Beautyrest Black® Series One 14.25" Medium Mattress
Couldn't load pickup availability
The honest verdict — the Black Series One Medium is the way into Beautyrest's premium line, and what you're paying for is under your back, not on top of it: Triple-Stranded Pocketed Coils, hundreds of individually-wrapped springs that respond point by point instead of as one slab. At a true medium (about 5 out of 10) you get a layer of gel memory foam for contour, but the support and the famously quiet motion separation come from the coils. If you want the Beautyrest Black feel — responsive, supportive, cool — at the most accessible point in the line, start here.
What it's made of — and what that does for you
- Triple-Stranded Pocketed Coil® support. Each coil is wrapped and works on its own, so the bed holds your lower back and shoulders independently and barely passes a partner's movement across — Beautyrest's signature, and the reason Black is known for motion separation.
- Beautyrest® Gel Memory Foam. A contouring comfort layer that relieves pressure at the shoulders and hips without the deep, slow sink of an all-foam bed. You rest more on this bed than in it.
- Sleep Climate™ Technology. A cool-touch quilted surface and heat-management layer — and the coil core already breathes more than foam. (Honest note: no mattress is air-conditioning; if you sleep extremely hot, a higher Black series adds more cooling.)
- A true medium, 14.25 inches. The most universal firmness in the line — broad enough for back, side, and combination sleepers. Worth measuring 14.25 inches against your frame and deep-pocket sheets.
- Premium build, 10-year warranty. Beautyrest Black is the brand's top tier; Series One is its foundation, built around the same coil technology that defines the whole line.
Who it's not for — and we'd rather say so now
- If you want the deep memory-foam "hug" — this is a coil hybrid: supportive and responsive, not enveloping. If you want to sink in and feel cradled, an all-foam bed is the better match, and we'll show you one.
- If you want softer or firmer than medium — Series One comes in several feels. Want plush? The Series One Plush Pillow Top adds a cushioned top. Want firmer support? The Firm Pillow Top is the call.
- If you want maximum cooling or pressure relief — that's what the higher tiers buy: Series Two adds enhanced cooling and a deeper comfort layer, and Series Three steps up to 2K Micro Coils. If those are priorities, feel the step up in the full Beautyrest Black lineup.

What makes this mattress different
Triple-Stranded Pocketed Coil® support
Hundreds of individually-wrapped coils respond point by point — the source of Beautyrest Black's support and its signature motion separation.
The entry into Beautyrest Black
The brand's top tier at its most accessible point — the same defining coil technology as the rest of the Black line, in a true medium feel.
Gel memory foam + Sleep Climate™
A gel-foam comfort layer contours and relieves pressure, while Sleep Climate cooling and a coil core that breathes keep the surface from banking heat.
Premium build, 10-year warranty
A 14.25-inch Beautyrest Black hybrid backed by a 10-year warranty, built around the coil tech that defines the line.
The support is in the coils — that's the whole Beautyrest Black idea
Most of what you feel on a Black Series One comes from the Triple-Stranded Pocketed Coil® system: each coil is individually wrapped, so it compresses where your body presses and stays firm where it doesn't. That's what lets the bed support your lumbar while cradling your shoulder, and it's why a partner's movement barely crosses the mattress.
On top sits Beautyrest® Gel Memory Foam for contouring pressure relief, under a quilted surface with Sleep Climate™ Technology for heat management. The result is a true medium that feels responsive and supportive rather than sinking — the opposite of an all-foam bed.
Series One is the foundation of the Black line. Step up and the upgrades are specific: Series Two adds enhanced cooling and a deeper comfort layer; Series Three brings 2K Micro Coils for even more individualized response. Feel the ladder in the full Beautyrest Black lineup and decide how far up it's worth going.

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 for sleepers who want support, not sink
Back and combination sleepers — a true medium over individually-wrapped coils gives contour without losing the support your back wants when you change position.
Couples — Triple-Stranded Pocketed Coils are Beautyrest's most advanced motion separation; if one of you moves all night, the other side stays still. One of the quietest beds we carry for motion.
People stepping up from a worn-out foam bed — if you've felt the dead, sinking feeling of an old all-foam mattress, the responsive coil support here is the antidote.
Probably not for you if — you want the deep memory-foam hug (an all-foam bed suits you better), or you want a plusher or firmer surface — in which case the Plush Pillow Top or Firm Pillow Top Series One is the better fit.

Frequently asked questions
How firm is the Beautyrest Black Series One 14.25" Medium?
A true medium — about 5 out of 10, where 10 is firmest. You feel a gel-foam contour layer at the surface, but the support comes from the Triple-Stranded Pocketed Coils underneath, so it reads responsive and supportive rather than sinking. It suits back, side, and combination sleepers.
Is it memory foam or a hybrid?
A hybrid. The core is Triple-Stranded Pocketed Coil® technology — individually-wrapped springs — with a layer of Beautyrest® Gel Memory Foam on top for pressure relief. That coil core is what gives Black its support and its motion separation; you rest more on this bed than in it.
What do the higher Beautyrest Black series add?
Specific upgrades. Series Two adds enhanced cooling and a deeper comfort layer; Series Three steps up to 2K Micro Coils for more individualized support; the top tiers add more of both. Series One is the foundation with the same defining coil technology. Feel the difference in the full Black lineup.
How does it handle motion if I share the bed?
Very well — Triple-Stranded Pocketed Coil® technology is Beautyrest's most advanced motion separation. Because each coil moves independently, a partner getting up or shifting barely registers on your side. It's one of the strongest reasons couples choose Black.
How do delivery and the comfort guarantee work?
We deliver across Kentucky with our own team, usually next business day when your size is in stock, and we haul the old mattress away. You also get a 100-day comfort guarantee: if the feel isn't right, exchange it for store credit toward any bed of equal or greater value (no cash refund). Give a new bed about three weeks to adjust before deciding.
Can I try it before I buy?
Yes — and with a premium hybrid it's worth it. The Black Series One is on our floors across Kentucky (Lexington, Georgetown, Somerset, London, and Richmond), so you can feel the coil support in your real sleeping position and compare it against the rest of the Black ladder. A couple of minutes settles it.
