Beautyrest Black® Series Three 16.75" Plush Pillow Top Mattress
Couldn't load pickup availability
The honest verdict: the Series Three Plush Pillow Top is deep-cushion plush done at the upper tier, a tall 16.75-inch build, about a 3 out of 10, with 2K Micro Coils in the pillow top for individualized support under the softness, Self-Response™ Latex for responsive pressure relief, and Sleep Climate™ cooling. It's the side-sleeper cloud for someone who wants the most refined, best-supported plush Beautyrest Black makes below the flagship. Sink in deep. The hardware underneath keeps your spine honest.
What it's made of, and what that does for you
- A tall, deep plush pillow top (about 3/10). The most cushioned surface in Series Three, with SurfaceTouch™ Gel quilted right in, so your shoulder and hip meet a genuine cloud the moment you lie down.
- 2K Micro Coils in the pillow top. A finer coil layer responds to your contours within the cushion, so deep plush still supports point by point instead of giving way.
- Self-Response™ Latex. Latex returns under your weight to keep the plush responsive rather than dead-soft, so you reposition without fighting the bed.
- Sleep Climate™ Technology, Micro Diamond™ foam, and a cool-to-the-touch cover. Three cooling elements work the surface that deep cushion collects heat on.
- Triple-Stranded Pocketed Coil® core, 16.75 inches. The structural support and motion separation under the comfort layers, compatible with adjustable bases. Plan for deep-pocket sheets and check frame height.
- Premium Black build, 10-year warranty. The refined plush tier, on CertiPUR-US certified foams.
What you notice lying on it
Lie down on your side and the pillow top takes your shoulder and hip first, the cloud closing in around the heaviest parts of you. A beat later you feel the part most plush beds get wrong: support pushing back up under your waist and ribs. That is the 2K Micro Coils answering your contours inside the cushion and the Triple-Stranded Pocketed Coil® core holding the line underneath. Plush on top, structure beneath.
Who it's for, and honestly who it's not
This is the deep-cushion cloud for side sleepers: the deep pillow top gives the shoulder and hip a real place to sink, while the 2K Micro Coils and core keep the spine level rather than letting it bow. It is also for the plush seeker who still wants support, the case for an upper-tier plush hybrid if you are switching from a soft all-foam bed that started to sag in the middle, since the coils carry your spine where foam alone settles. And it suits couples where one partner wants soft, because the pocketed coils isolate motion so the plush partner does not wake the other. Now the honest part.
- Back and stomach sleepers. A 3/10 will likely let your hips dip below your shoulders, and your lower back will feel it by morning. A medium or firm Black is the better fit.
- If you want a more accessible plush. The Series Two Plush Pillow Top is a tall plush without the 2K coils, the latex, and the Micro Diamond™ cooling, the tier below.
- If a very tall bed is a problem. At 16.75 inches plus a foundation this sits high, and that height is real once it is in the room. Measure against your frame and headboard first.

What makes this mattress different
Deep plush, the upper Series Three tier
A tall, deeply cushioned 3-out-of-10 surface, the most refined plush Beautyrest Black makes below the flagship.
2K Micro Coils under the cushion
A finer coil layer built into the pillow top responds to your contours point by point, so deep plush supports you instead of just giving way.
Self-Response Latex keeps it responsive
Latex returns under your weight so the plush feels alive rather than dead-soft, and you reposition without fighting the bed.
Sleep Climate plus Micro Diamond cooling
Sleep Climate Technology, Micro Diamond memory foam, and a cool-to-the-touch cover pull heat off the surface that deep cushion tends to trap.
SurfaceTouch Gel quilted into the surface
Gel memory foam quilted right into the classic plush top gives immediate pressure relief at your shoulders and hips.
Triple-Stranded Pocketed Coil core
The structural support and motion separation under the comfort layers, so a partner's movement barely crosses the bed. Adjustable-base compatible.
Tall 16.75-inch build, 10-year warranty
Among the tallest beds we carry, on CertiPUR-US certified foams. Plan for deep-pocket sheets and check your frame height.
A deep cloud with 2K coils and latex underneath
The Series Three Plush Pillow Top builds the feel from the top down. First a classic quilted surface with SurfaceTouch™ Gel Memory Foam quilted directly into it, the part you feel the instant you lie down, cushioning your shoulders and hips. Below that sits Self-Response™ Latex, which returns under your weight so the plush stays responsive instead of going dead-soft. Inside the pillow top run the 2K Micro Coils: a finer coil layer that answers your contours point by point. That is the line between an upper-tier plush hybrid and a plush foam bed, because foam alone settles where these coils keep supporting.
For cooling, Sleep Climate™ Technology, Micro Diamond™ Memory Foam, and a cool-to-the-touch cover work together to move heat off a surface that deep cushion would otherwise trap. Everything rides on the Triple-Stranded Pocketed Coil® core that gives the bed its 16.75-inch structure, its motion separation, and its adjustable-base compatibility.
For a tall plush without the 2K coils, the latex, or the Micro Diamond cooling, the Series Two Plush Pillow Top is the tier below. See every plush option in the Beautyrest Black lineup.

