Beautyrest Black® Hybrid Series Five XCS 15" Plush Mattress – The Top-Tier Cooling Plush Hybrid in Kentucky
Sink into the most luxurious sleep Beautyrest builds with the Beautyrest Black® Hybrid Series Five XCS 15" Plush Mattress, available now at Mattress Overstock in Kentucky. Series Five sits at the very top of the Beautyrest Black XCS line: 15 inches of advanced engineering that pairs the line's most powerful cooling system with the deepest cradling plush feel. It combines Triple-Stranded Pocketed Coil® support, BlackICE™ Max Cooling Technology, and an exclusive 4K Micro Coil layer (the only XCS model with two layers of 2K micro coils) to deliver pillowy pressure relief without sacrificing precise, individualized back support. If you sleep on your side, you run hot, and you want the richest plush surface money can buy, this is the flagship.
✨ Key Features of the Beautyrest Black® Hybrid Series Five XCS 15" Plush Mattress
🌀 Triple-Stranded Pocketed Coil® Technology
Beautyrest Black's most advanced support coil wraps three intertwined strands of steel into each individually pocketed coil for stronger, more durable, more precisely targeted support exactly where your body needs it. Because every coil moves independently, partner movement is absorbed instead of transferred across the bed — Beautyrest Black's best-in-class motion separation.
❄️ BlackICE™ Max Cooling Technology — 30% More Cooling Power
BlackICE™ Max is built into the first deeply-cradling memory foam layer to deliver 30% more cooling power and pull body heat away up to 2X longer for a cooler, longer-lasting sleep. It is the most advanced cooling system in the entire Beautyrest Black line — noticeably cooler than the standard, non-XCS Black Hybrid models.
🧊 ContourCover & Cool-to-the-Touch Sleep Climate Surface
The sleek ContourCover zipper design is topped with a Sleep Climate Surface that feels genuinely cool the moment you lie down, managing temperature across the night for a temperature-balanced rest. The ContourCover design is also what makes split-head sizing possible, so you and your partner can adjust your head positions independently.
💎 4K Micro Coils — Two Layers of 2K Micro Coils (Series Five Exclusive)
Series Five is the only XCS model built with 4K Micro Coils — two stacked layers of 2,000 micro coils. These tiny, ultra-responsive coils sit in the comfort layers above the support core to hug every curve, fill in the gaps at your lower back and shoulders, and add an extra dimension of individualized, dynamic support that foam alone cannot match. This is the single biggest upgrade over Series Four (one 2K layer) and Series Three (no micro coils).
🛏️ FORM HD Max & FORM HD Material Foams
Premium FORM HD Max Material is layered over FORM HD Material to deliver high-density, body-contouring pressure relief at the hips and shoulders while keeping the plush surface buoyant and supportive — never sinking or sluggish.
🛡️ High-Density Foam Encasement — Enhanced Edge Support
A High-Density Foam Encasement rings the entire perimeter, giving you a firmer, more stable edge to sit on and a larger usable sleep surface — a Series Five enhancement that the lower XCS tiers do not include.
🔁 How XCS Compares — and Why Series Five Sits at the Top
The XCS range expands the Beautyrest Black Hybrid family by adding the more advanced BlackICE™ Max Cooling Technology (30% more cooling power, moves heat up to 2X longer) plus the sleek ContourCover that enables split-head sizing — neither of which the standard, non-XCS Black Hybrid (or the step-down LX-Class) offers. Within XCS itself, the tiers build on one another: Series Three is the entry XCS, using the base Triple-Stranded Pocketed Coil® system with no micro coils; Series Four adds a single layer of 2K Micro Coils for extra contouring support; and Series Five — this model — is the flagship, the only one with 4K Micro Coils (two layers of 2K), upgraded FORM HD Max Material, and a High-Density Foam Encasement for enhanced edge support. At 15 inches it is also the tallest XCS build, and it is offered exclusively in this Plush feel for the deepest cradle in the line.
💬 Who Is the Beautyrest Black® Hybrid Series Five XCS 15" Plush Ideal For?
This is a true plush mattress — a 3 out of 10 on the firmness scale (10 = firmest) — engineered to let you settle in and feel cradled rather than perched on top. It is especially well suited to:
- Side sleepers: The plush surface and 4K micro coils relieve pressure at the shoulders and hips, the two spots that take the most load when you sleep on your side.
- Hot sleepers: BlackICE™ Max plus the cool-to-the-touch Sleep Climate Surface make this the coolest-sleeping plush mattress Beautyrest builds.
- Couples: Triple-Stranded Pocketed Coils isolate motion so a partner's movement won't wake you, and split-head sizes let each person adjust independently.
- Luxury and comfort-first shoppers: If you want the richest, deepest-cradling feel in the Black line and the most micro-coil support available, Series Five is the flagship.
- Lighter-weight sleepers who feel firmer mattresses as too hard, and who want to sink in for genuine pressure relief.
Strict back- and stomach-sleepers who want to sleep more on top of the mattress may prefer a firmer Series Five-equivalent feel or a Medium XCS model — our team can steer you to the right firmness in the showroom.

