Sleep Number
Sleep Number, originally founded as Select Comfort in 1987, built its business around adjustable air-chamber mattress technology that lets each side of a bed be independently inflated to a specific personalized firmness level, identified by the company's proprietary numbered "Sleep Number" scale. The company's extensive network of dedicated retail showrooms, where customers can test different Sleep Number settings before purchasing, differentiated its sales approach from both traditional mattress retailers and the newer wave of direct-to-consumer, ship-in-a-box mattress competitors. Sleep Number's later expansion into smart mattress technology, including biometric tracking features that monitor a sleeper's heart rate, breathing, and movement through the mattress itself, reflected a broader company strategy of positioning its beds as health and wellness technology products rather than purely traditional bedding. Sleep Number's combination of its distinctive personalized adjustable-firmness technology and its later expansion into biometric sleep-tracking features has made it one of the most technologically differentiated mattress brands in the industry.
VS
Serta
Serta was founded in 1931 during the Great Depression as a cooperative of independent mattress manufacturers, later becoming one of the largest mattress companies in the United States and one of the most recognized names in the innerspring mattress category. The company's "Serta Counting Sheep" advertising mascots, a group of sleepy cartoon sheep introduced in a long-running early-2000s advertising campaign, became one of the most widely recognized mattress advertising icons, appearing in numerous commercials and building strong brand recognition tied specifically to sleep and comfort. Serta's 2012 corporate combination with rival Simmons Bedding Company under the same parent company created one of the largest bedding manufacturers in North America, consolidating two historically separate legacy mattress brands under shared corporate ownership while maintaining distinct retail branding. Serta's combination of its Depression-era manufacturer-cooperative origins and its widely recognized Counting Sheep advertising mascots has made it one of the most commercially significant traditional mattress brands in the country.
