The King Koil Modern Luxury mattress is a body-responsive coil and foam build sold as a curated sleep experience, listed at $1,499 for a queen. It pairs encased steel coils with memory foam, a TENCEL stretch surface and lavender-infused foam, and it carries a 10 year warranty. Buy it if you want a cradling, pressure-relieving feel with motion isolation in a traditional innerspring package. Skip it if you want a long home trial or a choice of firmness levels, since King Koil publishes no trial term or comfort options for this model; the Saatva Classic fixes both with a 365-night home trial and three comfort levels.

Who is the King Koil Modern Luxury for?
The King Koil Modern Luxury suits sleepers who want a cradling memory foam feel on top of a steel coil base, with the motion isolation that individually encased coils provide when a partner moves. It suits shoppers who like a TENCEL surface and lavender-infused foam, and who are comfortable buying a King Koil line at a single published queen price of $1,499. It is a good match for people who value craftsmanship and a traditional innerspring feel over a long trial window.
The construction reads as a classic comfort-plus-support stack. Memory foam contours gently for even pressure relief, coils and foams work together to reduce pressure points, and the encased coil system delivers full-body alignment with zoned stability. CertiPUR-US certification covers the foams for safety, durability and performance. If your priority is a mattress that cradles while still pushing back from below, this is the profile King Koil designed for.
It suits shoppers who already know King Koil and want a mid-menu line. Modern Luxury sits below PureBliss at $2,499 and Re-Spun at $2,899 in the brand’s published ladder, and above Scott Living at $1,299, so it occupies the entry point of King Koil’s premium tier.

What are the King Koil Modern Luxury specs?
The King Koil Modern Luxury is offered in six sizes, from Twin at 38 by 75 inches up to California King at 72 by 84 inches, with a queen listed at $1,499 and a 10 year warranty. The comfort layer uses memory foam with lavender infusion, the cover uses stretch TENCEL fibers, and the support core is an individually encased steel coil system. All foams are CertiPUR-US certified.

The dimensions matter if you are sizing a room. A king gives you 76 by 80 inches of surface, while a California King trades width for length at 72 by 84 inches. Our California King versus King comparison walks through that trade-off, and our queen versus king guide covers the step up from 60 by 80 inches.
How does the King Koil Modern Luxury feel?
The King Koil Modern Luxury feels cradling and pressure-relieving rather than firm and floating, because memory foam contours gently while the encased coil system pushes back underneath. King Koil describes cradling comfort, tailored pressure relief and consistent support as the three pillars of the build, with coils and foams working together to reduce pressure points. The brand publishes no firmness number for this model, so treat the feel as a medium, contouring innerspring rather than a numeric rating.
The surface adds its own character. Super stretch TENCEL fibers are described as ultra-soft and breathable, wicking moisture to keep you cool through the night, and the lavender-infused memory foam is presented as gently adapting to the body. King Koil says the individually encased coil system delivers personalized support and superior motion isolation, so a partner’s movement disturbs you less. For shoppers who prioritize that quality, our best mattresses for couples roundup places motion isolation at the center of the decision.
Because the foams contour and the coils are encased, the mattress should read as a balanced hybrid feel: sink at the surface, alignment from below. Shoppers who want a full hybrid menu across brands can look at our best hybrid mattresses selection.
What does the King Koil Modern Luxury cost and how do you buy it?
The King Koil Modern Luxury lists at $1,499 for a queen on the official King Koil product page, which is the only size price published for this line. The page carries both a retailer locator and an add-to-cart control, so the buying path is not limited to one channel. King Koil also notes free shipping and a 100-night trial on select online mattresses sitewide, which is a general site term rather than a trial confirmed for this specific model.
That distinction is worth holding onto. The confirmed terms for the Modern Luxury are the $1,499 queen price, the 10 year warranty, the six published sizes and the CertiPUR-US certified foams. The 100-night trial appears in the site-wide banner about select online mattresses, so confirm whether this model qualifies before you rely on it. King Koil runs frequent sales, so check today’s price before you buy.
For context on where $1,499 sits, King Koil’s published ladder runs Scott Living at $1,299, Modern Luxury at $1,499, PureBliss at $2,499, Re-Spun at $2,899, Natural and Intimate at $3,099 each, Xtended Life at $3,399, FLOWT at $3,999, and Reserve Luxury and SmartLife at $4,999. Modern Luxury is the second entry point in that menu. If you want the tech-forward end of the brand, our King Koil SmartLife review covers the body-sensing line at $4,999.

