Somnigroup: How It Plans To Dominate The Mattress Market

Somnigroup International Inc. (SGI) has acquired Mattress Firm, the largest retailer of specialty mattresses in the U.S., and is simultaneously preparing to complete its acquisition of the largest supplier of components, Leggett & Platt, enabling it to dominate the mattress market.

Somnigroup earns a Buy rating and $100 price target, driven by its acquisition of Mattress Firm and pending Leggett & Platt deal. SGI is building a soft monopoly, leveraging omnichannel dominance, pricing power, and a robust balance sheet to expand margins by 2027. Q1 results show 12.3% net sales growth, 19.7% adj EBITDA growth, and $186M FCF, reflecting strong operating leverage and acquisition synergies. Key catalysts include the Leggett & Platt integration, Stearns & Foster hybrid launch, and $50M sales uplift from delayed price increases in H2.
