by The Beautyrest Black Ultra Plush is a high-end luxury hybrid aimed at side sleepers and light-weight combo sleepers who want deep, enveloping softness. Its BlackICE 4.0 cover, 2,000 nano coils, and multi-layer gel-infused memory foam deliver genuine pressure relief, but the very soft feel (roughly 3-4/10 firmness) makes it a poor fit for stomach sleepers and heavier sleepers who need more pushback. At $4,249-$5,799 it is a significant investment. If you want that same luxury-hotel feel at a lower price point, the Saatva Classic in Plush Soft is our top-rated alternative.

Beautyrest Black Ultra Plush: What You Need to Know
The Beautyrest Black Ultra Plush sits at the softest end of Simmons' premium Black line, a collection that targets the luxury hotel and department-store mattress buyer. It is a thick (16-18-inch) pocketed-coil hybrid with multiple comfort layers, including natural fiber blends, gel-infused memory foam, and Beautyrest's own nano-coil system directly beneath the cover. The target buyer is a side sleeper who wants to sink deeply into a mattress and wake without shoulder or hip pressure.
That's a narrow audience. Ultra-plush mattresses require a specific combination of body weight, sleep position, and personal preference to perform well. For everyone else, particularly back sleepers, stomach sleepers, and heavier sleepers, the mattress will feel too soft to keep the spine neutral overnight.
Construction and materials
Working from the top down, the Beautyrest Black Ultra Plush uses the following layers:
- BlackICE 4.0 Plant-Based Cover: A cooling-tech knit designed to draw heat away from the body on contact. Uses plant-derived Cool Technology fibers for moisture management.
- Alpaca, Cashmere, and Silk Comfort Layer: A natural fiber blend that contributes to the soft, plush surface feel and assists with temperature regulation.
- AirFeel Foam: A soft premium foam directly below the natural fiber layer, adding bounce and ventilation.
- SurfaceTouch Gel Memory Foam: Gel-infused memory foam that provides immediate pressure relief at the hips and shoulders, the most common complaint zones for side sleepers.
- AirCool Memory Foam: A proprietary conforming foam that adjusts to body shape and reduces pressure-point buildup.
- Self-Response Latex Layer: Natural latex provides light pushback and antimicrobial properties, preventing the mattress from feeling stuck or slow to recover.
- 2K Nano Coils: 2,000 individually operating nano coils (small, targeted springs) just above the main coil layer, adding micro-conformability and additional pressure distribution.
- T3 Pocketed Coil Technology: Beautyrest Black's triple-strand coil system forms the main support core. Each coil responds independently for motion isolation and targeted support.
- BeautyEdge Foam Perimeter: High-density edge foam encases the coil system to resist edge sag and maximize usable sleep surface.
All foam layers are CertiPUR-US certified. The mattress is manufactured in the United States.
Firmness and feel
The Beautyrest Black Ultra Plush lands at approximately 3-4 out of 10 on a standard firmness scale, placing it in the "ultra-soft" category. On contact, you feel a slow, enveloping sink as the natural fiber and gel memory foam layers contour around the body. The nano coils provide a secondary layer of gentle pushback before you reach the main coil base, which prevents the bottoming-out sensation that all-foam ultra-soft beds sometimes produce.
In practice this means:
- Side sleepers under 150 lbs: Excellent match. The mattress cradles the shoulder and hip without excessive sinkage.
- Side sleepers 150-200 lbs: Good match in most cases, depending on individual pressure sensitivity.
- Side sleepers over 200 lbs: Likely to sink past the comfort layers into the coil core, losing the pressure-relief benefit.
- Back sleepers: Generally too soft, particularly in the lumbar zone, where excess sinkage can reverse the natural spinal curve.
- Stomach sleepers: Not recommended. Ultra-soft surfaces allow the pelvis to drop, compressing lumbar discs overnight.
Cooling and breathability
The BlackICE 4.0 cover is Beautyrest's most advanced cooling textile, combining phase-change material and plant-derived fibers. The gel memory foam and nano-coil layers also help dissipate body heat more efficiently than conventional memory foam. The T3 pocketed coil base provides airflow channels throughout the support core.
Overall, the Ultra Plush runs cooler than a comparable all-foam bed in the same softness range. Sleepers who are prone to overheating generally report positive results, though the density of the comfort layers means it will not match a latex hybrid or open-coil system for raw airflow.
Motion isolation and edge support
The combination of memory foam comfort layers and individually wrapped pocketed coils produces strong motion isolation. Partners who move or get up at different times are unlikely to disturb each other, a major advantage for co-sleepers who prioritize undisturbed rest.
