Beautyrest Black® Series One 13.25" Firm Hybrid Mattress
Couldn't load pickup availability
The honest verdict: the Series One Firm Hybrid is firm support in the most compact Black build. At about a 7 out of 10 on a lean 13.25-inch profile, it sits just below the no-cushion Extra Firm and above the cushioned Firm Pillow Top: a genuinely firm, supportive feel for back and stomach sleepers who want a lower-profile bed without giving up Beautyrest Black's coil support. If you want firm and don't need a tall, pillowy mattress, this is the efficient pick.
What it's made of, and what that does for you
- A firm 7/10 feel. Supportive and on-top, keeping your hips lifted and your spine level, without the absolute hardness of the Extra Firm.
- Triple-Stranded Pocketed Coil® core. Individually-wrapped coils tuned firm for support, with the motion separation Black is known for.
- Beautyrest® Gel Memory Foam + Sleep Climate™. A measured comfort layer relieves surface pressure without softening the firm feel; cool-touch quilting and a breathing coil core keep it cool.
- A compact 13.25-inch profile. Lower and leaner than the pillow-top models, easy to dress, stable on platforms and adjustable bases, and a clean fit for tighter bed frames.
- Premium Black build, 10-year warranty. Firm support in the brand's top line, with CertiPUR-US certified foams, in an efficient build.
The first few minutes lying on it
Lie down on your back and the bed pushes back right away. You sit on top rather than sinking in, hips held up and lower back supported, not dropping into a hollow. The quilted surface reads cool from first contact, and the gel memory foam keeps the top from feeling hard, so firm here means supportive, not punishing. Roll onto your stomach and the hips stay up, the spine stays in line, none of the sag a softer bed gives you face-down.
Who it's not for, said straight
- Side sleepers. A 7/10 firm will press on your shoulder; the Plush Pillow Top or a medium is the better fit.
- If you want the firmest possible feel. The Extra Firm goes further; if you want firm with a cushioned top, the Firm Pillow Top.
- If you want a tall, plush profile. This is deliberately compact and firm.
Where it sits in the line
Among the three Series One firm feels, this Hybrid lands in the middle and adds one more variable, profile height: the same firm support without the tall comfort stack, so at 13.25 inches it is the leanest of the group. Switching from an older bed gone soft in the middle, the change is immediate, and the compact build is the appeal here, not a compromise.
Living with it: motion and heat
Two things matter most once it's in the room. On motion, the pocketed coils move independently, so when one person shifts or gets up, the other side stays steady. On heat, the cool-touch quilting works at the surface while a coil core breathes more than all-foam can. The lean profile keeps it easy to live with: standard sheets fit without a deep stack, and it sits stable on a platform, a foundation, or an adjustable base.

What makes this mattress different
Firm support, compact build
A 7-out-of-10 feel on a lean 13.25-inch profile: firm coil support without a tall, pillowy mattress.
Triple-Stranded Pocketed Coil® core
Individually-wrapped coils tuned firm to keep hips lifted and the spine level, with the motion separation Black is known for.
Sleeps steady for two
Pocketed coils move independently, so when one person shifts or gets up, the other side barely feels it.
Measured comfort layer + Sleep Climate™
Just enough Beautyrest® Gel Memory Foam to ease the surface without softening the firm feel; cool-touch quilting and a breathing coil core fight heat.
Built for back and stomach sleepers
The firm, on-top feel holds the hips up and the lower back flat, exactly what face-down and on-the-back sleepers need.
Compact 13.25-inch build, fits any base
Lower and leaner than the pillow-top models, easy to dress with standard sheets and stable on a platform, foundation, or adjustable base.
Premium Black line, 10-year warranty
Firm support in the brand's top collection, with CertiPUR-US certified foams and a 10-year limited warranty.
Firm support in the leanest Series One profile
Work down through the Firm Hybrid and every layer is doing one job: hold you up. It opens with a cool-touch quilted surface carrying Sleep Climate™ Technology, the part you feel first, drawing heat off the skin instead of trapping it.
