Beautyrest Black® Series Two 15.25" Medium Apex Top Hybrid Mattress

The honest verdict: the Series Two Apex Top Medium is the standout of the Series Two line, and the reason is the edges. Its Apex Top is engineered for upgraded edge support, so the whole surface stays usable. You can sleep, sit, and roll near the perimeter without the rolling-off-a-hill feeling cheaper beds have. Add the Series Two step-up over Series One (enhanced cooling and deeper, more contouring pressure relief) on a true-medium feel, and you get the most well-rounded medium in the Black core line. If you use the full width of your bed or share it, this is the one to feel.

What it's made of, and what that does for you

• Apex Top edge support. A reinforced perimeter so the edges hold firm: more usable sleeping surface, an easier seat on the side, and a steadier feel getting in and out.
• The Series Two cooling and comfort step-up. Sleep Climate quilting and a deeper Beautyrest Gel Memory Foam comfort layer than Series One. It cradles more of your curves while running cooler.
• Triple-Stranded Pocketed Coil core. Individually-wrapped coils carry a true-medium support and deliver Black's signature motion separation under the upgraded comfort layers.
• 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 deep-pocket sheets.
• Premium Black build, 10-year warranty. CertiPUR-US certified foams, 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 the 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 to put on your shoes 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 all-foam bed that slept hot and went soft at the sides, that is the contrast you feel first, and the reinforced edge gives back the width you lost. It is also compatible with an adjustable base if you like to sleep with your head or feet raised.

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 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.
