Kluft Royal Ascent Plush Mattress Reviews (2026)

The Royal Ascent Plush succeeds because its softness has structure. The quilt and comfort layers ease pressure around the shoulders and hips, while the latex, microcoils, and nested support coils keep the body lifted. It also feels more breathable and easier to move on than a plush mattress dominated by slow memory foam. Buyers who want those qualities and care about hand-built materials will find a distinctive bed here. Everyone else can get strong pressure relief, edge support, and better purchase policies for far less money.

Who it suits

• Side sleepers who need substantial shoulder and hip cushioning without a deep, slow sink

• Back sleepers who like a plush top but still need steady support under the pelvis

• Couples who want a quiet coil system and a stable outer edge

Who should skip it

• Most strict stomach sleepers, especially those who carry more weight around the hips

• Anyone who wants a mattress that is easy to rotate or move

• Shoppers who need a generous direct-to-consumer trial or a value-focused upgrade

Over several weeks, the mattress was used for back and side sleeping, position changes, sitting near the perimeter, and sleeping close to the edge. The evaluation followed our broader mattress testing process, with repeated checks for support and alignment, pressure relief, motion transfer, surface temperature, responsiveness, and edge support. Firmness, weighted sink, temperature change, cross-bed vibration, and edge compression were measured under the same setup each time so the observations could be compared directly.

The plush top compresses in stages rather than giving way all at once. We rated the feel 4.5 out of 10 for firmness, and a 44-pound weight sank 2.1 inches at the center. On my back, the quilt filled the space below the waist without letting the pelvis drop sharply. On my side, the shoulder settled farther than the torso, which eased pressure without twisting the spine. Marcus found the surface warm but not stuffy, while Mia noticed the shoulder cushioning first and still felt well supported through her midsection.

The natural-fiber quilt and coil-heavy interior also provided good mattress breathability for a surface this plush. After 30 minutes of continuous contact, the surface temperature rose 5.0°F; 10 minutes after we got up, it was back within 1.4°F of its starting temperature. The bed remained responsive during position changes, although its springs leave more surface movement than dense foam. In three motion trials, a 10-pound ball dropped from 12 inches produced an average peak of 0.23 g at a sensor 24 inches away, with noticeable vibration lasting 1.2 seconds. Jenna and Ethan could feel larger turns but not every small adjustment.

The perimeter was another strength. Under a 200-pound simulated load, it compressed 3.1 inches compared with 3.7 inches at the center. Sitting directly on the edge still produced a soft initial dip, but the support underneath stopped the feeling of sliding outward. That stability makes more of the surface practical for two sleepers.

What we liked

• Deep shoulder and hip cushioning without the slow, trapped feeling common to softer foam beds

• A buoyant response that makes turning and getting out of bed relatively easy

• Perimeter support that remains dependable for sitting and sleeping near the edge

Who it is best for

• Side sleepers who want strong pressure relief with more lift than memory foam provides

• Back sleepers who prefer a soft surface over a supportive coil core

• Couples who regularly use the outer third of the mattress

Where it falls short

• Stomach sleepers who need a flatter, firmer surface under the hips

• Anyone whose bed frame, sheets, or mobility needs are poorly suited to a tall mattress

• Buyers who prioritize a long universal trial, straightforward online returns, or value

• Mattress type: Luxury innerspring with latex, specialty microcoils, and nested pocketed coils.

• Feel: Plush; about 4.5 out of 10 in our firmness evaluation.

• Profile: 14.5 inches by Kluft’s specification; often rounded to 15 inches by retailers.

• Quilt: Belgian Jacquard damask, silk/wool and wool/alpaca fibers, FR knit, zoned TerraPur latex, convoluted foam, and stretch-knit backing.

• Comfort system: 19-gauge microcoils (1,872 in Queen; 2,400 in King), multiple TerraPur natural-latex layers, wool/cashmere, organic cotton, and horsehair.

• Support system: High-density encased perimeter and an Original Marshall nested calico pocketed-coil unit in 15.5 gauge.

• Edge support: Reinforced high-density perimeter.

• Adjustable-base compatibility: Yes; it fits the use case covered in our adjustable-bed mattress guide.