🧺 Mattress Care
To keep your Beautyrest Black® Hybrid Series Five XCS Plush performing at its best:
- Use a breathable, waterproof mattress protector to guard against spills and allergens without trapping heat.
- Rotate head-to-foot every 3–6 months (especially in the first two years) for even wear. Do not flip — this is a one-sided design.
- Support it on a sturdy compatible foundation or adjustable base, with center support for Queen, King, and Cal King sizes.
- Spot clean stains with mild detergent and water; blot gently without soaking and let it air dry fully. Do not machine wash the cover.
- Vacuum the surface occasionally with an upholstery attachment to remove dust.

What makes this mattress different
Top-tier hybrid support
Series Five is the flagship XCS build: a Triple-Stranded Pocketed Coil core plus the line's only 4K Micro Coil layer (two layers of 2K micro coils) for the deepest, most individualized support in the Beautyrest Black range.
Most advanced cooling
BlackICE Max Cooling Technology delivers 30% more cooling power and moves body heat away up to 2X longer, topped by a cool-to-the-touch Sleep Climate Surface — cooler than any non-XCS Black Hybrid.
Plush pressure relief
A true plush feel (3 out of 10) with FORM HD Max and FORM HD foams over 4K micro coils, cradling the shoulders and hips for side and combination sleepers without feeling sluggish.
Enhanced edge & adjustable-base ready
A High-Density Foam Encasement gives Series Five enhanced edge support, and the ContourCover design works with adjustable bases and enables Split Head Queen and Split Head King sizes.
Series Five builds the feel on Triple-Stranded Pocketed Coils, then adds 4K micro coils no other XCS model has
Like every Beautyrest Black Hybrid, Series Five does its heavy support work with independently wrapped coils — here the Triple-Stranded Pocketed Coil, Beautyrest Black's most advanced and most durable coil. That keeps the surface stable and the motion isolation excellent while preserving easier movement than an all-foam bed.
What sets Series Five apart is what sits above that core: two stacked layers of 2K micro coils (4K total), a layer no other XCS model carries. These ultra-responsive micro coils contour to your lower back and shoulders, adding a dimension of dynamic, individualized support that foam alone cannot provide — then BlackICE Max Cooling foam and a cool-to-the-touch Sleep Climate Surface manage heat on top.
Compared with Series Four (a single 2K micro-coil layer) and Series Three (the base XCS with no micro coils), Series Five also adds upgraded FORM HD Max Material and a High-Density Foam Encasement for enhanced edge support. That is the practical difference you feel in the showroom: a taller, plusher, cooler surface that still pushes back with precise coil-on-coil support.
Shop all Beautyrest mattresses →Built for side sleepers, hot sleepers, and luxury comfort seekers
Side sleepers - The plush surface and 4K micro coils relieve pressure at the shoulders and hips, the two spots that carry the most load on your side, so you settle in instead of bridging across pressure points.
Hot sleepers - BlackICE Max Cooling plus the cool-to-the-touch Sleep Climate Surface make this the coolest-sleeping plush mattress in the Beautyrest Black line, drawing heat away up to 2X longer.
Couples - Triple-Stranded Pocketed Coils absorb partner movement instead of transferring it, and Split Head Queen and Split Head King options let each person raise their head independently.
Luxury and comfort-first shoppers - At 15 inches with the line's only 4K micro-coil layer and a true plush feel, Series Five is the flagship cradle of the Black range for shoppers who want to sink in and be enveloped.

Frequently asked questions
How is the Beautyrest Black Hybrid Series Five XCS Plush different from the Series Four XCS?
Both are XCS Black Hybrids with BlackICE Max Cooling and the ContourCover, but Series Five is the step up. Series Four uses a single layer of 2K micro coils; Series Five is the only model with 4K Micro Coils (two stacked 2K layers) for more individualized support, plus upgraded FORM HD Max Material and a High-Density Foam Encasement for enhanced edge support. Series Five is also taller at 15 inches. If you want the richest, deepest plush feel and the most micro-coil support in the line, choose Series Five.
Does it work with an adjustable base, and can I get a split-head version?
Yes. The Series Five XCS Plush is compatible with adjustable bases, and the ContourCover design enables split-head sizing. We offer it in Split Head Queen and Split Head King so you and your partner can raise and lower your head positions independently without splitting the whole sleep surface.
How fast can I get it delivered in Kentucky?
We deliver with our own team across Kentucky — including Lexington, Georgetown, Somerset, London, and Richmond. Most orders arrive the next business day when the size is in stock. Pickup is also available at our showroom locations.
What if I do not like it after a few nights?
You have 100 days to make sure the comfort is right. We usually recommend giving any new mattress at least 21 nights before making a comfort decision, because the cover, foams, and micro coils need time to settle and your body needs time to adjust to a new plush surface.
How firm is the Beautyrest Black Hybrid Series Five XCS Plush?
We rate it 3 out of 10 (10 = firmest), which is a true plush. You sleep more in the mattress than on top of it, with deep cradling pressure relief at the shoulders and hips. It is ideal for side and combination sleepers and lighter-weight sleepers; strict back- or stomach-sleepers who want a firmer, more on-top feel should compare it against a Medium XCS model in our showroom.
Is this mattress good for hot sleepers?
It is the coolest plush mattress Beautyrest builds. BlackICE Max Cooling Technology is applied to the first cradling memory foam layer for 30% more cooling power and pulls heat away up to 2X longer, and it is topped by a cool-to-the-touch Sleep Climate Surface. Together they form the most advanced cooling system in the XCS line — noticeably cooler than the standard non-XCS Black Hybrid.