Five layers, engineered together: a cool quilted surface, pressure-relieving gel foam, and the Triple-Stranded Pocketed Coil® core that defines the Black line.
The deep-cushion cloud for side sleepers
Side sleepers: this is the bed. The deep pillow top gives your shoulder and hip a real place to sink, while the 2K Micro Coils and Triple-Stranded Pocketed Coil® core keep your spine level rather than letting it bow. If a firmer bed has been leaving your shoulder sore, start here.
Plush seekers who still want support: the most refined, best-supported plush in Series Three. You get the cloud feel without the slow sag a soft all-foam bed eventually develops.
Anyone leaving a sagging foam bed: if your soft all-foam mattress started caving in the middle, the coils here carry your spine where foam alone settled. This is the case for an upper-tier plush hybrid.
Couples where one partner runs hot: Sleep Climate™ Technology, Micro Diamond™ foam, and the cool-to-the-touch cover pull heat off a deep-cushion surface better than plush foam alone, while the pocketed coils isolate motion so neither of you wakes the other.
People switching off a too-firm bed: if you keep waking with pressure at the shoulder or hip, a genuine 3/10 with real coil support underneath is the honest fix.
Probably not for you if: you sleep on your back or stomach (a 3/10 will likely let your hips dip below your shoulders and your lower back will feel it by morning, so look at a medium or firm Black), or a very tall bed is a problem for your frame and headboard.

Frequently asked questions
How soft is the Series Three Plush Pillow Top?
A deep plush, about 3 out of 10, and the tallest, most cushioned plush in Series Three. You sink into the pillow top, while 2K Micro Coils and the main coil core keep the softness supported.
Will such a soft, tall bed support my back?
Yes, that's exactly what the 2K Micro Coils and Triple-Stranded Pocketed Coil® core are for. Unlike a soft all-foam bed that can sag, the coils hold your spine level under the deep cushion. It's the case for an upper-tier plush hybrid over plush foam.
How is it different from the Series Two plush?
Series Three adds 2K Micro Coils, Self-Response™ Latex, and Micro Diamond™ cooling. The Series Two Plush Pillow Top is a tall plush without those upgrades, the tier below.
What are the 2K Micro Coils, and why do they matter?
They're a layer of finer coils built into the pillow top itself, above the main support core. In a deep plush bed they respond to your contours point by point, so you sink in without the surface simply collapsing. They're the main reason this plush feels supported rather than soft-and-saggy.
Does a deep plush bed sleep hot?
Deep cushion can trap heat, so this build fights it on three fronts: Sleep Climate™ Technology, Micro Diamond™ Memory Foam, and a cool-to-the-touch cover that pulls warmth off the surface. The pocketed-coil core also breathes more than an all-foam bed of the same softness.
Is it good for side sleepers?
It's built for them. The deep pillow top lets your shoulder and hip settle in, while the 2K Micro Coils and coil core keep your spine from bowing. If a firmer bed has left your shoulder sore in the morning, this is the Black to try first.
Will it work on my adjustable base?
Yes. The Triple-Stranded Pocketed Coil® core flexes with an adjustable base. At 16.75 inches it sits tall, so measure that height plus your base against your frame and headboard before you buy, and plan for deep-pocket sheets.
How good is the motion separation for couples?
Excellent. The Triple-Stranded Pocketed Coils move independently, so when one partner shifts or gets up, the movement barely crosses the bed. It's a strong pick for couples, including when one of you wants the soft side of the bed.
