Beautyrest Black® Series Two 15.25" Medium Apex Top Hybrid Mattress
Couldn't load pickup availability
The honest verdict: the Series Two Apex Top Medium is the standout of the Series Two line, and the reason is the edges. The Apex Top is built around BeautyEdge® encasement, a reinforced perimeter that keeps the whole surface usable. You can sleep, sit, and roll near the edge without the rolling-off-a-hill feeling cheaper beds give you. Stack on the Series Two upgrades over Series One (Micro Diamond™ cooling and a deeper, more contouring comfort layer) on a true-medium feel, and you get the most well-rounded medium in the Black core line. If you share your bed or use its full width, this is the one to come feel.
What it's made of, and what that does for you
- Apex Top with BeautyEdge® encasement. A reinforced perimeter so the edges hold firm: more usable sleeping surface, a solid seat on the side, and a steadier feel getting in and out.
- The Series Two cooling step-up. Sleep Climate™ quilting plus Micro Diamond™ Memory Foam, infused with heat-conductive particles that pull warmth away from your body, so the deeper comfort layer runs cooler than Series One.
- Beautyrest® Gel Memory Foam, deeper than Series One. A more contouring comfort layer that cradles your curves and takes pressure off your hips and shoulders.
- Triple-Stranded Pocketed Coil® core. Each individually-wrapped coil uses three braided steel strands, so it responds on its own: a true-medium support with Black's signature motion separation.
- A substantial 15.25-inch hybrid. Taller than the Series One mediums to make room for the deeper comfort and the Apex Top. Measure against your frame and plan on deep-pocket sheets.
- Premium Black build, 10-year limited warranty. CertiPUR-US certified foams, adjustable-base compatible, and the most well-rounded medium in the Black core lineup.
What you notice lying on it
In the middle, the feel reads as a genuine medium, about 5 out of 10: enough give to take pressure off your hips and shoulders, enough support to keep your spine honest rather than letting you sink. The Beautyrest Gel Memory Foam contours under your curves, but the Triple-Stranded Pocketed Coil core pushes back, so it never turns into the slow, enveloping sink of an all-foam bed. Slide to the edge and the Apex Top earns its name: sit on the side and the perimeter holds instead of caving, and lie all the way out and you are still on a supportive surface, not perched on a slope. That is why a 15.25-inch medium sleeps bigger than its footprint. Coming off an older bed that slept hot and went soft at the sides, that contrast is what you feel first: the Micro Diamond layer keeps the surface cooler, and the reinforced edge gives back the width you lost. It also pairs with an adjustable base.
Who it's not for, said straight
- If you want the most accessible Black medium, the Series One Medium gives the same true-medium feel without the Series Two cooling and edge upgrades.
- If you want plush or firm specifically, this is a true medium; the plush and firm models bracket it in the Black lineup.
- If you want the memory-foam hug, this is a responsive coil hybrid, not an enveloping foam bed.

A medium that fixed the edges and deepened the comfort
The Apex Top Medium takes the Series One medium recipe (Beautyrest® Gel Memory Foam over a Triple-Stranded Pocketed Coil® core) and applies the Series Two upgrades, layer by layer.
At the surface: Sleep Climate™ quilting works with Micro Diamond™ Memory Foam, which is infused with heat-conductive particles to draw warmth away from your body, so the bed runs cooler than Series One.
Comfort layer: a deeper, more contouring layer of Beautyrest® Gel Memory Foam than Series One carries, cradling more of your curves for pressure relief on your hips and shoulders.
Support core: the Triple-Stranded Pocketed Coil® core uses three braided steel strands per coil, each individually wrapped, so coils move independently. That holds a true-medium feel and keeps motion separation strong.
Perimeter: the Apex Top adds BeautyEdge® encasement, a reinforced border that keeps the edges from collapsing. That is what makes a 15.25-inch medium feel bigger than its footprint: the full width sleeps usable and the side holds when you sit.
For the same true-medium feel without the Series Two upgrades, the Series One Medium is the value pick. Feel both 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 people who use the whole bed
Couples: the BeautyEdge® perimeter means both of you can sleep closer to the sides without rolling toward the middle, and the pocketed coils keep one partner's movement off the other.
Back and combination sleepers: a true medium with deeper contouring suits the widest range of positions, supporting the spine while relieving pressure as you switch.
Side sleepers: the deeper Beautyrest® Gel Memory Foam gives enough give at the shoulders and hips without letting you sink past support.
Hot sleepers: the Micro Diamond™ and Sleep Climate™ cooling step-up makes this the medium to feel if Series One ran a touch warm for you.
Anyone who sits on the edge to put on shoes, read, or get up: the Apex Top keeps the perimeter from sagging year after year.
Probably not for you if you want the cheapest Black medium (the Series One Medium), a specifically plush or firm feel, or the enveloping hug of an all-foam bed (this is a responsive coil hybrid).

Frequently asked questions
What does the Apex Top add?
Upgraded edge support through BeautyEdge® encasement: a reinforced perimeter so the edges of the mattress stay firm. In practice that means more usable sleeping surface, a solid seat on the side of the bed, and a steadier feel getting in and out. It is the signature of this Series Two model.
How is Series Two different from Series One?
Series Two keeps everything Series One does and adds upgrades: enhanced cooling through Sleep Climate™ Technology and Micro Diamond™ Memory Foam, a deeper and more contouring comfort layer, and, on this model, the Apex Top edge support. The Series One Medium is the same true-medium feel at the more accessible tier.
How firm is it?
A true medium, about 5 out of 10. Enough contour to relieve pressure, enough support to keep your back honest, suitable for back, side, and combination sleepers.
Does it sleep cool?
It is built to. Sleep Climate™ quilting works with Micro Diamond™ Memory Foam, which is infused with heat-conductive particles that pull warmth away from your body, and the pocketed-coil core breathes more than an all-foam bed. If Series One ran a touch warm for you, this is the cooler step-up.
Is it good for couples?
Especially. The BeautyEdge® perimeter lets both sleepers use the full width without rolling to the center, and the Triple-Stranded Pocketed Coils keep movement from crossing the bed.
What is a Triple-Stranded Pocketed Coil?
It is Beautyrest's support coil: each coil is built from three braided steel strands and individually wrapped in fabric, so it flexes on its own rather than as a connected unit. That gives you point-by-point support that holds a true-medium feel and keeps a partner's motion from traveling across the bed.
Can I use it with an adjustable base?
Yes. This mattress is compatible with an adjustable base if you like to sleep with your head or feet raised.
How tall is it, and what sheets do I need?
It is a substantial 15.25 inches tall, taller than the Series One mediums to make room for the deeper comfort layer and the Apex Top. Plan on deep-pocket sheets and measure against your frame and headboard before delivery.
How do delivery and the comfort guarantee work?
The team delivers across Kentucky, usually next business day when your size is in stock, and hauls your old mattress away. 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 (no cash refund).
