Tempur Sealy at the time said the deal was subject to customary closing conditions and expected it to close in the second half of 2024. But the FTC had other ideas, choosing to block the sale. The FTC rationale was that Tempur Sealy's manufacturing and supply chain operations, coupled with Mattress Firm's store network, would create "enormous power" at the merged entity. The FTC also said the combination would allow the new company to suppress competition and raise prices for mattresses that would impact millions of customers.
