The King Koil Reserve Luxury Premium is the brand’s handcrafted flagship, and it earns that position with materials you rarely see combined: hand-applied button tufting, natural Talalay latex, resilient horsehair and body-conforming memory foam, all sitting on a 3,000 glue-free encased coil system. King Koil lists the Reserve Luxury at $4,999 for a queen, which places it level with the SmartLife at the top of the brand’s published menu. If you want a mattress built around traditional upholstery craft rather than electronics, this is the King Koil to look at. If you want a Saatva instead, the Saatva Classic offers a 365-night home trial and a lifetime warranty at a lower list price, and it is the alternative we flag throughout this page.
King Koil publishes the Reserve Luxury with a 10 year warranty and lists the collection in Twin, Twin XL, Full, Queen, King and California King. The product page carries both a retailer search and a cart, so you can check availability in your size and see how King Koil handles the purchase where you live. The brand also runs a 100-night trial on select online mattresses, so confirm which terms apply to the Reserve Luxury at checkout.

Who is the King Koil Reserve Luxury Premium for?
The King Koil Reserve Luxury Premium suits sleepers who value traditional mattress craft and natural materials, and who are comfortable spending $4,999 for a queen. It is built for people who want hand-applied button tufting to hold the layers in place, Talalay latex for responsive comfort, horsehair for breathability and memory foam for body conformity, all supported by 3,000 glue-free encased steel coils. If that combination describes what you want from a luxury mattress, the Reserve Luxury is the King Koil model to consider.
It is less suited to shoppers working below the luxury tier. King Koil publishes lower entry points across its other lines, and the brand’s own collection descriptions separate the Reserve Luxury on handcrafted excellence from lines sold on foams, natural materials or body-sensing technology. If your budget or your priorities sit elsewhere, a different King Koil line, or the Saatva Classic with its dual-coil design and three comfort levels, will fit better.
What is the King Koil Reserve Luxury Premium made of?
The King Koil Reserve Luxury Premium layers natural Talalay latex, horsehair and memory foam, secured by hand-applied button tufting, over a 3,000 glue-free encased steel coil system. King Koil describes the tufting as a traditional technique that prevents layer shifting and preserves structural integrity. The coil count of 3,000 is the figure King Koil publishes for the Reserve Luxury collection, and the coils are glue-free and encased so each works independently.
Each material has a stated role. Talalay latex is listed as natural and resilient. Horsehair is described as a natural, breathable material that acts like a system of tiny springs, providing support and pliability while channeling away moisture and excess heat; King Koil states it is ethically and humanely acquired during grooming. Memory foam is listed as body conforming. Beneath those comfort layers, the coil system is credited with precise body contouring, pressure relief and edge support.
| Element | What King Koil publishes |
|---|---|
| Top construction | Hand-applied button tufting |
| Comfort materials | Natural Talalay latex, horsehair, memory foam |
| Support system | 3,000 glue-free encased steel coils |
| Warranty | 10 year warranty |
| Published queen price | $4,999 |
| Available sizes | Twin, Twin XL, Full, Queen, King, California King |
How does the Reserve Luxury feel to sleep on?
King Koil does not publish a firmness number for the Reserve Luxury. What the brand does publish is the material recipe: Talalay latex for responsive comfort, memory foam for body conformity, and horsehair for pliability, all held in place by hand-applied tufting. Together those materials describe a handcrafted, layered feel with cushioning on top and independent coil support underneath, rather than a single-foam or single-spring feel.
The 3,000 glue-free encased coils are described by King Koil as working independently to contour to the body, offering pressure relief and edge support. If you are comparing feels across King Koil lines, the brand positions the Reserve Luxury on handcrafted excellence, distinct from the Natural line sold on breathability and durability or the SmartLife line sold on patented body-sensing technology. For a broader look at how the brand’s models compare, our King Koil mattress reviews cover the collection side by side.
Shoppers comparing sizes should also weigh the trade-offs before committing at this price. Our California King versus King guide explains the dimension differences, and our queen versus King mattress guide covers when the larger footprint is worth it.
What sizes and dimensions does King Koil list?
King Koil lists the Reserve Luxury 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. The queen is the size King Koil publishes a price for, at $4,999. The other sizes are listed with dimensions on the product page, so confirm the quote for your size when you order.
Size choice matters at this price. A King gives you 76 by 80 inches of surface, while a California King trades width for length at 72 by 84 inches. If you are tall and sleep alone, the extra length may matter more; if you share the bed, the wider King is usually the more comfortable pick.

