Beautyrest Black Series Five XCS Plush: a deep plush bed built not to sleep hot
Soft beds almost always come with a tax: the foam you sink into is the foam that traps your heat. The Beautyrest Black Hybrid Series Five XCS in Plush is the model engineered to refuse that trade. It's the flagship of the XCS line, a 3-out-of-10 plush at 15 inches, built around Beautyrest's most aggressive cooling and the most micro coils in the line. If you've wanted to settle into a deep, cradling bed but kept backing away from soft mattresses because they sleep warm, this is the one made to fix exactly that.
The cooling is the headline
XCS leads with temperature. A cool-to-the-touch Sleep Climate Surface sits over Micro Diamond Memory Foam treated with BlackICE Max, Beautyrest's most advanced cooling system, placed on the first deeply-cradling layer, right where your body sinks in and a plush bed would otherwise hold warmth. The payoff is 30% more cooling power and body heat moved up to twice as long as a non-XCS Beautyrest Black hybrid. No mattress is air conditioning, but this is real engineering against heat, aimed at the precise spot soft beds get wrong.
Support, layer by layer
Under the cooling comfort layers, the Series Five rides on 4K Micro Coils, two stacked 2K layers, over a Triple-Stranded Pocketed Coil core with a high-density foam encasement. Each core coil is twisted from three strands of steel and sealed in its own pocket: point-by-point support and the most advanced motion separation in the Black line. The 4K Micro Coils give the deepest, most instant contour Beautyrest builds, and they're the only thing separating this flagship from the rest of the ladder. The encasement reinforces the perimeter for the strongest edge in the line.
Who it suits, and who it doesn't
This is the Plush, a 3 out of 10: a deep cushion for the shoulder and hip with coils underneath keeping a soft bed from sagging. Lying on it, you feel a slow, enveloping settle while the coils still hold your spine in line. It's aimed first at side sleepers, where those pressure points carry the load and a softer surface lets them sink while the spine stays straight. Back sleepers who genuinely prefer soft are well served too. It's not the first pick for stomach sleepers or many heavier sleepers, who tend to want a flatter, firmer plane. If that's you, the firm or medium XCS is the smarter feel, and the floor will point you to it rather than the priciest box.
Living with it over time
For couples, the wrapped coils are what you notice every night: each moves on its own, and a partner climbing in late barely registers across the bed. The reinforced edge gives you a confident perimeter to sit on and the full width to sleep on. It runs on a compatible adjustable base, and comes in Split Head Queen and Split Head King so each person can adjust their own head section without splitting the sleep surface. The foams are CertiPUR-US certified.
Where it sits in the line
The XCS ladder climbs from the Series Three Plush (the same soft instinct on simpler hardware) through the Series Four Medium up to this Series Five, gaining finer contour and a stronger edge as you climb. See the whole wall in the full Beautyrest collection, and if you're cross-shopping premium hybrids, the honest Stearns & Foster comparison lays it out without spin.
Ten minutes beats ten reviews
Deep cooling and deep contour are both feels you confirm lying down, not reading specs. The Series Five XCS Plush is on the floor with the rest of the Beautyrest Black line across all five Kentucky showrooms (Lexington on Nicholasville Road, Georgetown, Somerset, London, and Richmond, no appointment needed), so you can test the cool surface and the plush settle on your side, the way you actually sleep. Select your size to see the live price and add it to your cart, or come lie on it this week. You get the 100-night trial and Beautyrest's 10-year warranty, honored because Mattress Overstock is an authorized dealer; if it isn't right, you exchange it for store credit toward a bed of equal or greater value. Free local delivery, the old mattress hauled away, and everyone on the floor is paid the same no matter which brand you choose. Mattress Overstock has been independent and Kentucky-based since 2012, rated about 4.7 stars across 535 Google reviews.
What makes this mattress different
BlackICE™ Max Cooling, 30% More Cooling Power
Beautyrest's most aggressive cooling sits on the first memory foam layer, the spot a plush bed usually traps heat: 30% more cooling power, moving body heat up to twice as long.
Cool-to-the-Touch Sleep Climate™ Surface
The cover reads cool the second you lie down, then BlackICE™ Max keeps pulling heat through the night. The coolest surface in the Beautyrest Black hybrid range.
4K Micro Coils, the Most in the Line
Two stacked 2K micro-coil layers (4,000 total) give the deepest, most instant contour at the shoulder and hip, then spring back the moment you move. No other XCS model carries this layer.
Triple-Stranded Pocketed Coil® Core
Each coil is twisted from three strands of steel and sealed in its own pocket: point-by-point support and Beautyrest Black's most advanced motion separation, so a restless partner stays on their side.
Plush Feel, 3 out of 10
Tuned soft for the side sleeper who wants to sink into deep cushion at the shoulder and hip without the bed sagging underneath.
High-Density Foam Encasement, Enhanced Edge
FORM™ HD and FORM™ HD Max foams contour close, and a high-density encasement reinforces the perimeter so the plush holds firm where you sit and sleep wide.
Split-Head Sizing, Adjustable-Base Ready
The ContourCover™ enables Split Head Queen and Split Head King for independent head adjustment without splitting the sleep surface. Works on a flat foundation or a compatible adjustable base.
100-Night Trial, 10-Year Warranty, Free KY Delivery
A 100-night trial and Beautyrest's 10-year limited warranty, honored because you buy from an authorized dealer. Free local delivery, and the old mattress leaves with the crew.
