Explore NowKing Koil Mattresses — Over 125 Years of Handcrafted Sleep
King Koil is one of the oldest mattress brands in the United States — and one of the few that has used its history as a foundation for genuine innovation rather than just a marketing claim. Founded in 1898 and still manufacturing in the United States today, King Koil has spent more than a century refining what a well-built mattress should feel like. The result is a lineup of handcrafted mattresses built around purposeful design, premium materials, and the kind of sleep quality that shows up in how you feel every morning.
RC Willey carries King Koil mattresses across a range of collections and comfort levels. Browse King Koil at RC Willey and find the mattress that fits the way you sleep.
The King Koil Story
In 1898, Samuel Bronstein founded United States Bedding in St. Paul, Minnesota — starting with six employees in a small factory and a straightforward ambition: build a better bed. What followed was more than a century of steady growth, product innovation, and a commitment to quality that outlasted every shift in the mattress industry around it.
The King Koil name itself has an interesting origin. During the 1930s, the company was looking for a new name to go with a significantly improved bedspring design. They held a naming contest — and the winning entry, submitted by a thirteen-year-old girl named Erla Bell Thompson, became the brand identity that's been on the side of American mattresses ever since.
Through the mid-20th century, King Koil pioneered a manufacturing licensee model that allowed the brand to expand globally while maintaining local craftsmanship. Independent manufacturers in markets around the world produced King Koil mattresses to the brand's exacting standards — an approach that helped King Koil grow into one of the most recognized mattress names across more than 80 countries.
In recent years, King Koil has undergone a significant transformation in the United States. The brand shifted deliberately from the promotional price segment into the premium and ultra-premium market, opening a state-of-the-art manufacturing facility in Avondale, Arizona, and refocusing the lineup around handcrafted construction, advanced materials, and long-term sleep performance. Today, King Koil is recognized as a premium American mattress manufacturer with global reach and a product lineup built around comfort, wellness, and durability.
Where Are King Koil Mattresses Manufactured?
King Koil's primary U.S. manufacturing facility is located in Avondale, Arizona, where the company's headquarters are also based. The Avondale facility serves seventeen western states and is where King Koil's premium and ultra-premium collections are handcrafted. Eastern U.S. distribution is managed through a strategic manufacturing partnership that allows King Koil to serve the full country efficiently while maintaining consistent production standards.
Internationally, King Koil operates through a network of licensed manufacturers across more than 80 countries. Each licensee produces King Koil mattresses according to the brand's quality specifications and has access to King Koil's proprietary coil systems and material technologies. This global-local model is central to how King Koil delivers consistent quality across vastly different markets while staying connected to the specific needs of local consumers.
Why Buy a King Koil Mattress
More than 125 years of mattress craftsmanship. King Koil doesn't borrow credibility from marketing — it earns it from history. The brand has been refining mattress construction since 1898, and that accumulated knowledge shows up in the precision of the coil systems, the quality of the comfort layers, and the durability of the finished product.
Handcrafted construction at every level. King Koil mattresses are assembled by skilled artisans — not manufactured purely by machine. Each layer is placed with intention, each tuft and stitch is part of a deliberate construction process. The result is a mattress that holds its shape, support, and feel significantly longer than mass-produced alternatives.
Premium materials from surface to core. King Koil uses materials chosen for performance and longevity rather than cost minimization. Tencel fabric covers, Talalay latex comfort layers, Joma wool, high-density foams, and advanced pocketed coil systems are all part of the King Koil material story — each component selected to contribute meaningfully to sleep quality.
International Chiropractors Association recognition. King Koil has a longstanding relationship with the International Chiropractors Association, and many King Koil mattresses carry ICA recognition for spinal support and back health. For shoppers who prioritize sleep posture and spinal alignment — particularly those with back issues or chronic discomfort — this is a meaningful differentiator.
A premium lineup at accessible price points. King Koil's premium positioning doesn't mean inaccessible pricing. The brand delivers handcrafted quality and advanced materials at price points that make genuine sleep quality achievable for a wide range of shoppers rather than a narrow luxury segment.
What Are the Different Types of King Koil Mattresses?
King Koil's current lineup is built around several distinct collections, each designed for a specific sleep experience and price tier.
King Koil SmartLife
The SmartLife collection is King Koil's most technologically advanced mattress line. It uses patented body-sensing technology and adaptive support systems that respond to the sleeper's body in real time — adjusting support and pressure relief throughout the night to maintain consistent spinal alignment and comfort across position changes. SmartLife is built for sleepers who want more than a static foam or coil system and are willing to invest in a mattress that actively works to improve sleep quality.
King Koil Xtended Life
The Xtended Life collection is built around durability — premium materials and purposeful construction designed to deliver consistent performance over an extended product lifespan. For shoppers who want a mattress that holds its support and comfort for years rather than compressing and degrading within the first few seasons, Xtended Life delivers on that promise through higher-density foams, reinforced edge support, and coil systems engineered for long-term resilience.
King Koil Intimate Handcrafted
The Intimate collection is King Koil's most traditionally crafted line — a hand-tufted, classically constructed mattress that combines old-world craftsmanship with modern comfort engineering. Hand tufting pulls the mattress layers together at regular intervals, keeping the fill evenly distributed and maintaining the mattress's profile and support over time. The Intimate collection is a strong choice for shoppers who appreciate traditional mattress construction and want a sleep surface that feels as considered as it looks.
King Koil iBed
The iBed collection focuses on comfort-forward design — materials chosen specifically for pressure relief, temperature regulation, and all-night comfort. iBed mattresses use layered foam and pocketed coil systems to deliver a surface that cradles the body at pressure points while providing enough underlying support to keep the spine properly aligned. The collection is particularly well suited to side sleepers and couples with different comfort preferences.
