Beautyrest Black FAQs

The Beautyrest Black mattresses come in a variety of firmnesses and styles, from traditional tight-top mattresses to pillow tops. They also all feature our T3 Pocketed Coil support system for the most consistent support and durability, our all-night cooling technology, BlackICE with plant-based cooling, to provide more cooling power to keep you comfortable as you fall asleep and all night long, and our Technoluxe Memory Foams for the best pressure relief out there, the differences between the 4 classes are as follows.

Our introduction to the Beautyrest Black line is the B-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 L Class is the perfect step up if you are looking for an even higher level of comfort. Not only does it offer everything the B-Class has, but it also includes additional cooling features and added support.

The C-Class models were designed to implement even more comfort and immediate pressure relief, on top of what is offered in the L-Class line. The C-Class models will include comfort layers made with Alpaca, Cashmere, and Silk Fibers to incorporate more comfort in your mattress while continuing to ensure airflow and breathability. The C-Class line will also add a layer of Self-Response Latex to incorporate a unique support and pressure relief specific for your hips and shoulders.

The K-Class models feature all the benefits of the C-Class, but the K-Class will provide up to 30% more pressure point relief than the C-Class because of the utilization of our 2K Nano-Coils. These unique coils were designed to provide enhanced conformability and pressure relief, with individualized back support for each individual shape. The K-Class line has the most upgrades and sleep benefits of all 3 lines and will provide the most luxurious sleep experience by incorporating our Dynamic Response Memory Foam for more conforming support and maximized airflow.

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.

When selecting the B-Class you will have the option to choose between Extra Firm, Medium, Plush.

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

When selecting the C-Class option you can choose between Extra Firm, Firm, Medium, or Plush.

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

Depending on which mattress option you choose, the height of the Beautyrest Black Mattress will range between 13.5" and 16.5".
