Beautyrest Black® Series Three 16.5" Firm Pillow Top Mattress
Couldn't load pickup availability
The honest verdict: the Series Three Firm Pillow Top is firm coil support with a cushioned top, done at the upper tier of Beautyrest Black. At about a 6 out of 10 it gives back sleepers firm support while a pillow top softens the surface, and because it's a pillow-top model it gets the 2K Micro Coils for finer individualized support, plus Self-Response Latex and Micro Diamond cooling. It's the firm-but-not-hard, refined pick: supportive enough to keep your spine level, cushioned enough that the surface never feels like a board.
What you notice in the first few minutes lying on it
Sit down and the top has a quiet bit of give, then you settle and the firm core underneath holds: the first inch is cushion, the support below stays honest. Roll onto your back and your hips and shoulders meet the surface without sinking past it, while your lower back stays supported rather than bridging a gap. It does not hug you like a plush bed, and it does not push back like a board either.
What it's made of, and what that does for you
- Firm support, cushioned top (6/10). A pillow top softens the surface while firm coil tuning keeps the support honest: firm without harsh.
- 2K Micro Coils in the pillow top. A finer coil layer responds to your contours inside the cushion, for more individualized support than coils alone. This is the layer you step up to a pillow-top model for.
- Self-Response Latex and SurfaceTouch Gel Memory Foam. Latex springs back as you move and the gel foam is quilted into the surface, so pressure relief is responsive rather than slow and sinking.
- Sleep Climate cooling with Micro Diamond Memory Foam. A cool-to-the-touch cover and Micro Diamond foam pull heat off the surface, so the cushioned top sleeps cool instead of trapping warmth the way some pillow tops do.
- Triple-Stranded Pocketed Coil core, 16.5 inches. Firm support plus Beautyrest's most advanced motion separation under the comfort layers. Plan for deep-pocket sheets.
- Premium Black build, 10-year limited warranty. CertiPUR-US certified foams, and it works on an adjustable base if you like raising the head or feet.
Who it suits, and who it doesn't
This is built for the back sleeper who wants firm support with a soft landing: the firm coil support keeps your spine level, while the pillow top and 2K coils make the surface precise rather than punishing. Combination sleepers who lean firm fit it well too, with enough support for back and stomach and enough give to make rolling to the side easy. Honestly though, it is not for everyone:
- If you want a true rock-firm surface, the pillow top adds give; the Series Three Extra Firm is the no-cushion call, sitting around an 8 out of 10 where this one lands near a 6.
- Dedicated side sleepers: at a 6/10 your shoulder may want more give, and the Series Three Plush Pillow Top is the deeper cradle in the same family.
- If a tall bed is a problem, at 16.5 inches plus a foundation this sits high; measure your frame first.
Living with it over time
If you share the bed, this is an easy one to live with. The Triple-Stranded Pocketed Coils move independently, so a partner shifting or getting up barely crosses to your side. The coil core breathes more than an all-foam build, which is why the cushioned top stays cooler than most pillow tops. It is also adjustable-base compatible, so raising the head or feet works without changing the mattress.

What makes this mattress different
Firm support, cushioned top (6/10)
A pillow top softens the surface while firm coil tuning keeps the support honest: firm without harsh.
2K Micro Coils in the pillow top
A finer coil layer responds to your contours inside the cushion for more individualized support, the reason to step up to a pillow-top model.
Self-Response Latex and SurfaceTouch Gel
Latex springs back as you move and gel foam is quilted into the surface, so pressure relief is responsive instead of slow and sinking.
Sleep Climate cooling with Micro Diamond foam
A cool-to-the-touch cover and Micro Diamond Memory Foam pull heat off the surface so the cushioned top sleeps cool.
Triple-Stranded Pocketed Coil core
Beautyrest's most advanced motion separation and firm support under the comfort layers, so a partner's movement barely crosses the bed.
16.5-inch build, deep-pocket sheets
A tall, substantial profile; plan for deep-pocket sheets and measure your frame before delivery.
10-year warranty, adjustable-base ready
CertiPUR-US certified foams, a 10-year limited warranty, and compatibility with an adjustable base.
