The global King Koil website identifies Avondale, Arizona, as the location of its worldwide headquarters and states that its mattresses are available in more than 80 countries.

1898 — The Beginning

King Koil’s story begins in St. Paul, Minnesota, where Samuel Bronstein established United States Bedding in 1898.

The original operation was extremely small: Bronstein began with just six employees in a small warehouse. The company gradually expanded its manufacturing capabilities and developed a reputation for innovation in mattress construction.1

This makes King Koil one of the older continuously recognized names in the American mattress industry.

1920s — Early Mattress Innovation

During the early decades of the company, United States Bedding began developing innovations in mattress construction.

King Koil’s own historical account notes a 1920 patent relating to a non-stretchable mattress and the introduction of coil springs into mattresses. Other historical material gives slightly different dates for individual patents, so the safest interpretation is that the company was actively developing spring and mattress-construction technology during this period.2

1930s — Birth of the King Koil Name

During the 1930s, United States Bedding developed an improved bedspring/mattress product and adopted the King Koil name.

This period is important because “King Koil” evolved from being a product name into the company’s principal international brand identity. The company’s historical accounts also associate this era with the introduction of the Koil Man, an early visual symbol of the brand.3

1960s–1980s — International Expansion

King Koil subsequently expanded beyond the United States. According to the brand’s historical timeline, international licensing began in Japan in the 1970s, followed by expansion into markets across Asia, Australia, Europe, Africa and South America during the following decade.

This international licensing model became an important part of King Koil’s business structure: rather than producing every mattress in a single centralized factory, the brand developed relationships with regional manufacturers and licensees.

A major part of King Koil’s identity is its emphasis on the relationship between mattress construction and bodily support. Historically, the company developed its brand around spring systems and mattress engineering. Over time, its products have incorporated different combinations of:

• Coil-spring systems
• Zoned support
• Foam
• Latex
• Comfort layers
• Quilted upholstery
• Specialized mattress fabrics
• Edge-support systems
• Adjustable-bed technology in selected markets

The exact technologies vary significantly between countries and collections because King Koil operates through regional manufacturing and licensing arrangements.

One of the most distinctive aspects of King Koil’s historical branding is its connection with chiropractic research and spinal support.

King Koil’s historical materials state that it collaborated with chiropractic specialists and the International Chiropractors Association (ICA) in developing mattresses intended to provide proper spinal alignment.4

This history helped establish a central theme in King Koil’s marketing: a mattress should provide not merely softness, but appropriate support for the body and spine. That distinction is important to understanding the brand. King Koil has traditionally positioned itself somewhere between luxury comfort and engineered orthopedic-style support, rather than simply competing on softness or visual luxury.

King Koil is somewhat different from a typical single-country mattress manufacturer. Its international business has historically relied heavily on licensing and regional manufacturing.

That means a King Koil mattress sold in one country is not necessarily manufactured in the same facility or according to exactly the same product lineup as a King Koil mattress sold in the United States. The global brand provides standards, technology, design concepts and brand identity, while regional companies can manufacture and distribute products for their respective markets.

This explains why King Koil collections, technologies, warranties and even product names can differ from one country to another.

Hospitality is an important part of King Koil’s business. The company supplies mattresses and bedding solutions to hotels, resorts and other hospitality properties. King Koil lists installations or relationships involving properties and groups such as JW Marriott, Mandarin Oriental, Banyan Tree, InterContinental, Westin, Hyatt, Accor and Aston, among others.5

This is strategically significant because hotel mattresses have different requirements from ordinary residential mattresses. Hotels typically need high durability, consistent comfort, high usage tolerance, reliable supply, replacement availability, custom specifications, fire and safety compliance, and consistent manufacturing quality. Consequently, King Koil has developed a substantial hospitality/B2B side in addition to its consumer retail business.

King Koil is primarily known for mattresses, but the brand has expanded into a broader sleep ecosystem.

Mattresses

The core category includes various types of innerspring mattresses, hybrid mattresses, foam-supported mattresses, luxury/premium mattresses, zoned-support mattresses, and hotel mattresses. The construction and naming differ by market.

Beds and Foundations

King Koil also offers bed bases and related furniture in some markets.

Pillows and Bedding

Depending on the country, the King Koil portfolio includes pillows, bolsters, quilts/duvets, mattress protectors, bed linen, and bed sets.

One of King Koil’s recurring areas of product development is the coil system. The basic idea behind zoning is relatively straightforward: different parts of the human body exert different amounts of pressure on a mattress. A zoned mattress therefore attempts to provide different levels of support across areas such as shoulders, back, hips, and legs. The goal is to balance pressure distribution and support rather than making the entire mattress uniformly firm.

In specific regional launches, such as the Indonesian market, King Koil introduced the Signature Gold Series in 2016 with a Gold Series Coil and 7-Zone Honeycomb Coil System. In 2022, it introduced the Auto Response Gold Coil and Auto-Zoning Body System within its Signature Collection.

King Koil’s positioning can be summarized as Premium comfort + engineered support + long heritage. It is not primarily positioned as a budget mattress manufacturer. Instead, the brand emphasizes:

• Heritage: More than a century of mattress-making history.
• Technology: Spring systems, zoning and material development.
• Comfort: A major component of its luxury/premium positioning.
• Support: Especially support associated with proper body and spinal alignment.
• Craftsmanship: Emphasis on materials, construction and skilled craftsmanship.
• Hospitality Credibility: Its presence in hotels and resorts reinforces its premium positioning.

From a brand-history perspective, several things distinguish King Koil:

1. Extremely Long History: The brand traces its origins to 1898, giving it more than 125 years of mattress-industry history.
2. Strong Association with Spring Mattresses: Coil technology has been central to King Koil’s development from its early history through modern product lines.
3. Spinal-Support Heritage: Its relationship with chiropractic organizations became an important component of its brand identity.
4. International Licensing: Rather than functioning simply as one centralized American mattress manufacturer, King Koil developed a large international network of licensees and regional manufacturers.
5. Strong Hospitality Presence: King Koil mattresses are used in hotels and resorts, giving the brand a second major business beyond consumer retail.

There is not necessarily one identical King Koil mattress range worldwide. Because the brand operates through regional licensees and manufacturers, the following can differ between countries:

• Mattress models
• Names
• Coil specifications
• Materials
• Firmness
• Dimensions
• Warranty
• Prices
• Retail channels
• Hotel products

Therefore, when evaluating a specific King Koil mattress, the country of sale and exact model matter considerably.

Today, King Koil presents itself as a global sleep brand rather than simply a traditional mattress manufacturer. Its U.S. operation describes the brand as manufacturing mattresses around the world while maintaining its American heritage, and states that King Koil products are available in more than 80 countries.6 Regional King Koil sources give slightly different figures—some currently say 90+ countries—which likely reflects differences in how licensees and markets are counted.

At its core, King Koil’s philosophy can be reduced to a simple proposition: sleep is not merely about having a soft place to lie down; a good mattress should combine comfort, support, materials and engineering to create better rest.

That philosophy explains why King Koil’s branding repeatedly connects luxury, craftsmanship, technology, comfort, and spinal/body support.