Series Five XCS Plush, layer by layer
The flagship XCS stacks deep cooling comfort over the most layered coil system in the line, top to bottom:
- Cool-to-the-touch Sleep Climate™ Surface. The cover starts cool the instant you lie down.
- ContourCover™ with BlackICE™ Max memory foam. Cooling is applied to this first deeply-cradling layer for 30% more cooling power and to move body heat up to twice as long, exactly where a plush bed would otherwise hold warmth.
- FORM™ HD Max + FORM™ HD Material. High-density comfort foams that envelop every curve for flagship pressure relief with freedom of movement.
- 4K Micro Coils (two stacked 2K layers). The deepest, most responsive contour layer Beautyrest builds, and the only XCS model that carries it.
- Triple-Stranded Pocketed Coil® core with High-Density Foam Encasement. Point-by-point support, Beautyrest Black's most advanced motion separation, and a reinforced edge around the whole perimeter.
15 inches tall, plush (3 out of 10), CertiPUR-US certified foams. (Architecture is from Beautyrest's published spec; per-layer thicknesses are not all disclosed, so we don't list numbers the brand doesn't.)
What's inside Beautyrest Black
Five layers, engineered together: a cool quilted surface, pressure-relieving gel foam, and the Triple-Stranded Pocketed Coil® core that defines the Black line.
Built first for side sleepers who run hot
Side sleepers, the headline fit. Deep cushion lets the shoulder and hip sink while the Triple-Stranded coils keep your spine in line. This is the pressure relief plush exists for.
Hot sleepers who love a soft bed. The one combination most beds force you to choose between: deep plush and the coolest Black hybrid cooling at once. If you've avoided soft mattresses because they sleep hot, this is the model built to settle that.
Couples and light-sleeping partners. Each coil moves on its own and the Triple-Stranded core is Beautyrest Black's most advanced motion separation, so someone climbing in late barely carries across the bed.
Luxury-plush seekers. Flagship cushion with the most micro coils in the line and a reinforced edge, for anyone who wants the top of the ladder with nothing held back.
Back sleepers who prefer soft. A plush surface with real coil support underneath works well, as long as you genuinely like sinking in rather than lying on top.
Stomach and many heavier sleepers, be honest with yourself. You'll likely want a flatter, firmer plane than a 3-out-of-10 gives. The firm or medium XCS is the smarter feel, and the floor will point you straight to it.

Frequently asked questions
How firm is the Series Five XCS Plush?
About a 3 out of 10, a true plush: a deep, pressure-relieving cushion at the shoulder and hip riding on a supportive coil core, so it cradles without sagging.
Does it really sleep cool for a plush bed?
Cooling is the whole reason the XCS line exists. A cool-to-the-touch Sleep Climate™ Surface sits over Micro Diamond™ Memory Foam treated with BlackICE™ Max, applied to the first cradling layer for 30% more cooling power and to move body heat up to twice as long. No mattress is air conditioning, but this is real engineering aimed at the exact spot a soft bed traps heat, and ten minutes lying down tells you more than any spec.
What makes XCS different from the standard Beautyrest Black Hybrid?
XCS expands the Black Hybrid line with two things the standard models don't have: BlackICE™ Max cooling (its most advanced cooling system) and a ContourCover™ that enables split-head sizing. If cooling and split-head adjustability matter to you alongside flagship pressure relief, XCS is the line to feel.
How is Series Five different from Series Three and Series Four XCS?
All three share the Triple-Stranded Pocketed Coil® core and the same BlackICE™ Max cooling. Series Three uses that coil system on its own; Series Four adds one 2K micro-coil layer; Series Five is the flagship, the only model with 4K Micro Coils (two stacked 2K layers) plus upgraded FORM™ HD Max foam and a high-density encasement for enhanced edge support. It is also the tallest at 15 inches and is offered only in plush.
What are the Triple-Stranded Pocketed Coils®?
Beautyrest Black's signature support. Each coil is wrapped in its own fabric pocket and twisted from three strands of steel, so the bed supports point by point and a partner's movement barely crosses to your side. It is the source of Beautyrest Black's reputation for support and stillness.
How tall is it, and will my sheets fit?
It stands 15 inches. Deep-pocket sheets rated for 15 inches or more will sit best. Worth measuring against your frame before delivery.
Does it work with an adjustable base, and what is split-head?
Yes. It works on a sturdy platform, a close-slatted base, a solid foundation, or a compatible adjustable base. It also comes in Split Head Queen and Split Head King, which let each person raise or lower their own head section on a split-head adjustable base while still sharing one connected sleep surface.
What foams are inside, and are they certified?
The comfort layers use CertiPUR-US certified foams, which are made without formaldehyde, ozone depleters, prohibited phthalates, or heavy metals and meet low-VOC standards for indoor air quality.
What's the trial and warranty, and how do returns work here?
You get a 100-night trial and Beautyrest's 10-year limited warranty, both honored because Mattress Overstock is an authorized dealer. If it isn't right, the exchange is for store credit toward a bed of equal or greater value (pay the difference); there's no cash refund, and no restocking-fee traps either.
Can I lie on it near me in Kentucky?
Yes. It's on the floor with the rest of the Beautyrest Black line across all five Mattress Overstock showrooms (Lexington on Nicholasville Road, Georgetown, Somerset, London, and Richmond), no appointment needed. Free local delivery, and the old mattress is hauled away. Mattress Overstock has been an independent Kentucky retailer since 2012, rated about 4.7 stars across 535 Google reviews.