• Sizes: Twin, Twin XL, Full, Queen, King, California King, and Split California King, depending on the retailer.

• Matching foundation: Eight-way hand-tied construction in 5.75- or 9-inch profiles.

• Price: Retailer-dependent. Current listings found during review start around $15,997, with one authorized seller listing Queen near $18,000 and King or California King near $22,500 before promotions.

• Availability: Sold through authorized retailers, with showroom access and delivery terms varying by location. It is not compressed and shipped as a mattress in a box.

• Comfort exchange: Retailer-specific. One current authorized seller offers 120 nights, extended to 365 nights with a qualifying protector purchase.

• Warranty: Kluft’s current registration page states a 10-year manufacturer guarantee. Some retailer listings and law-label codes show longer terms, so confirm the exact warranty code before buying.

Choose it if you want a plush mattress that remains buoyant and supportive, and if natural fibers, latex, hand-tufting, and nested coils matter enough to justify the price. It is best matched to side sleepers, back sleepers who enjoy a soft top, and couples who need usable edge space. Check your finished bed height, fitted-sheet depth, delivery route, retailer exchange policy, and law-label warranty before placing an order.

If pressure relief matters more than rare materials, the Helix Midnight Luxe offers a medium, side-sleeper-friendly hybrid at a small fraction of the price. The Saatva Classic is the more practical choice for shoppers who want selectable firmness, in-room setup, a 365-night trial, and a traditional dual-coil feel.

The soft surface allows more hip sink than most strict stomach sleepers need, especially at higher body weights. At 14.5 inches tall, the mattress also requires deep-pocket sheets and can create an awkward finished bed height on a thick foundation. Its weight makes rotation a two-person job, while the retailer-based trial and exchange terms are less uniform than the policies offered by major direct-to-consumer brands. Above all, the price is difficult to justify unless the specific combination of handwork, natural fibers, latex, microcoils, and nested coils is the reason you are buying.

Why these alternatives belong on the shortlist

• Each offers a plush or pressure-relieving option with a supportive coil system.

• All cost substantially less than the Royal Ascent Plush at current prices.

• They provide clearer purchase policies or broader retail access.

Aireloom Luxetop M2 Plush is the closest construction match. It combines TerraPur latex, cotton, dual microcoil layers, and a plush handmade design. Its feel is similarly enveloping and responsive, but its official Queen price starts around $8,000—still less than half the Royal Ascent’s current Queen price.

Stearns & Foster Reserve has a more familiar luxury-retail footprint and a lower starting price near $4,800 for a Queen before promotions. Its TEMPUR-Indulge foam and cool-to-the-touch cover create a closer, more foam-shaped contour than the Kluft, while the dense coil system and reinforced edge retain an innerspring foundation.

The Helix Midnight Luxe is the convenience pick. It is a 13.5-inch boxed hybrid with zoned lumbar support, a medium feel, and optional cooling upgrades. It lacks the Royal Ascent’s natural-fiber stack and handcrafted presentation, but it is far easier to buy, test at home, return, and move.

The Saatva Classic offers the strongest balance of traditional spring feel and buyer-friendly service. It comes in three firmness levels and two heights, includes in-room setup, and carries a 365-night home trial. It feels less deeply upholstered than the Kluft, but shoppers who are unsure about committing to one very plush feel get more flexibility.

• Use a rigid, properly supported foundation; excess flex beneath the mattress makes the plush top feel less controlled.

• Measure the combined mattress and foundation height before delivery, especially if getting in and out of a tall bed is difficult.

• Check fitted-sheet pocket depth before buying. A nominal 15-inch sheet may not leave enough room once a protector is added.

• Side sleepers can place a pillow between the knees to keep the hips stacked as the shoulders settle into the surface.

• Use breathable sheets and a thin protector rather than a thick foam topper that masks the feel and holds more heat.

• Follow Kluft’s care instructions and rotate the mattress with two people; do not flip a one-sided design.

• When trying it in a showroom, spend at least 10 minutes in your normal sleep position and another few minutes near the edge.

• Ask the retailer to put the comfort-exchange terms, delivery charges, and haul-away service in writing.

• Protect the quilt from the first night without adding a thick layer that changes the pressure relief.