Edge support is handled by the BeautyEdge foam perimeter. The reinforced edge allows sitting on the side of the mattress without significant collapse, and the usable sleep surface extends close to the mattress perimeter. This is notably better than many foam-heavy beds in this softness range, which tend to have weak edges.
Durability
The Beautyrest Black series uses higher-density foams and triple-strand coils that hold up better than budget pocketed-coil constructions. Under normal use, expect 8-12 years before meaningful body impressions develop. The 10-year limited warranty covers manufacturing defects and body impressions greater than 1.5 inches.
One durability note: ultra-plush mattresses tend to develop impressions faster than firm models, because more body weight concentration occurs in softer comfort layers. Rotating the mattress head-to-foot every 3-6 months is recommended. The Beautyrest Black Ultra Plush is a one-sided design and cannot be flipped.

Pros and cons
- Exceptional pressure relief at shoulder and hip zones for lightweight side sleepers
- Natural fiber comfort layer (alpaca, cashmere, silk) adds genuine luxury feel
- 2,000 nano coils beneath the cover add micro-conformability not found on cheaper hybrids
- BlackICE 4.0 cover keeps surface temperature lower than standard memory foam
- Strong edge support from BeautyEdge perimeter for a bed this soft
- CertiPUR-US certified foams, made in the USA
- $4,249-$5,799 is very expensive for a 10-year warranty (vs. lifetime warranties on competing luxury brands)
- Ultra-soft feel suits only a narrow group: lightweight to average-weight side sleepers
- 100-night trial is shorter than competitors at this price tier
- One-sided design; cannot be flipped, and softness-related impressions may develop faster
- Back and stomach sleepers will not get adequate lumbar support at this firmness level
Who should buy the Beautyrest Black Ultra Plush
Buy it if: You sleep primarily on your side, weigh under 180 lbs, and want the most cushioned, hotel-luxury feel available. The natural fiber layers and nano-coil system genuinely elevate the comfort experience above standard memory foam beds, and the edge support is unusually strong for a mattress this soft.
Skip it if: You sleep on your back or stomach, weigh over 200 lbs, share the bed and need a firmer feel, or are working with any budget constraint. At this price, you are paying for the materials and brand heritage, but you are not getting an industry-leading trial window or warranty to go with it.
Better alternative: The Saatva Classic in Plush Soft delivers a comparable enveloping feel with a reinforced coil base that holds up better over time, a 365-night trial, and a lifetime warranty, all at roughly one-third the price.
The Beautyrest Black Ultra Plush is a genuinely impressive luxury mattress for the right sleeper: lightweight, side-sleeping, and willing to pay for natural-fiber comfort layers and advanced cooling technology. For most buyers, the Saatva Classic in Plush Soft covers the same need at a fraction of the cost, with a longer trial and better long-term warranty protection.
Frequently asked questions
Is the Beautyrest Black Ultra Plush good for back pain?
It depends on your sleep position and body weight. For lightweight side sleepers, the pressure relief at the hip and shoulder reduces the strain that often causes back tension. For back sleepers, the ultra-soft surface allows excessive lumbar sinkage, which can worsen lower back pain. A medium-firm mattress is generally more appropriate for back pain.
Can you use the Beautyrest Black Ultra Plush on an adjustable base?
Yes. The Beautyrest Black Ultra Plush is compatible with most adjustable bases. The pocketed-coil system flexes without permanent damage on articulating frames.
Is the Beautyrest Black Ultra Plush flippable?
No. It is a one-sided mattress with coils at the base and comfort layers on top. You can rotate it head-to-foot every 3-6 months to slow uneven wear, but flipping is not recommended.
How does the Beautyrest Black Ultra Plush compare to the Saatva Classic?
Both are luxury innerspring hybrids. The key differences: Beautyrest Black Ultra Plush is significantly softer (3-4/10 vs. 3/10 Plush Soft, 5/10 Luxury Firm, 7/10 Firm for Saatva), more expensive by a wide margin ($4,249-$5,799 vs. $1,095+ for Saatva), has a shorter trial (100 nights vs. 365 nights), and a shorter warranty (10 years vs. lifetime). The Saatva Classic offers more firmness options and much better long-term value.
What is the firmness rating of the Beautyrest Black Ultra Plush?
Approximately 3-4 out of 10 on a standard 1-10 firmness scale, making it one of the softer mainstream hybrid mattresses. Beautyrest classifies it as "Ultra Plush," which sits at the soft end of their lineup, below Plush and Pillow Top.
