Beautyrest Black® Series One 14.25" Medium Mattress
Couldn't load pickup availability
The honest verdict: the Black Series One Medium is the most accessible way into Beautyrest's top line, and what you are paying for sits under your back, not on top of it. The core is the Triple-Stranded Pocketed Coil, hundreds of individually wrapped springs that respond point by point instead of moving as one slab. At a true medium (about 5 out of 10) a layer of gel memory foam handles contour at the surface, but the support and the famously quiet motion separation come from those coils. This is the quilted-top Black, the classic Beautyrest feel: you rest on the bed, not down inside it. If that is the feel you want at the entry point of the line, start here.
What you notice in the first few minutes
Lie down and the bed meets you instead of swallowing you. Your hips and shoulders settle into the gel foam while your lower back stays held, because the coils compress where you press and stay firm where you do not. Roll from back to side and it keeps up instead of leaving you in the dent you just made. A true medium is the feel most people settle into for the long haul, and Beautyrest itself rates the Medium feel as the option ideal for all sleepers, broad enough for a back, side, or combination sleeper to share. Give any new bed about three weeks before you judge it.
Quilted-top, not the smooth-top Hybrid
Series One Medium comes in two surface styles that feel different the moment you lie down. This is the quilted-top Medium: Beautyrest defines its quilted surface as a stitched, structured top with a clean, sink-free feel, the traditional Beautyrest Black. Prefer a smooth top that contours a little more closely? That is the Series One Medium Hybrid, the same true-medium support over the same coil core, just a smoother surface. A minute on each settles which one is yours.
What it is 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 cool-touch quilt. A quilted, cool-touch surface that helps move heat away from the body, and the coil core already breathes more than foam. Honest note: no mattress is air conditioning, so if you sleep extremely hot, a higher Black series adds more cooling.
- Premium finish, 14.25 inches. The luxe details Beautyrest builds into Series One: eight handles for easy maneuvering, velvet accents, a quilted border, and a cashmere-blend cover. Worth measuring 14.25 inches against your frame and deep-pocket sheets.
- Built to last, 10-year warranty. CertiPUR-US certified foams and a 10-year limited warranty, built around the coil technology that defines the whole Black line. Adjustable-base compatible if you like to raise your head or feet.
Who it is not for, and worth saying now
- If you want the deep memory-foam hug: this is a coil bed, supportive and responsive, not enveloping. To sink in and feel cradled, an all-foam bed is the better match, and the floor team can show you one.
- If you want softer or firmer than medium: Series One spans several feels. Want a cushioned plush top? The Plush Pillow Top. Want firmer support? The Firm Pillow Top, or the very firm Extra Firm.
- If maximum cooling or pressure relief is the priority: that is what the higher tiers buy. Series Two adds enhanced cooling and deeper memory-foam comfort layers; Series Three steps up the micro-coil and latex layers again. Feel the step up across the full Beautyrest Black lineup.

What makes this mattress different
Triple-Stranded Pocketed Coil® support
Hundreds of individually wrapped coils respond point by point. This is the source of Beautyrest Black's support and its signature motion separation, the part of the bed you are really paying for.
The quilted entry into Beautyrest Black
The brand's introductory Black tier, with the same defining coil technology as the rest of the line, in a quilted-top true medium feel.
A true medium, about 5 out of 10
Beautyrest rates the Medium feel as the option ideal for all sleepers, broad enough for back, side, and combination sleepers, and the feel most people settle into for the long haul.
Beautyrest® Gel Memory Foam for pressure relief
A gel memory foam comfort layer contours at the shoulders and hips and relieves pressure without the deep, slow sink of an all-foam bed.
Sleep Climate™ cool-touch quilt
A quilted, cool-touch surface that helps move heat away from the body, helped by a coil core that breathes more than foam, so the bed manages heat better than a solid-foam build.
Quiet for couples
Because every coil moves on its own, a partner getting up or turning over barely crosses to your side. One of the quietest beds on the floor for motion.
Premium finish, 10-year warranty
Series One's luxe details: eight handles, velvet accents, a quilted border, and a cashmere-blend cover, on CertiPUR-US certified foams, backed by a 10-year limited warranty. Adjustable-base friendly.
The support is in the coils: that is the whole Beautyrest Black idea
Most of what you feel on a Black Series One Medium comes from the Triple-Stranded Pocketed Coil® system: individually wrapped coils, each one compressing where your body presses and staying firm where it does not. That is what lets the bed support your lumbar while cradling your shoulder, and it is why a partner's movement barely crosses the mattress.
