Kluft Royal Ascent can still make sense if you specifically want that brand, its retailer policy, or its lowest sale price. It is not our top buy-button recommendation. For most shoppers, we would compare it against Saatva Classic first, then use the cheaper options below if the budget is tighter.

Kluft Royal Ascent
7.8/10
- Genuinely premium materials: cashmere, alpaca, horsehair, natural Talalay latex, Belgian Damask cover
- Handcrafted in the USA with double-stitched edges, hand-tufted construction
- Nested pocketed coil system with micro-coil layer delivers responsive support and good motion isolation
- Breathable natural fiber stack sleeps cooler than most synthetic foam mattresses
- Price ($17,700+ queen) is 10x the cost of comparably performing hybrid mattresses
- No direct sleep trial from Kluft; trial depends entirely on the retailer (typically 120 nights)
- Only a 15-year limited warranty, shorter than the lifetime warranty offered by several competitors at a fraction of the price
- Multiple owner reviews cite sagging within 4 to 6 years, which undermines the value case at this price point
- Available only through select high-end retailers, not direct-to-consumer
The Royal Ascent delivers a genuinely exceptional sleep surface, and if you are comparing premium innerspring brands at the $15,000+ tier, it belongs in the conversation. For the other 99% of shoppers, the price-to-performance ratio is hard to justify when alternatives at under $2,000 match it on support and beat it on warranty and trial terms.
What is the Kluft Royal Ascent made of?
The Royal Ascent is a 15-inch luxury hybrid built entirely from natural and premium materials. Starting from the top:
- Cover: Belgian Jacquard Damask with silk and wool fiber filling, soft and cool to the touch.
- Comfort layers: Multiple tiers of cashmere, alpaca, New Zealand Joma wool, organic cotton, and horsehair. These fibers create the signature plush feel and regulate temperature through natural moisture-wicking.
- Latex layer: Natural Talalay latex provides responsive pressure relief with a buoyant feel distinct from memory foam.
- Micro-coil layer: A secondary tier of finely gauged micro-coils (approximately 19-gauge) adds responsiveness and prevents the latex from feeling too spongy.
- Support core: Original Marshall nested pocketed coils (approximately 15.5-gauge) form the base, with reinforced perimeter coils for edge support.
The entire construction is handcrafted, hand-tufted, and side-stitched. Each mattress is built individually, which is genuinely rare and part of what justifies the price to its target buyers. The mattress does not compress for shipping and must be delivered flat by a specialist retailer, which limits purchase options to select furniture and sleep showrooms.
Firmness and feel
The Royal Ascent is medium-plush in feel. The natural fiber layers and Talalay latex create deep cushioning without the slow sinking feel of memory foam. The underlying coil system keeps the surface responsive and bouncy, which most back and side sleepers find comfortable.
In our testing, the mattress is best suited to back sleepers and side sleepers under 230 lb. The plush comfort layer may not provide enough lumbar support for heavier sleepers or dedicated stomach sleepers, who typically need a firmer surface to maintain spinal alignment.
Cooling and breathability
The natural fiber stack, combined with the open-coil base, makes the Royal Ascent one of the better-performing mattresses for temperature regulation in our testing. Wool, cashmere, and cotton all wick moisture and allow air movement through the comfort layers. Hot sleepers who have struggled with synthetic foam mattresses typically find natural-fiber hybrids noticeably cooler.
Motion isolation
Motion isolation is moderate to good, better than older open-coil innerspring beds but not as effective as a pure memory foam mattress. The micro-coil layer absorbs some cross-mattress transfer, but couples with a very light sleeping partner may notice some movement, particularly when shifting positions.
Edge support
Edge support is strong. The reinforced perimeter coil system and hand-stitched border prevent rolloff and allow the full usable surface of the mattress to be used. This is a practical advantage for couples sharing a queen or king.
Durability concerns
This is the most significant concern raised by long-term owners. Multiple verified reviews report noticeable sagging or body impressions within four to six years of use. For a mattress priced above $17,000, this is a serious issue. Kluft's 15-year limited warranty covers defects, but the threshold for a valid sagging claim under most mattress warranties is typically 1.5 inches, which is well beyond the level most sleepers would find comfortable.
The durability gap between the Kluft's price and its longevity track record is a consistent theme in owner reviews over three or more years.
Trial and warranty
- Sleep trial: Kluft itself does not provide a direct sleep trial. Trial terms depend on the retailer: Mancini's Sleepworld, for example, offers a 120-night comfort guarantee if you also purchase a mattress protector. Other retailers may offer different terms or no trial at all.
- Warranty: 15-year limited warranty from Kluft, covering manufacturing defects and sagging above the warranty threshold. Foundation requirements apply: the mattress must be supported on a qualifying frame to keep the warranty valid.
- Delivery: Not sold direct. Delivery is through the retailer and typically includes white-glove setup at an additional cost or as part of the retailer's service.
Who should consider Kluft Royal Ascent?
The Royal Ascent makes sense for a narrow buyer profile:
- Shoppers who have already exhausted the $2,000 to $5,000 tier and want the absolute top of the market in natural materials.
- Side and back sleepers under 230 lb who strongly prefer a plush, responsive natural-fiber feel over foam.
- Buyers purchasing through a retailer with a strong comfort guarantee who want to try it risk-free for at least 90 nights.
Who should pass: Anyone prioritizing long-term value, shoppers who want a direct sleep trial or reliable warranty without retailer dependencies, heavier sleepers, and stomach sleepers.

How Kluft compares to accessible luxury alternatives
The comparison most relevant to Kluft buyers is not Kluft versus a $1,000 bed-in-a-box. It is Kluft versus other handcrafted or high-material-quality options in the $2,000 to $5,000 range, and whether a 10x price premium is justified.
For innerspring feel at a luxury tier, the Saatva Classic delivers comparable craftsmanship and a stronger buyer protection package. For natural latex specifically, PlushBeds Botanical Bliss offers GOTS-certified latex hybrid construction with a 25-year warranty at under $3,000.
If you are evaluating Kluft against a luxury mattress shortlist, it is worth reading those comparisons before committing to a five-figure purchase without a direct return option.
Frequently asked questions
Is the Kluft Royal Ascent worth the price?
For a narrow group of buyers who prioritize rare natural materials and handcrafted construction above all else, yes. For most shoppers, competing luxury hybrids at $2,000 to $4,000 match or exceed the Royal Ascent on sleep quality, warranty terms, and buyer protections at a fraction of the price.
Does Kluft offer a sleep trial?
Not directly. Kluft does not sell direct-to-consumer, so trial terms depend entirely on the retailer. Some authorized dealers offer 90 to 120 nights; others have strict no-return policies. Confirm trial terms with your specific retailer before purchase.
How long does the Kluft Royal Ascent last?
Kluft offers a 15-year limited warranty, but owner reviews suggest the mattress can begin showing body impressions within four to six years of daily use. This is a meaningful concern at this price tier.
What is the best alternative to Kluft for back pain?
Is the Kluft Royal Ascent compatible with adjustable bases?
Yes, the Royal Ascent is compatible with adjustable bed frames. Confirm with your retailer and follow Kluft's foundation requirements to keep the warranty valid.