Under the quilt sits a measured layer of Beautyrest® Gel Memory Foam. It is deliberately thin: enough to take the hard edge off the surface and ease pressure at the shoulder and hip, but not so much that it softens the firm feel you came for.
Then the bed shows its hand. A firm-tuned Triple-Stranded Pocketed Coil® support core carries the weight, each coil wrapped and working on its own to keep your hips lifted and your spine level. Those same independent coils give the Black line its motion separation and let air move through the core in a way all-foam beds can't.
At 13.25 inches it is the most compact Series One build, and that is the point: a firm bed doesn't need a tall comfort stack, so you get the same firm support in a profile that's easier to dress and fits tighter or lower frames.
Want it firmer still? The Extra Firm (8/10) drops nearly all the cushion. Want firm with a cushioned top? The Firm Pillow Top (6/10) adds one. See the range 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.
Firm support for back and stomach sleepers who want it lean
Back sleepers. Firm coil support keeps the spine level and the hips from dropping into a hollow, in a profile that's easy to get in and out of.
Stomach sleepers. The firm, on-top feel stops the hips from sagging and the lower back from arching, the sore-back trap a softer bed sets face-down.
Couples. The pocketed coils move independently, so a restless partner or an early alarm stays on their own side of the bed.
People who want firm without bulk. A compact 13.25-inch build that fits tighter or lower frames and dresses with standard sheets, no deep-pocket hunt.
Adjustable-base sleepers. The lean, firm build sits stable on a platform, a foundation, or an adjustable base without a tall stack fighting the bend.
Probably not for you if you sleep on your side, where a 7/10 will press on the shoulder (a medium or the Plush Pillow Top suits better), or you want a tall, cushioned surface to sink into.

Frequently asked questions
How firm is the Series One Firm Hybrid?
About a 7 out of 10: firm and supportive, just below the Extra Firm's 8/10. You sleep on top of the bed with your hips lifted, on a compact 13.25-inch build.
How is it different from the Firm Pillow Top and Extra Firm?
It sits between them. The Extra Firm (8/10) has almost no cushion; the Firm Pillow Top (6/10) adds a cushioned top. This Firm Hybrid is firm (7/10) in the most compact, lean profile.
Why choose a more compact 13.25-inch mattress?
Firm beds don't need a tall comfort stack, so a leaner profile gives you the same firm support in a build that's easier to dress with standard sheets and fits tighter or lower bed frames. It's an efficient, no-excess choice.
Is it a hybrid?
Yes. Beautyrest® Gel Memory Foam over a firm-tuned Triple-Stranded Pocketed Coil® support core. The coils provide the firm support and Black's motion separation.
Is it good for couples and motion?
Yes. The Triple-Stranded Pocketed Coils move independently, so when one person rolls over or gets up, the motion barely crosses to the other side. It's one of the things the Beautyrest Black line does best.
Does it sleep hot?
It's built to run cool for a firm bed. The cool-touch quilted surface with Sleep Climate™ Technology pulls heat off the skin, and the pocketed-coil core lets air move through in a way all-foam beds can't. If sleeping hot is your single biggest issue, lie on it in one of our showrooms and judge for yourself.
What's the warranty, and are the foams certified?
It carries a 10-year limited warranty, and the foams are CertiPUR-US certified, made without ozone depleters, formaldehyde, or prohibited phthalates and tested for low VOC emissions.
Will it work on an adjustable base or a platform bed?
Yes. The lean, firm build is stable on a platform, a standard foundation, or an adjustable base, and the lower profile keeps it easy to live with on any of them.
Is an overstock mattress used, a second, or last year's model?
No. Mattress Overstock sells current-model, first-quality Beautyrest Black mattresses, brand-new and in the box, at the manufacturer's authorized price. The name is about how the store keeps prices low, not the condition of the bed.
