Tempur Sealy International, Inc. TPX is pushing forward with its plans to acquire Mattress Firm, despite an ongoing legal challenge from the Federal Trade Commission. The company has agreed to sell its Sleep Outfitters subsidiary and a portion of Mattress Firm’s footprint.

Tempur Sealy International has reached a deal to sell dozens of Mattress Firm locations and the Sleep Outfitters retail chain to Mattress Warehouse as it works through a regulatory challenge to its planned acquisition of Mattress Firm.

Tempur Sealy International said it has taken steps to get its planned $4 billion takeover of rival Mattress Firm approved by regulators.