On top of the coil core sits Beautyrest® Gel Memory Foam for contouring pressure relief, under a quilted, cool-touch surface with Sleep Climate™ Technology for heat management. Series One is finished with the brand's luxe details, eight handles, velvet accents, a quilted border, and a cashmere-blend cover, on CertiPUR-US certified foams. The result is a true medium that reads responsive and supportive rather than sinking, the opposite of an all-foam bed.
This is the quilted-top build. Its sibling, the Series One Medium Hybrid, puts the same coil core under a smooth top for a slightly closer contour. And Series One is the foundation of the Black line: step up and the upgrades are specific. Series Two adds enhanced cooling and deeper memory-foam comfort layers; Series Three steps up the micro-coil and latex layers again for more individualized response and airflow. Feel the ladder in the full Beautyrest Black lineup and decide how far up it is 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 sleepers: a true medium over individually wrapped coils gives you contour at the shoulders without letting your hips drop, so your spine stays in line through the night.
Combination sleepers: the coils respond fast when you change position, so the bed keeps up as you move from back to side instead of leaving you in the dent you just made.
Side sleepers who do not want to sink: the gel-foam top cushions your shoulder and hip while the coils hold underneath. If you have felt a soft bed cave at the hips, this is the supportive answer at a true medium.
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 on the floor for motion.
People stepping up from a worn-out foam bed: if you know the dead, sinking feeling of an old all-foam mattress, the responsive coil support here is the antidote, with premium-tier materials over the top.
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. If you want a smoother, slightly closer contour at the same medium support, lie on the Medium Hybrid.

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. Beautyrest rates its Medium feel as the option ideal for all sleepers, so it suits back, side, and combination sleepers.
Is this the quilted Medium or the Medium Hybrid?
This is the quilted-top Medium. Beautyrest describes its quilted surface as a stitched, structured top with a clean, sink-free feel. The Series One Medium Hybrid uses a smooth top over the same coil core for a slightly closer contour. Same true-medium support, different surface feel, so it comes down to which surface you prefer. Lie on both back to back and the difference is clear in a minute.
Is it memory foam or innerspring?
It is a coil bed with a foam comfort layer. The core is Triple-Stranded Pocketed Coil® technology (individually wrapped springs), topped with Beautyrest® Gel Memory Foam under a cool-touch Sleep Climate™ quilt. That coil core is what gives Black its support and its motion separation, so you rest more on this bed than in it.
What is it actually made of?
From the top down: a quilted, cool-touch Sleep Climate™ surface, a layer of Beautyrest® Gel Memory Foam for contouring pressure relief, and a Triple-Stranded Pocketed Coil® support core. It stands 14.25 inches tall and is finished with Series One's luxe details, eight handles, velvet accents, a quilted border, and a cashmere-blend cover, on CertiPUR-US certified foams.
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 is one of the strongest reasons couples choose Black, and one of the quietest beds on our floor for motion.
How does it sleep for temperature?
Cooler than a solid-foam bed of the same height. The quilted Sleep Climate™ surface is cool to the touch and helps move heat away from the body, and the coil core breathes more than foam can. Honest note: no mattress is air conditioning. If sleeping hot is your single biggest problem, the higher Black series (Series Two and up) add more cooling, and we can show you the step up in person.
What do the higher Beautyrest Black series add?
Specific upgrades. Series Two adds enhanced cooling and deeper high-density memory-foam comfort layers; Series Three steps up the micro-coil and latex layers again for more individualized response and airflow; the top tier adds more of both. Series One is the foundation with the same defining coil technology. Feel the difference across the full Black lineup.
What kind of base or foundation does it need?
It needs solid, even support: a sturdy platform, a proper foundation, or closely spaced slats. It is also adjustable-base compatible if you like to raise your head or feet. Putting a premium coil mattress on a sagging or wide-slatted frame can affect both the feel and the warranty, so set it on a flat, supportive base. If you are not sure your current base will work, the floor team can check it with you.
What size should I get, and will my sheets fit?
Every size stands 14.25 inches tall, so measure that against your frame and your sheets. With a 14.25-inch profile, deep-pocket fitted sheets are the safe call. Sizes run from Twin XL up through Split Cal King. If you are unsure which size fits your room or your base, the floor team can walk you through it in person.