How does the King Koil Modern Luxury compare to the Saatva Classic?
The King Koil Modern Luxury and the Saatva Classic are both coil-based mattresses, but they publish different terms. The Modern Luxury lists at $1,499 for a queen with a 10 year warranty and no published firmness options, while the Saatva Classic lists at $2,229 for a king with a 365-night home trial, a lifetime warranty and three comfort levels: Plush Soft at 3/10, Luxury Firm at 5-7/10 and Firm at 8/10 on Saatva’s own scale where 1 is softest and 10 firmest.
| Term | King Koil Modern Luxury | Saatva Classic |
|---|---|---|
| Published price | $1,499 queen | $2,229 king |
| Warranty | 10 years | Lifetime |
| Trial | 100-night on select online mattresses, sitewide | 365-night home trial |
| Firmness choices | None published | Plush Soft, Luxury Firm, Firm |
| Delivery | Free shipping noted sitewide | Free white-glove delivery and setup, old mattress removal |
| Foam certification | CertiPUR-US |
The Saatva Classic is the stronger pick if trial length and firmness choice matter to you, because 365 nights beats the sitewide 100-night term and three comfort levels beat one published feel. The King Koil Modern Luxury is the more affordable entry at $1,499 for a queen, and it brings TENCEL and lavender-infused foam that the Saatva build does not use. Both are coil-forward designs with certified foams.
Who should NOT buy the King Koil Modern Luxury?
Skip the King Koil Modern Luxury if you need a long home trial, because King Koil publishes no trial term for this specific model and only notes a 100-night trial on select online mattresses sitewide. Also skip it if you want to choose your firmness, since no comfort levels are published for this line. The Saatva Classic fixes both gaps with a 365-night home trial and Plush Soft, Luxury Firm and Firm options.
Skip it if you want a natural or organic material story, because the Modern Luxury build is foam and steel coils with TENCEL and lavender infusion, not natural materials. King Koil’s Natural line, published at $3,099, is the brand’s answer to that preference. Skip it if you want a lifetime warranty, since the Modern Luxury carries 10 years and the Saatva Classic carries a lifetime warranty for the original purchaser.
Skip it if you want a firm, floating feel with no sink. The memory foam is described as contouring gently and cradling the body, so a stomach sleeper who wants to stay on top of the surface may find it too embracing. There is no firmer variant of this model to switch to.
What is the World Sleep Almanac score for the King Koil Modern Luxury?
World Sleep Almanac score: 7.4/10 for the King Koil Modern Luxury, an editorial rating based on the published terms below rather than a lab test. The score averages five criteria: price at $1,499 for a queen, a 10 year warranty, no published trial for this model, CertiPUR-US certified foams with TENCEL and lavender-infused memory foam, and free shipping noted sitewide with a retailer locator and add-to-cart on the product page.
- Price: 8/10. $1,499 for a queen sits below PureBliss at $2,499 and Re-Spun at $2,899 in King Koil’s published ladder.
- Trial and returns: 6/10. No trial term is published for this model; the sitewide banner notes 100 nights on select online mattresses.
- Warranty: 7/10. 10 years on every Modern Luxury mattress, shorter than the Saatva Classic lifetime warranty.
- Materials and construction: 8/10. CertiPUR-US certified foams, TENCEL cover, lavender-infused memory foam, encased steel coils.
- Delivery: 8/10. Free shipping noted sitewide, with both a retailer locator and an add-to-cart control on the product page.
The average of 8, 6, 7, 8 and 8 is 7.4. The score moves if King Koil publishes a trial term for this model or adds firmness options.
What is the verdict on the King Koil Modern Luxury?
The King Koil Modern Luxury is a solid buy at $1,499 for a queen if you want a cradling memory foam feel on encased steel coils with a 10 year warranty. It delivers TENCEL stretch, lavender-infused foam, CertiPUR-US certified materials and the motion isolation King Koil attributes to its individually encased coil system. It is the entry point of King Koil’s premium menu, sitting just above Scott Living at $1,299.
It is not the pick if you want a long trial or firmness choice, because neither is published for this model. In that case the Saatva Classic is the alternative that fixes it, with a 365-night home trial, three comfort levels and a lifetime warranty.

Frequently asked questions
Is the King Koil Modern Luxury a hybrid mattress?
The King Koil Modern Luxury combines memory foam with an individually encased steel coil system, which is the hybrid structure of foam comfort over coil support. King Koil describes the build as body-responsive coil systems with cool-touch, pressure-relieving materials, and the foams are CertiPUR-US certified.
Does the King Koil Modern Luxury sleep cool?
King Koil says the super stretch TENCEL fibers on the surface are breathable and help wick away moisture to keep you cool through the night. The brand makes that claim about the cover material; how cool any mattress feels depends on your room, bedding and body, so treat it as a material feature rather than a guarantee.
What sizes does the King Koil Modern Luxury come in?
The King Koil Modern Luxury is published in six sizes: Twin at 38 by 75 inches, Twin XL at 38 by 80 inches, Full at 54 by 75 inches, Queen at 60 by 80 inches, King at 76 by 80 inches and California King at 72 by 84 inches. Only the queen price of $1,499 is published for this line.
Does the King Koil Modern Luxury isolate motion?
King Koil says the individually encased coil system delivers personalized support and superior motion isolation, so you stay supported even when your partner moves. That is the brand’s claim about the encased coil design, and it is the feature to weigh if you share the bed.
How long is the warranty on the King Koil Modern Luxury?
Every King Koil Modern Luxury mattress carries a 10 year warranty. The exact model name is what goes on the quote and on the warranty, so keep it when you register the purchase.
