Beautyrest Black Hybrid Mattresses: Shared Features

There are seven models in the Beautyrest Black Hybrid collection of mattresses, which was redesigned for the 2023 model year, with the BX-Class versions most recently added for 2024. With cooling and zoned support features, the Black Hybrid line is distinguished by including more memory foam in the comfort layers than other Beautyrest mattresses.

These are luxury mattresses, with a traditional look, and mattress heights ranging up to 15 inches.

It's also worth noting how Beautyrest defines "hybrid." GoodBed uses the term "Hybrid Mattress" to indicate any bed that has springs for support along with foam comfort materials on top. Those comfort materials could be regular polyurethane foam, or latex, or memory foam, or any combination, in any quantity.

Beautyrest, however, uses the term 'hybrid' more narrowly. While almost all of Beautyrest's mattresses, use fabric-encased coils along with some degree of comfort foams, the mattresses in the Black Hybrid series use the most memory foams, and have a high degree of that slow, melting-into-the-bed sensation we associate with memory foam. All of the Black Hybrid collection mattresses are traditional tight-cover style beds (as opposed to pillow-top or quilt-top models). with stretchy covers that can mold around the memory foam when it's compressed.

Beautyrest uses an "X" in the model numbers to denote 'hybrid' so you'll see these models sold as the "Beautyrest Black Hybrid LX-Class Medium" and so on.

There are four levels in the Black Hybrid collection. The BX-Class is the base model. the LX, CX and KX mattresses add additional features and height. The BX-Class models are a more recent addition to the collection, and we have a separate video on them.

T3 Pocket Coils

Beautyrest is using their signature triple-wire coils in the Black Hybrid collection. Three wires are twisted into a cable, which is then twisted into the coil. In the mattresses, Beautyrest alternates rows of the T3 coils with regular pocketed coils. The regular coils vary in gauge to help give a bed its firmness or softness. But all of the mattresses in the Black Hybrid series employ the alternating coil system.

New for these models in the Beautyrest Black Hybrid collection is a zoning system; the coils in the central third of the bed are firmer, meant to better support your hips, the heaviest part of the body.

BlackIce Hybrid Cooling Features

The Beautyrest Black Hybrid mattresses feature cooling technology called BlackIce, comprised of phase-change material on the top of the cover. Simply put, phase change material is similar to wax beads; the beads feel cool to the touch, and as your body warms them, they melt and lose their benefit. These materials are meant to keep you cooler while you fall asleep.

Notably the phase-change beads are made of plant-based canola oil rather than petroleum.

AirCool Memory Foam

All models have at least an inch of Beautyrest's AirCool memory foam under the cover. This is a very slow responding foam, meaning it takes a long time to come back to shape after being depressed. This foam has lots of that ooey-gooey feeling you associate with memory foam.

The AirCool foam is used in different amounts depending on the model, and in conjunction with other types of memory foams and standard foams.

Beautyrest Black Hybrid BX-Class

There are two BX-Class mattresses in the Beautyrest Black Hybrid collection, a Firm and a Plush. Those are the distinctions given by Beautyrest to indicate relative softness, cushioning, and general plushness. At GoodBed, we separate softness/feel from cushioning/conformance. So our GoodBed ratings can often differ from manufacturer ratings.

BX-Class Firm: In our system, we rate overall softness also as a Firm, with cushioning depth being about average, and a blend of feeling like you are sinking into your mattress versus floating on top. Memory feel is about average, with a little of that melting feeling we associate with memory foam. 

BX-Class Plush: Softness on our scale is a Medium Soft, with deeper than average cushioning depth and more memory feel than the Firm version. 

Both models are 12.5" tall.

Both BX-Class mattresses have a good bit of bounce, and excellent edge support.

Beautyrest Black Hybrid LX-Class

There are three LX-Class mattresses in the Beautyrest Black Hybrid collection, a Firm, a Medium and a Plush. All of these have more of that melty memory feel than the BX-Class versions.

LX-Class Firm: In our system, we rate overall softness also as a Firm, with cushioning depth being about average, and a blend of feeling like you are sinking into your mattress versus floating on top.

LX-Class Medium: We rate softness still as a Firm on our scale, but the LX-Class Medium has slightly deeper cushioning than average, so you get more of a sinking-into-the-mattress feeling.

LX-Class Plush: Softness on our scale is a Medium, but this model does have the most cushioning depth and the most memory feel of the three, so more of that sinking in feeling, along with the slow melting sensation of memory foam.

All three models are 13.5" tall.

The three LX-Class mattresses all have more than average memory feel, so plenty of that melting sensation we associate with memory foam. They also all have a good bit of bounce, some of which is absorbed by the comfort foams on top.

Beautyrest Black Hybrid CX-Class

The mattresses in the CX-Class are the middle models in the Beautyrest Black Hybrid collection, with they have additional pressure-relief and cooling features beyond the LX-Class mattresses.

These two mattresses both include a 1/2" sheet of latex, pierced with pin-core holes. Latex is a quick-responding, springy material that adds some pressure relief as well as air flow.

A second cooling/comfort feature is a 1" layer of a spongy material made from natural alpaca wool, cashmere and sink blended with some synthetic fibers. This is a springy, airy layer that adds airflow and moisture-wicking properties.

CX-Class Medium: The medium version, which we found to be a Medium Firm on our GoodBed scale, is a 13.5" tall mattress that includes a total of 2.5" of memory foam, the latex layer and the cashmere/wool comfort material in addition to the same pocket coil unit employed in all of the Black Hybrid mattresses. Although the overall feel is on the firmer side, cushioning and conformance are both deeper than average, so you get that sinking-into-the-mattress feeling.

CX-Class Plush: With a 15" total height, the Plush version has a total of 4" of memory foam, latex and cashmere/wool comfort material on top of the coil unit. This mattress is one of the softest in the collection, and we call it is Medium Soft on our scale. It also has deeper cushioning than the Medium version.

Both of the CX-Class models have some bounce, but a lot of that bounce is absorbed by the layers of comfort materials on tops of the springs.

Beautyrest Black Hybrid KX-Class

At the top of the range is the KX-Class mattress, which comes in a Firm and a Plush, and at 15" tall, is the tallest, thickest mattress in the collection. In addition to the features of the LX-Class and CX-Class mattresses, the KX-Class adds a 1" tall layer of quarter-sized nano-coils. These add additional support and especially conformance as your body depresses the mattress.

KX-Class Firm: With 3.5" of memory foam, we judged this model a Medium Firm on our scale, with slightly deeper than average cushioning, so you get a blend of floaty support versus sinking into the bed.

KX-Class Plush: This is the softest mattress in the collection, and we judged it a Soft on our scale. It also has the most ooey-gooey memory feel and very deep cushioning/sinking into the bed feeling.

Both mattress have a medium level of bounce, with the comfort foams absorbing motion.
