Sharing a bed with a partner who prefers a completely different mattress firmness is one of the most common, and most overlooked, sources of household compromise. Sleep Number built its entire business around solving exactly that problem, letting each side of the bed be adjusted independently at the touch of a button. Here’s a full breakdown of Sleep Number’s history, how the technology works, and whether it’s worth the investment.
What Is Sleep Number?
Sleep Number Corporation is an American mattress manufacturer and retailer founded in 1987 by Robert “Bob” Walker and his wife JoAnn Walker, originally under the name Select Comfort, and headquartered in Minneapolis, Minnesota. Bob Walker had previously worked at Comfortaire Corporation, the company credited with inventing the adjustable air-supported sleep system category in 1980, and he brought that foundational technology knowledge with him when he and JoAnn launched their own company.
The company acquired Comfortaire Corporation itself in January 2013, bringing the original innovator of adjustable air-bed technology under the same corporate roof, before closing that third-party retail business in 2017. In November 2017, Select Comfort Corporation officially changed its name to Sleep Number Corporation, aligning the company’s formal identity with the branded product that had defined its business for decades. Today, Sleep Number is a publicly traded company on Nasdaq under the ticker SNBR, operating around 600 stores across the US as of December 2025, with manufacturing and distribution facilities in Minnesota, South Carolina, and Utah.
How Does the Sleep Number Bed Work?
The core of Sleep Number’s product is its patented adjustable air chamber technology, which allows each side of the mattress to be independently firmed or softened using a remote or connected app. A “Sleep Number” itself refers to a personalized setting between 0 and 100, representing the ideal combination of comfort, firmness, and support for an individual sleeper, a scale the company recommends testing by starting at the firmest setting (100) and gradually adjusting downward until you find your comfortable point. Because each side of the bed operates independently, this technology is particularly well suited for couples with different firmness preferences, letting one partner sleep on a notably firmer or softer setting than the other on the very same mattress.
What Makes Sleep Number Different?
- Independently adjustable comfort per side — the brand’s signature air chamber technology lets each sleeper customize their own side of the mattress, addressing a genuinely common issue for couples
- SleepIQ technology — select Sleep Number beds include SleepIQ, a sleep tracking system that monitors sleep quality and provides data-driven feedback and adjustments over time
- ComfortMode adaptability — Sleep Number’s ComfortMode feature is designed to adapt to a sleeper’s changing needs and life circumstances, rather than locking in a single fixed setting forever
- Long-standing warranty coverage — Sleep Number backs its mattresses with a lengthy limited warranty, historically covering defects for up to 25 years from the original purchase date, reflecting genuine confidence in long-term durability
- In-person, professional-guided shopping — Sleep Number operates its own retail stores staffed by Sleep Professionals, offering a hands-on, guided shopping experience rather than a purely online, unassisted purchase

Is Sleep Number Good Quality?
Sleep Number has built nearly four decades of credibility around its adjustable air chamber technology, a category the company’s founder had direct, foundational experience with prior to launching the business. The brand’s long-standing, generous warranty coverage, historically up to 25 years on materials and workmanship defects, reflects real confidence in the durability of its air chamber system specifically, even as customer feedback on the broader product experience has been more mixed.
Customer reviews of Sleep Number generally reflect a positive-but-nuanced picture: many sleepers, especially couples with differing firmness preferences, praise the genuine value of independently adjustable comfort and appreciate the brand’s customer service and in-store guidance. At the same time, some reviews note trade-offs including a higher price point compared to standard mattresses and occasional feedback around edge support and long-term durability of specific components. As with any premium adjustable bed system, it’s worth testing the product in person at a Sleep Number store before committing to a specific model and price tier.
Sleep Number’s Price-Match Guarantee
Sleep Number offers a price-match commitment for recent purchases: if an eligible Sleep Number sale drops the price on select purchases within 30 days of your original purchase, the company states it will match the difference. This kind of post-purchase price protection is a meaningful, practical benefit worth knowing about before buying, particularly since mattress pricing and promotions can shift relatively often.

Tips for Buying Sleep Number
- Visit a store in person to work with a Sleep Professional and properly test different Sleep Number settings before purchasing
- Take advantage of independent side adjustment if you’re shopping as a couple with different firmness preferences, since this is the brand’s core differentiator
- Consider SleepIQ-equipped models if you want ongoing sleep tracking and data-driven feedback over time
- Ask about the price-match policy if you’re comparing timing around a potential upcoming sale

Final Verdict: Is Sleep Number Worth It?
Sleep Number has spent nearly four decades refining a genuinely useful piece of sleep technology: a mattress that lets two people with completely different firmness preferences share the same bed comfortably. With patented adjustable air chamber technology, optional sleep tracking through SleepIQ, and a long-standing warranty reflecting real confidence in durability, Sleep Number offers meaningful value for couples and individuals who want precise, adjustable comfort. For anyone tired of compromising on mattress firmness, Sleep Number is well worth testing in person at one of the brand’s stores.
