Beautyrest Black Hybrid FAQs

Our introduction to the Beautyrest Black® Hybrid line is the BX-Class, which features the highly supportive zoned T3 Pocketed Coil technology, plant-based cooling, and the luxurious aesthetics that come with the Beautyrest Black brand.

The Beautyrest Black® LX-Class features our premier support system: zoned T3 Pocketed Coil® Technology. Our new plant-based cooling technology, moreover, helps provide additional cooling power. And for even more support, AirCool® Memory Foam provides pressure point relief.

In addition to support -- T3 Pocketed Coil® Technology -- and cooling features found in our LX-Class, Beautyrest Black® CX-Class models include comfort and pressure-relieving upgrades. A rich layer that includes silk, alpaca, and cashmere, for instance, provides unmatched comfort and breathability. Meanwhile, Self-Response™ Latex provides unique support for your body.

Beautyrest Black® KX-Class, the premier offering in our most advanced collection yet, includes everything you’ll find in the CX-Class and LX-Class -- zoned T3 Pocketed Coil® Technology and a new plant-based cooling technology -- plus an extra layer of 2K Nano Coils for our most substantive support system. Additionally, KX-Class models feature up to 2x more memory foam for even more pressure relief.

The Hybrid products are a cross between an all-memory foam mattress and innerspring mattresses. As far as the Hybrid goes, the top layer on which you lay is memory foam, all the way down to the layer of foam above the springs (the layer above the springs is usually the only non-memory foam layer and will be ½” polyurethane). When you lay on a Hybrid mattress, it usually feels more comparable to a traditional foam mattress, with a sinking-in feeling, but combines the bounciness of an innerspring mattress.

In the traditional lines, the foam layers are a combination of polyurethane foam and memory foam layers. The top layers will be polyurethane foam followed by memory foam layers deeper down in the mattress. Memory foam is a slow-recovery material, whereas, polyurethane foam is a quick-response foam. This will provide a very different feel than a Hybrid product.

Additionally, Hybrid mattresses tend to have a flatter top, while traditional mattresses will have the more common tufted top.

Depending on which mattress option you choose, the height of the Beautyrest Black Hybrid Mattress will range between 12.5" and 15".

When selecting the BX-Class you will have the option to choose between Firm or Plush.

When selecting the LX-Class you will have the option to choose between Firm, Medium, or Plus.

When selecting the CX-Class option you can choose between Medium or Plush.

When selecting the KX-Class option you can choose either a Firm or a Plush option.
