Our verdict

Earl Kluft effectively created the modern American luxury mattress category in the 1980s, and the Beyond Luxury Sublime is the current expression of that legacy — now produced under the Aireloom/E.S. Kluft umbrella in California. The build is unapologetically maximalist: a hand-tufted cashmere-blend cover, comfort layers of Joma wool, horsetail and natural latex, and a nested-coil support system with micro-coils above the primary pocket coils. The result is the plushest feel in this entire ultra-luxury group — closer to a European pillow-top grand-hotel bed than to the taut, springy Hästens or the buoyant Vispring. That plushness is the pitch and the warning: side sleepers and anyone who wants to sink into a mattress will prefer it to the Scandinavian and British competition, while back sleepers over 200 lb may find it too yielding. At roughly $9,000–$11,000 in King through retailers like Bloomingdale's, it is the most accessible of the true ultra-luxury tier — half the entry price of a Hästens 2000T setup — and frequent department-store promotions make the effective price lower still.

Mattress Construction

1

Hand-Tufted Cashmere-Blend Cover

Deeply tufted cover keeps the generous comfort layers from shifting

2

Joma Wool, Horsetail & Natural Latex

Natural cushioning layers provide plushness with more resilience than foam

3

Micro-Coil Comfort Layer

Thousands of miniature coils fine-tune surface contouring above the support unit

4

Nested Pocket Coil Support Core

Individually wrapped coils deliver deep support and strong edge structure

Sleep Position Analysis

Side Sleepers

The Kluft Beyond Luxury Sublime's softer feel (5/10) may provide more cushioning for side sleepers.

Back Sleepers

The Kluft Beyond Luxury Sublime's listed firmness of 5/10 may suit back sleepers seeking a medium-to-firm surface. Spinal alignment and hip support have not been objectively measured for this model unless documented test results appear above.

Stomach Sleepers

At 5/10 firmness, the Kluft Beyond Luxury Sublime may be too soft for stomach sleepers. Stomach sleepers may want to compare a firmer model, especially if they notice uncomfortable hip sinkage.

Combination Sleepers

The Kluft Beyond Luxury Sublime's hybrid construction provides responsive support that may make changing positions easier than with some slow-response all-foam designs. Pocketed coils can add responsiveness, but ease of movement varies with the comfort layers and the sleeper.

Which Kluft Beyond Luxury Sublime Model Should You Buy?

Kluft builds hand-tufted luxury mattresses in California using cashmere, silk, New Zealand wool and multiple hand-nested spring layers. The Beyond Luxury Sublime sits in the upper part of the range and is the model most often cross-shopped against European ultra-luxury at a fraction of their prices.

Hand-tufting versus quilting

Nearly every mattress you can buy has its comfort layers quilted to the cover by machine. Kluft hand-ties them through the full depth of the mattress with twine and rosettes, which is slower and considerably more expensive — and which stops the fill from shifting or thinning over years of use.

It's the single clearest visual marker of a genuinely traditional luxury build.

How the Sublime sleeps

Plush at the surface, around 5 out of 10, with the support arriving from the spring layers rather than from a firm foam base. Side sleepers get real shoulder and hip relief; back sleepers do fine because the springs hold the lumbar despite the soft top.

Temperature is neutral to cool. Cashmere, silk and New Zealand wool all move moisture, and there's minimal foam in the stack to store heat. Strict stomach sleepers should take the firmer Sublime build instead.

Why it's the value play in ultra-luxury

At roughly $8,999 for a queen, the Sublime uses a fill list comparable to European beds costing three to five times as much, made in California with US retailer support and a serviceable dealer network. If the goal is the materials and craftsmanship rather than a specific European brand, this is where the money goes furthest.

It also benefits from something the European brands don't offer: US luxury retailers discount around holidays. Buying a Kluft during a major sale event changes the value equation meaningfully, which is never the case with Hästens or Vispring.
