture, and
          notwithstanding clauses (a) and (b) above, nothing contained in the
          Indenture or in any of the Notes shall prevent any consolidation or
          merger of a Guarantor with or into the Company or another Guarantor,
          or shall prevent any sale or conveyance of the property of a Guarantor
          as an entirety or substantially as an entirety to the Company or
          another Guarantor.

     5. RELEASES.

     (a)  in the event of a sale or other disposition of all of the assets of
          any Guarantor, by way of merger, consolidation or otherwise, or a sale
          or other disposition of all of the capital stock of any Guarantor,
          then such Guarantor (in the event of a sale or other disposition, by
          way of merger, consolidation or otherwise, of all of the capital stock
          of such Guarantor) or the corporation acquiring the property (in the
          event of a sale or other disposition of all or substantially all of
          the assets of such Guarantor) will be released and relieved of any
          obligations under its Note Guarantee; provided that the Net Proceeds
          of such sale or other disposition are applied in accordance with the
          applicable provisions of the Indenture, including without limitation
          Section 4.10 of the Indenture. Upon delivery by the Company to the
          Trustee of an Officers' Certificate and an Opinion of Counsel to the
          effect that such sale or other disposition was made by the Company in
          accordance with the provisions of the Indenture, including without
          limitation Section 4.10 of the Indenture, the Trustee shall execute
          any documents reasonably required in order to evidence the release of
          any Guarantor from its obligations under its Note Guarantee.

     (b)  Any Guarantor not released from its obligations under its Note
          Guarantee shall remain liable for the full amount of principal of and
          interest on the Notes and for the other obligations of any Guarantor
          under the Indenture as provided in Article 10 of the Indenture.

                                        4



     6. NO RECOURSE AGAINST OTHERS. No past, present or future director,
officer, employee, incorporator, stockholder or agent of any Guaranteeing
Subsidiary, as such, shall have any liability for any obligations of the Company
or any other Guaranteeing Subsidiary under the Notes, any Note Guarantees, the
Indenture or this Supplemental Indenture or for any claim based on, in respect
of, or by reason of, such obligations or their creation. Each Holder of the
Notes by accepting a Note waives and releases all such liability. The waiver and
release are part of the consideration for issuance of the Notes. Such waiver may
not be effective to waive liabilities under the federal securities laws and it
is the view of the Commission that such a waiver is against public policy.

     7. NEW YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL
GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE BUT WITHOUT GIVING
EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE
APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

     8. COUNTERPARTS. The parties may sign any number of copies of this
Supplemental Indenture. Each signed copy shall be an original, but all of them
together represent the same agreement.

     9. EFFECT OF HEADINGS. The Section headings herein are for convenience only
and shall not affect the construction hereof.

     10. THE TRUSTEE. The Trustee shall not be responsible in any manner
whatsoever for or in respect of the validity or sufficiency of this Supplemental
Indenture or for or in respect of the recitals contained herein, all of which
recitals are made solely by each Guaranteeing Subsidiary and the Company.

                                        5



     IN WITNESS WHEREOF, the parties hereto have caused this Supplemental
Indenture to be duly executed and attested, all as of the date first above
written.
