The Doraville, Georgia-based company, whose roots date to 1870, filed for Chapter 11 protection from creditors on Monday night with the U.S. Bankruptcy Court in the Southern District of Texas.
Its prepackaged bankruptcy plan calls for debt to be reduced to $300 million from $1.9 billion.
Serta Simmons also lined up $125 million in financing to keep operating, including to pay its 3,600 employees.
It hopes to win court approval for its restructuring as soon as May 8.
The company's brands include Serta, Simmons, Beautyrest and Tuft & Needle. Sales totaled $2.4 billion in the year ending June 30, 2022.
In a court filing, Chief Financial Officer John Linker said a 2020 restructuring that added $200 million of new capital at first enabled Serta Simmons to weather higher raw material costs and supply chain disruptions caused by the COVID-19 pandemic.
But he said significant amounts of debt maturing in 2023 make the company's capital structure unsustainable, necessitating a comprehensive restructuring that is now supported by more than three-quarters of its key lenders.
Some lenders, including funds managed by Angelo Gordon & Co and Apollo Global Management, have sued to modify or undo the 2020 restructuring.
Serta Simmons wants all of that litigation put on hold during the bankruptcy, and on Tuesday filed its own lawsuit in the Texas bankruptcy court to resolve the lenders' claims and validate the 2020 restructuring.
Angelo Gordon declined to comment. Apollo did not immediately respond to requests for comment on Tuesday.
Serta Simmons' advisers include the law firm Weil, Gotshal & Manges, Evercore Group LLC and FTI Consulting Inc.
The case is In re Serta Simmons Bedding LLC et al, U.S. Bankruptcy Court, Southern District of Texas, No. 23-bk-90020.