Firm support, cushioned top, with 2K coils
Work from the top down. The surface is a quilted pillow top with SurfaceTouch Gel Memory Foam for immediate pressure relief, then Self-Response Latex that springs back as you move. Built into that pillow top are the 2K Micro Coils, a finer coil layer that responds to your contours inside the cushion, which is what a pillow-top model in this series gives you over the firm and extra-firm builds.
Cooling runs through the top with Sleep Climate technology: a cool-to-the-touch cover and Micro Diamond Memory Foam that help pull heat off the surface. Underneath sits the firm-tuned Triple-Stranded Pocketed Coil core, 16.5 inches in total, which carries the firm support and delivers Beautyrest's most advanced motion separation so a partner shifting barely reaches your side. Foams are CertiPUR-US certified and the build carries a 10-year limited warranty.
The pillow top softens the feel to a 6/10; the firm core and 2K coils keep the support precise and honest. Want true rock-firm with no cushion? The Series Three Extra Firm. Want a deeper cradle? The Plush Pillow Top. See every firm tier 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.
For the back sleeper who wants firm with a soft landing
Back sleepers: the sweet spot. Firm coil support keeps your spine level while the pillow top and 2K coils make the surface comfortable and precise rather than punishing.
Combination sleepers who lean firm: supportive enough for back and stomach, with enough surface give to make rolling to the side easy.
Couples: the Triple-Stranded Pocketed Coils isolate movement, so one of you turning over or getting up barely reaches the other side.
Hot sleepers on the surface: the Sleep Climate cover and Micro Diamond foam over a breathing coil core keep the cushioned top cooler than most pillow tops.
Adjustable-base owners: it flexes for a base, so raising the head or feet works without changing the mattress.
Probably not for you if you want a true rock-firm deck (look at the Extra Firm) or you are a dedicated side sleeper who needs a deep cradle for the shoulder and hip (the Plush Pillow Top goes softer).

Frequently asked questions
How firm is the Series Three Firm Pillow Top?
About a 6 out of 10: firmer than medium, softer than the Extra Firm. The pillow top cushions the surface while the firm core and 2K Micro Coils keep the support precise. Firm but not harsh.
Does it have the 2K Micro Coils?
Yes. As a pillow-top model it gets the 2K Micro Coils, a finer coil layer built into the pillow top for more individualized support, along with Self-Response Latex and Micro Diamond cooling. The firm and extra-firm builds in this series do not include them.
How is it different from the Extra Firm?
The Series Three Extra Firm is around an 8 out of 10 with almost no cushion. This Firm Pillow Top keeps firm support but adds a cushioned top and the 2K coils, landing near a 6 out of 10.
Is it a good choice for side sleepers?
For a dedicated side sleeper, probably not. At a 6 out of 10 the surface may not give your shoulder and hip enough room to settle. In the same family the Series Three Plush Pillow Top is the deeper cradle. Combination sleepers who spend part of the night on their back tend to do well here.
Does it sleep hot?
It is built to sleep cool for a pillow top. Sleep Climate technology pairs a cool-to-the-touch cover with Micro Diamond Memory Foam to pull heat off the surface, and the Triple-Stranded Pocketed Coil core breathes more than an all-foam bed, so heat has somewhere to go.
Is it good for couples and motion transfer?
Yes. The Triple-Stranded Pocketed Coils move independently and deliver Beautyrest's most advanced motion separation, so a partner shifting or getting up at night barely crosses to your side.
Will it work on an adjustable base?
Yes, it is compatible with an adjustable base, so you can raise the head to read or the feet to take pressure off your legs without changing the mattress. Ask the floor about pairing it with a base when you come in.
How tall is it and what sheets do I need?
It stands 16.5 inches tall, so on a foundation or adjustable base it sits high; measure your frame first. Plan for deep-pocket fitted sheets to fit the profile.
What about the warranty, certifications, and the comfort guarantee?
The mattress carries a 10-year limited warranty and uses CertiPUR-US certified foams. From Mattress Overstock you also get a 100-day comfort guarantee: if the feel is not right, exchange it for store credit toward any bed of equal or greater value (pay the difference, no cash refund).
