Leggett & Platt shareholders voted on 20 August 2026 to approve an all-stock acquisition by Somnigroup International valued at $2.5 billion. The exchange ratio is 0.1455 Somnigroup shares for each Leggett & Platt share, leaving Leggett holders with roughly 9% of the combined company. Leggett & Platt produces specialty polyurethane foam for bedding and furniture through its Elite Comfort Solutions division; Somnigroup owns Tempur Sealy, Mattress Firm and Dreams. According to PU Magazine International, the combined business would have had around $11.2 billion of 2025 sales, more than 36,000 employees and 175 manufacturing sites in 36 countries, with expected annual adjusted EBITDA synergies of $50 million. Completion is expected by the end of 2026, subject to one remaining regulatory approval.
The vote closes the shareholder step of a deal agreed on 13 April 2026. Leggett & Platt’s own filing with the US Securities and Exchange Commission on 20 August confirms the approval, the date of the merger agreement and the fact that one regulatory clearance is still outstanding. It does not restate the financial terms: the exchange ratio, the ownership split, the combined sales, headcount, site count and synergy figure trace back to the April announcement and are reported here as carried by PU Magazine International.
The polyurethane content of the transaction sits in Elite Comfort Solutions, Leggett & Platt’s specialty foam division supplying bedding and furniture producers from the group’s base in Carthage, Missouri. Somnigroup brings the demand side: Tempur Sealy in manufacturing and branding, Mattress Firm in US retail and Dreams in the UK. The combination places a large Western merchant foam producer inside the group that also controls a significant share of the shelf space its output reaches.
The stated synergy target of $50 million in annual adjusted EBITDA is modest against roughly $11.2 billion of combined 2025 sales, which suggests the case rests more on supply security and channel control than on cost extraction. The all-stock structure, with former Leggett holders left at about 9%, leaves no ambiguity about which side holds control of the resulting group.
For suppliers of flexible and viscoelastic foam systems the question is where merchant volume still sits. Foam that moves between a manufacturer and a retailer inside one group is bought on internal transfer terms, so each combination of this kind takes tonnage out of the open market in bedding grades. What remains is a more fragmented mid-market of regional mattress producers, plus a shrinking number of very large accounts whose qualification cycles, audit requirements and documentation demands are heavier in proportion to their size.