What Materials Are Used in King Koil Mattresses?
King Koil's premium positioning is supported by a commitment to materials that perform at a higher level than standard mattress components. Here's what goes into a King Koil mattress.
Pocketed Coil Systems
Pocketed coils — also called individually wrapped or encased coils — are the primary support system in most King Koil mattresses. Each coil moves independently rather than as part of a connected grid, which allows the system to conform to the body's shape and respond to individual pressure points without transferring motion across the mattress. This construction is particularly valuable for couples — one partner's movement has minimal impact on the other side. King Koil's coil systems are engineered for both responsiveness and durability, with coil counts and gauges selected to match each collection's performance goals.
Talalay Latex
Talalay latex is one of the more refined comfort materials available in mattress construction. The Talalay process produces a more consistent, open-cell latex structure than the Dunlop process, resulting in a feel that's buoyant and responsive without the dense, slow-recovering quality of memory foam. Talalay latex provides excellent pressure relief, naturally resists dust mites and allergens, and maintains its performance significantly longer than most synthetic foam alternatives.
Tencel Fabric
Tencel is a sustainable, plant-derived fiber used in King Koil's cover fabrics and comfort layers. It's naturally moisture-wicking and temperature-regulating — moving perspiration away from the sleep surface and helping maintain a comfortable sleeping temperature throughout the night. Tencel is also softer than most synthetic cover fabrics, which contributes to the surface feel that distinguishes a King Koil mattress from the first night.
Joma Wool
Joma Wool is a premium natural wool used in select King Koil collections as a comfort and temperature-regulation layer. Wool's natural properties make it one of the most effective temperature-regulating materials available in mattress construction — it absorbs moisture when the body is warm and releases it as temperatures cool, helping keep the sleep surface comfortable across seasonal and nightly temperature variations.
High-Density Foams
High-density foams in King Koil mattresses serve both as comfort layers and as transition layers between the coil support system and the surface. Higher foam density means greater durability — the foam holds its shape and support longer under sustained compression than lower-density alternatives that compress and lose their effectiveness within a few years of regular use.
What Are the Prices of King Koil Mattresses?
King Koil sits in the premium mattress segment, with pricing that reflects handcrafted construction, advanced materials, and the durability that comes from both. Entry-level King Koil collections offer premium quality at accessible price points for shoppers moving into the brand for the first time. Mid-range and upper collections — including SmartLife and Intimate Handcrafted — reflect the full investment in materials and craftsmanship that define King Koil's positioning in the premium and ultra-premium market.
RC Willey carries King Koil mattresses across the collection range with financing options available to help spread the cost of a premium mattress comfortably over time. A well-built mattress is a long-term investment — and King Koil's combination of durable construction and premium materials means the value compounds over years of better sleep rather than degrading after the first season.

Who Is King Koil Best For?
King Koil is a particularly strong match for several types of shoppers.
Shoppers ready to invest in long-term sleep quality. King Koil is built for people who understand that a mattress is something you use every night for a decade or more — and that what you spend on that investment shows up in how you feel every morning. The brand's premium materials and handcrafted construction are designed for the long run, not the short-term impression.
Back health-conscious sleepers. King Koil's relationship with the International Chiropractors Association and its focus on spinal support make it a strong choice for shoppers who manage back issues or prioritize sleep posture as part of their overall wellness approach.
Couples with different comfort needs. The pocketed coil systems in most King Koil mattresses provide strong motion isolation — each coil moves independently, so one partner's movement doesn't disturb the other. Combined with comfort layers that respond to individual body weight and shape, King Koil works well for couples who don't sleep identically.
Sleepers who prioritize natural and sustainable materials. Tencel, Talalay latex, and Joma Wool are all materials chosen with environmental consideration alongside performance. For shoppers who want premium sleep quality without synthetic materials throughout, King Koil's natural-material focus is a meaningful differentiator.
A Few Things Worth Knowing About King Koil
- Does King Koil offer a warranty? King Koil mattresses come with manufacturer warranty coverage. Specific terms vary by collection — reviewing the warranty details for your chosen model before purchasing is always worthwhile. RC Willey also offers extended protection options at the time of purchase.
- How long should a King Koil mattress last? With proper care and a supportive foundation, a King Koil mattress in the mid-range and above can comfortably last ten or more years. The Xtended Life collection is specifically engineered for above-average durability, and the handcrafted construction across all collections contributes to longer-than-average product life compared to mass-produced alternatives.
- Do I need a specific foundation for a King Koil mattress? King Koil mattresses work on a variety of support systems — platform bases with slats, adjustable bases, box springs, and solid foundations. Slat spacing should not exceed three inches to provide adequate support for foam and hybrid constructions. Check the specific collection's guidelines for foundation compatibility before purchasing.
- Are King Koil mattresses good for hot sleepers? Yes — particularly collections that incorporate Tencel fabric covers, Talalay latex, and Joma Wool, all of which actively support temperature regulation. The open-cell structure of Talalay latex allows airflow through the comfort layer, and Tencel and wool both move moisture away from the sleep surface. For hot sleepers, selecting a King Koil collection that features these materials specifically is the most effective approach.
- Can I try a King Koil mattress before buying? Yes — visiting an RC Willey showroom is the best way to experience a King Koil mattress in person before committing. Testing a mattress in your actual sleep position for several minutes gives you a much more reliable sense of how it'll feel night after night than any online description can provide.
- Is King Koil available in all standard mattress sizes? Yes. King Koil mattresses are available in twin, twin XL, full, queen, king, and California king sizes across the main collections. Size availability may vary by collection — checking current RC Willey inventory confirms what's in stock in your preferred size.