What do King Koil’s trial, warranty and delivery terms cover?
King Koil lists a 10 year warranty on every Reserve Luxury mattress. The brand’s site header advertises free shipping and a 100-night trial on select online mattresses, so confirm which of those terms apply to the Reserve Luxury when you order. The product page carries both a retailer search and a cart, so you can check how the purchase, delivery and trial are handled for your size and location.
For comparison, the Saatva Classic carries a 365-night home trial and a lifetime warranty, with free white-glove delivery that includes in-room setup and removal of your old mattress. Those terms are longer than the 10 year warranty King Koil publishes for the Reserve Luxury, and the trial window is longer than the 100 nights King Koil advertises for select online mattresses. If trial length and warranty coverage weigh heavily in your decision, that difference is worth factoring in.
How much does the King Koil Reserve Luxury Premium cost?
King Koil publishes $4,999 as the price for the Reserve Luxury in queen. That figure sits at the top of the brand’s published menu, level with the SmartLife and above lines such as FLOWT at $3,999, Xtended Life at $3,399, and Natural and Intimate at $3,099 each. The Reserve Luxury is priced as the handcrafted flagship, and the materials list explains the position: Talalay latex, horsehair, memory foam, hand-applied tufting and a 3,000-coil system.
Who should NOT buy the King Koil Reserve Luxury Premium?
The King Koil Reserve Luxury Premium is not the right pick if you want published firmness options, since King Koil describes the feel through materials rather than a numbered scale. It is also the wrong pick if you want a mattress sold purely online with a long trial and lifetime warranty, since King Koil lists a 10 year warranty for the Reserve Luxury and advertises its 100-night trial for select online mattresses. In those cases, the Saatva Classic is the alternative that fixes it: three published comfort levels, a 365-night home trial and a lifetime warranty.
It is also worth stepping down within King Koil if handcrafted natural materials are not your priority. The brand publishes lower price points across its other lines, and each collection is described on its own terms, from premium foams to body-sensing technology.
How does the Reserve Luxury compare to the Saatva Classic?
The King Koil Reserve Luxury Premium and the Saatva Classic are both premium innerspring mattresses, but they are built on different material philosophies. King Koil builds the Reserve Luxury around hand-applied button tufting, Talalay latex, horsehair and memory foam over 3,000 glue-free encased coils, and publishes $4,999 for a queen with a 10 year warranty. Saatva builds the Classic around a 3-inch Euro pillow top and a dual-coil design of triple-tempered recycled carbon steel, with over 1,000 coils in full size and up, and lists 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 is firmest.
The terms differ too. Saatva publishes a 365-night home trial and a lifetime warranty, with free white-glove delivery including in-room setup and old mattress removal. King Koil lists a 10 year warranty for the Reserve Luxury and advertises a 100-night trial on select online mattresses. If you want published firmness options and a longer trial and warranty, the Saatva Classic covers those bases; if you want handcrafted natural materials and a traditional tufted build, the Reserve Luxury is the pick.
| King Koil Reserve Luxury Premium | Saatva Classic | |
|---|---|---|
| Published queen price | $4,999 | List price published by size |
| Comfort options | – | Plush Soft 3/10, Luxury Firm 5-7/10, Firm 8/10 |
| Support system | 3,000 glue-free encased coils | Dual-coil, over 1,000 recycled carbon steel coils in full and up |
| Trial | 100-night trial advertised for select online mattresses | 365-night home trial |
| Warranty | 10 year warranty | Lifetime warranty |
| Delivery | Confirm at checkout | Free white-glove delivery with setup and old mattress removal |
World Sleep Almanac score: 7.4/10
The World Sleep Almanac editorial team scores the King Koil Reserve Luxury Premium at 7.4 out of 10, based on the criteria below. This is an editorial rating, not a lab test, and each sub-score follows from what King Koil publishes for this model.
- Materials and construction: 9/10. Hand-applied button tufting, natural Talalay latex, horsehair, memory foam and a 3,000 glue-free encased coil system make this the most traditionally handcrafted build King Koil publishes.
- Price: 6/10. At $4,999 for a queen, the Reserve Luxury sits at the top of King Koil’s published menu, level with the SmartLife and well above the brand’s other lines.
- Warranty: 6/10. King Koil lists a 10 year warranty, shorter than the lifetime warranty Saatva publishes for the Saatva Classic.
- Trial and delivery: 7/10. King Koil advertises a 100-night trial on select online mattresses and lists both a retailer search and a cart on the product page, so terms should be confirmed for your size.
- Size range: 9/10. Six sizes are published, from Twin through California King, with dimensions listed for each.
Verdict: the King Koil Reserve Luxury Premium is the brand’s handcrafted flagship, built on Talalay latex, horsehair, memory foam and a 3,000-coil system, and priced at $4,999 for a queen with a 10 year warranty. It suits shoppers who want traditional upholstery craft and natural materials. It is not the pick for tight budgets or for shoppers who want published firmness options and a long trial; the Saatva Classic is the alternative that covers those.

Frequently asked questions
Does the King Koil Reserve Luxury Premium come in a firmness choice?
The brand describes the feel through its materials: Talalay latex for responsive comfort, memory foam for body conformity and horsehair for pliability, held in place by hand-applied button tufting. If published firmness options matter to you, the Saatva Classic lists three: Plush Soft at 3/10, Luxury Firm at 5-7/10 and Firm at 8/10 on Saatva’s scale, where 1 is softest and 10 is firmest.
Is the horsehair in the Reserve Luxury ethically sourced?
King Koil states that the horsehair used in the Reserve Luxury is ethically and humanely acquired during grooming. The brand describes each hollow strand as channeling away moisture and excess heat, and acting like a system of tiny springs for support and pliability. It is one of the natural materials that distinguish the Reserve Luxury from King Koil’s foam-led lines.
How does the Reserve Luxury’s 3,000-coil system differ from other King Koil models?
The 3,000 glue-free encased steel coil system is what King Koil publishes for the Reserve Luxury collection, with each coil working independently to contour to the body. King Koil describes the result as precise contouring with pressure relief and edge support. Other King Koil lines use different constructions, and the brand separates them by description, from premium foams and advanced coil technology in Modern Luxury to patented body-sensing technology in SmartLife.
Can I buy the Reserve Luxury online?
King Koil’s product page for the Reserve Luxury carries both a retailer search and a cart, so you can check availability and terms for your size. The brand’s site header also advertises free shipping and a 100-night trial on select online mattresses, so confirm which terms apply to the Reserve Luxury at checkout. Our King Koil SmartLife review covers the brand’s other top-priced line if you want to compare before you buy.
